General Description
The MAX9039–MAX9043 and MAX9050–MAX9053 fea­ture combinations of low-power comparators and preci­sion voltage references. Their operating voltage range makes them ideal for both 3V and 5V systems. The MAX9039/MAX9040/MAX9041/MAX9050/MAX9051 have a single comparator and reference consuming only 40µA of supply current. The MAX9042/MAX9043/ MAX9052/MAX9053 have dual comparators and one reference, and consume only 55µA of supply current. Low-voltage operation and low supply current make these devices ideal for battery-operated systems.
The comparators feature rail-to-rail inputs and outputs, with a common-mode input voltage range that extends 250mV beyond the supply rails. Input bias current is typically 1.0pA, and input offset voltage is typically
0.5mV. Internal hysteresis ensures clean output switch­ing, even with slow-moving input signals. The output stage features a unique design that limits supply cur­rent surges while switching, virtually eliminating supply glitches typical of many other comparators. This design also minimizes overall power consumption under dynamic conditions. The comparator outputs have rail­to-rail, push-pull output stages that sink and source up to 8mA. The propagation delay is 400ns, even with the low-operating supply current.
The reference output voltage is set to 1.23V in the MAX9039, to 2.048V in the MAX9040–MAX9043, and to
2.500V in the MAX9050–MAX9053. The MAX9040– MAX9043 and the MAX9050–MAX9053 are offered in two grades: an A grade with 0.4% initial accuracy and 6ppm/°C tempco, and a B grade with 1% initial accura­cy and 100ppm/°C tempco. The voltage references feature a proprietary curvature-correction circuit and laser-trimmed thin-film resistors. These series-mode ref­erences can sink or source up to 500µA of load current.

Note 1: This device is constructed using a unique set of packaging techniques that impose a limit on the thermal profile the device
can be exposed to during board-level solder attach and rework. This limit permits only the use of the solder profiles recom­mended in the industry-standard specification, JEDEC 020A, paragraph 7.6, Table 3 for IR/VPR and Convection Packaging Reflow. Preheating is required. Hand or wave soldering is not allowed.

Detailed Description
The MAX9039–MAX9043 and MAX9050–MAX9053 fea­ture single/dual, low-power, low-voltage comparators and a precision voltage reference. They operate from a single 2.5V to 5.5V (MAX9039/MAX904_) or 2.7V to
5.5V (MAX905_) supply. The single comparators with reference, (MAX9039/MAX9040/MAX9041/MAX9050/ MAX9051 consume only 40µA of supply current, while the dual comparators with reference (MAX9042/ MAX9043/MAX9052/MAX9053) consume only 55µA of supply current. Their common-mode input range extends 0.25V beyond each rail. Internal hysteresis ensures clean output switching, even with slow-moving input signals.
The output stage employs a unique design that mini­mizes supply current surges while switching, virtually eliminating the supply glitches typical of many other comparators. Large internal output drivers allow rail-to­rail output swing that can sink and source up to 8mA of current.
The precision reference uses a proprietary curvature­correction circuit and laser-trimmed thin-film resistors, resulting in a temperature coefficient of less than 30ppm/°C over the extended temperature range and initial accuracy of 0.4% (A grade). The reference output voltage is set to
1.23V in the MAX9039, 2.048V in the MAX9040–MAX9043, and to 2.500V in the MAX9050–MAX9053.
Comparator Input Stage Circuitry
The devices’ input common-mode range extends from (VEE- 0.25V) to (VCC+ 0.25V). These comparators may operate at any differential input voltage within these lim­its. Input bias current is typically 1.0pA if the input volt-
age is between the supply rails. Comparator inputs are protected from overvoltage by internal body diodes connected to the supply rails. As the input voltage exceeds the supply rails, these body diodes become forward biased and begin to conduct. Consequently, bias currents increase exponentially as the input volt­age exceeds the supply rails.
Comparator Output Stage Circuitry
The comparators in these devices contain a unique output stage capable of rail-to-rail operation with loads up to 8mA. Many comparators consume orders-of-mag­nitude more current during switching than during steady-state operation. However, with this family of com­parators, the supply current change during an output transition is extremely small. The Typical Operating Characteristics graph Supply Current vs. Switching Frequency shows the minimal supply current increase as the output switching frequency approaches 1MHz. This characteristic reduces the need for power-supply filter capacitors to reduce glitches created by compara­tor switching currents. Another advantage realized in high-speed, battery-powered applications is a substan­tial increase in battery life.
Applications Information
Additional Hysteresis
These comparators have ±3mV internal hysteresis. Additional hysteresis can be generated with two resis­tors using positive feedback (Figure 1). Use the follow­ing procedure to calculate resistor values:
1) Calculate the trip points of the comparator using these formulas:
and
VTHis the threshold voltage at which the comparator switches its output from high to low as VINrises above the trip point. VTLis the threshold voltage at which the comparator switches its output from low to high as VINdrops below the trip point.
2) The hysteresis band will be:

where R1 ≈ 100kΩ, VTH= 2.525V, and VTL= 2.475V.
Board Layout and Bypassing
Power-supply bypass capacitors are not typically need­ed, but would be called for in cases where supply impedance is high, supply leads are long, or excessive noise is expected on the supply lines. Use 100nF bypass capacitors under these conditions. Minimize signal trace lengths to reduce stray capacitance.
Reference Output/Load Capacitance
The MAX9039/MAX904_/MAX905_ do not require an output capacitor on REF for frequency stability. They are stable for capacitive loads up to 4.7nF. However, in applications where the load or the supply can experi­ence step changes, an output capacitor will reduce the
amount of overshoot (or undershoot) and assist the cir­cuit’s transient response. When an application is not subject to transient conditions, the REF capacitor can be omitted.
Biasing for Data Recovery
Digital data is often embedded into a bandwidth- and amplitude-limited analog path. Recovering the data can be difficult. Figure 2 compares the input signal to a time-averaged version of itself. This self-biases the threshold to the average input voltage for optimal noise margin.
Even severe phase distortion is eliminated from the dig­ital output signal. Be sure to choose R1 and C1 so that:
where f
CAR
is the fundamental carrier frequency of the
digital data stream.
UCSP Package Consideration
For general UCSP package information and PC layout considerations, please refer to Maxim Application Note,"Wafer-Level Chip-Scale Package."
UCSP Reliability
The chip-scale package (UCSP) represents a unique packaging form factor that may not perform equally to a packaged product through traditional mechanical relia­bility tests. UCSP reliability is integrally linked to the user’s assembly methods, circuit board material, and usage environment. The user should closely review these areas when considering use of a UCSP. Performance through Operating Life Test and Moisture Resistance remains uncompromised as it is primarily determined by the wafer-fabrication process.
Mechanical stress performance is a greater considera­tion for a UCSP. UCSPs are attached through direct solder contact to the user’s PC board, foregoing the inherent stress relief of a packaged product lead frame. Solder joint contact integrity must be considered. Information on Maxim’s qualification plan, test data, and recommendations are detailed in the UCSP appli­cation note, which can be found on Maxim’s website at www.maxim-ic.com.
