Precision Quad Comparators

The HA-4900 series are monolithic, quad, precision comparators offering fast response time, low offset voltage, low offset current and virtually no channel-to-channel crosstalk for applications requiring accurate, high speed, signal leveldetection.Thesecomparatorscansensesignals at groundlevel while beingoperatedfrom either a single +5V supply (digital systems) or from dual supplies (analog networks) up to ±15V.The HA-4900 series contains a unique current driven output stage which can be connected to logic system supplies (V

LOGIC

levels directly compatible (no external components needed) with any standard logic or special system logic levels. In combination analog/digital systems, the design employed in the HA-4900 series input and output stages prevents troublesome ground coupling of signals between analog and digital portions of the system.

These comparators’ combination of features make them ideal components for signal detection and processing in data acquisition systems, test equipment and microprocessor/analog signal interface networks.

CAUTION: Stresses above those listed in “Absolute Maximum Ratings” may cause permanent damage to the device. This is a stress only rating and operation of the device at these or any other conditions above those indicated in the operational sections of this speciﬁcation is not implied.

NOTES:

1. Maximum power dissipation, including output load, must be designed to maintain the junction temperature below 175oC for ceramic packages, and below 150oC for plastic packages.

2. Total Power Dissipation (T.P.D.) is the sum of individual dissipation contributions of V+, V- and V vs Supply Voltages (see Performance Curves). The calculated T.P.D. is then located on the graph of Maximum Allowable Package Dissipation vs Ambient Temperature to determine ambient temperature operating limits imposed by the calculated T.P.D. (See Performance Curves). For instance, the combination of +15V, -15V, +5V, 0V (V+, V-, V 0V gives a T.P.D. of 450mW.

3. θJA is measured with the component mounted on an evaluation PC board in free air.

NOTES:

4. Minimum differential input voltage required to ensure a defined output state.

5. Input bias currents are essentially constant with differential input voltages up to ±9V. With differential input voltages from ±9V to ±15V, bias current on the more negative input can rise to approximately 500µA. This will also cause higher supply currents.

6. VCM= 0V. Input sensitivity is the worst case minimum differential input voltage required to guarantee a given output logic state. This parameter includes the effects of offset voltage and voltage gain.

7. For tPD(1); 100mV input step, -10mV overdrive. For tPD(0); -100mV input step, 10mV overdrive. Frequency ≈100Hz; Duty Cycle ≈50%; Inverting input driven. See Figure 1 for Test Circuit. All unused inverting inputs tied to +5V.
