MAXIM MAX1043, MAX1046, MAX1049 Technical data

General Description

The MAX1040–MAX1043/MAX1046–MAX1049 integrate a
multichannel, 10-bit, analog-to-digital converter (ADC)
and a quad, 10-bit, digital-to-analog converter (DAC) in a
single IC. The devices also include a temperature sensor
and configurable general-purpose I/O ports (GPIOs) with
a 25MHz SPI™-/QSPI™-/MICROWIRE™-compatible seri­al interface. The ADC is available in a 4 or an 8 input­channel version. The four DAC outputs settle within 2.0µs,
and the ADC has a 300ksps conversion rate.

All devices include an internal reference (2.5V or 4.096V)
providing a well-regulated, low-noise reference for both
the ADC and DAC. Programmable reference modes for
the ADC and DAC allow the use of an internal reference,
an external reference, or a combination of both. Features
such as an internal ±1°C accurate temperature sensor,
FIFO, scan modes, programmable internal or external
clock modes, data averaging, and AutoShutdown™ allow
users to minimize both power consumption and proces­sor requirements. The low glitch energy (4nV•s) and low
digital feedthrough (0.5nV•s) of the integrated quad
DACs make these devices ideal for digital control of fast­response closed-loop systems.

The devices are guaranteed to operate with a supply volt­age from +2.7V to +3.6V (MAX1041/MAX1043/MAX1047/
MAX1049) and from +4.75V to +5.25V (MAX1040/
MAX1042/MAX1046/MAX1048). These devices consume

2.5mA at 300ksps throughput, only 22µA at 1ksps
throughput, and under 0.2µA in the shutdown mode. The
MAX1042/MAX1043/MAX1048/MAX1049 offer four GPIOs
that can be configured as inputs or outputs.

The MAX1040–MAX1043/MAX1046–MAX1049 are avail­able in 36-pin thin QFN packages. All devices are speci­fied over the -40°C to +85°C temperature range.

Note 1: Tested at DVDD= AVDD= 3.6V (MAX1041/MAX1043/MAX1047/MAX1049), DVDD= AVDD= 5.25V (MAX1040/MAX1042/

MAX1046/MAX1048).

Note 2: Offset nulled.
Note 3: No bus activity during conversion. Conversion time is defined as the number of conversion clock cycles multiplied by the

clock period.

Note 4: See Table 5 for reference-mode details.
Note 5: Not production tested. Guaranteed by design.
Note 6: See the ADC/DAC References section.
Note 7: Fast automated test, excludes self-heating effects.
Note 8: Specified over the -40°C to +85°C temperature range.
Note 9: REFSEL[1:0] = 00 or when DACs are not powered up.
Note 10: DAC linearity, gain, and offset measurements are made between codes 115 and 3981.
Note 11: The DAC buffers are guaranteed by design to be stable with a 1nF load.
Note 12: Time required by the DAC output to power up and settle within 1 LSB in the external reference mode.
Note 13: All DAC dynamic specifications are valid for a load of 100pF and 10kΩ.
Note 14: Only one digital output (either DOUT,

EOC, or the GPIOs) can be indefinitely shorted to either supply at one time.

Note 15: All digital inputs at either DV

DD

or DGND. DVDDshould not exceed AVDD.

Note 16: See the Reset Register section and Table 9 for details on programming the SLOW bit.
Note 17: Clock mode 11 only.
