MAX11162
16-Bit, 500ksps, +5V Unipolar Input,
SAR ADC, in Tiny 10-Pin µMAX
General Description
The MAX11162 is a 16-bit, 500ksps, +5V unipolar
pseudo-differential input SAR ADC offering excellent AC
and DC performance in a small standard package.
This ADC typically achieves 93dB SNR, -105dB THD, and
±0.6 LSB INL, ±0.2 LSB DNL. The MAX11162 guarantees
16-bit no-missing codes.
The MAX11162 communicates using an SPI-compatible
serial interface at 2.3V, 3V, 3.3V, or 5V logic.
The serial interface can be used to daisy-chain multiple
ADCs for multichannel applications and provides a busy
indicator option for simplified system synchronization
and timing.
The MAX11162 is offered in a 10-pin, 3mm x 5mm,
µMAX® package and is specified over the -40°C to +85°C
temperature range.

Stresses beyond those listed under “Absolute Maximum Ratings” may cause permanent damage to the device. These are stress ratings only, and functional operation
of the device at these or any other conditions beyond those indicated in the operational sections of the specifications is not implied. Exposure to absolute maximum
rating conditions for extended periods may affect device reliability.
