The MAX11161 is a 16-bit, 250ksps, SAR ADC offering excellent AC and DC performance with true unipolar input range, internal reference, and small size. The MAX11161 measures a +5V (0 to 5V) input range and can operate with a single 5V supply. The MAX11161 integrates a low drift reference with internal buffer, saving the cost and space of an external reference.

This ADC achieves 92.2dB SNR at 10kHz and -106.5dB THD. The MAX11161 guarantees 16-bit no-missing codes and ±0.8 LSB INL (typ).

The MAX11161 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 MAX11161 is offered in a 10-pin, 3mm x 5mm, µMAX® package and is specified over the -40°C to +85°C temperature range.
