Description

The MAX11165 16-bit, 250ksps, SAR ADC offers excellent AC and DC performance with unipolar input range, small size, and internal reference. The MAX11165 integrates an optional internal reference and buffer, saving additional cost and space.

This ADC achieves 92.2dB SNR and -105dB THD. The MAX11165 guarantees 16-bit no-missing codes.

The MAX11165 communicates using an SPI-compatible serial interface at 2.5V, 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 MAX11165 is offered in a 12-pin, 3mm x 3mm, TDFN package and is specified over the -40°C to +85°C temperature range.
