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 6ppm/°C reference with internal buffer, saving the cost and space of an external reference. 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.
