Description

The MAX11262 is a 14-bit, 500ksps, +5V unipolar pseudo-differential input SAR ADC offering excellent AC and DC performance in a small standard package.

This ADC typically achieves 85.4dB SNR, -102dB THD, and ±0.2 LSB INL (typ), ±0.12 LSB DNL (typ). The MAX11262 guarantees 14-bit no-missing codes.

The MAX11262 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 MAX11262 is offered in a 10-pin, 3mm x 5mm, µMAX® package and is specified over the -40°C to +85°C temperature range.
