16-bit, 250ksps SAR ADCs offer excellent AC and DC performance

The MAX11167 16-bit, 500ksps/250ksps, SAR ADCs offers excellent AC and DC performance with true bipolar input range, small size, and internal reference. The MAX11167 measures a ±5V (10VP-P) input range while operating from a single 5V supply. Patented charge-pump architecture allows direct sampling of high-impedance sources. The MAX11167 integrates an optional 6ppm/°C reference with internal buffer, saving the cost and space of an external reference.

These ADCs achieve 92.6dB SNR and -105dB THD. The MAX11167 guarantees 16-bit no-missing codes and ±0.5 LSB INL (typ).

The MAX11167 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 in parallel for multichannel applications and provides a busy indicator option for simplified system synchronization and timing.

It is offered in 12-pin, 3mm x 3mm, TDFN packages and are specified over the -40°C to +85°C temperature range.
