MAX11167：16-Bit, 250ksps, ±5V SAR ADC with Internal Reference in TDFN

Industry's Smallest, True Bipolar ±5V, 16-Bit ADCs

The MAX11167 16-bit, 250ksps, SAR ADC 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. A patented charge-pump architecture allows direct sampling of high-impedance sources. The MAX11167 integrates an optional 6.7ppm/°C reference with internal buffer, saving the cost and space of an external reference. This ADC achieves 93.2dB SNR and -102.5dB 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. The MAX11167 is offered in a 12-pin, 3mm x 3mm, TDFN package and is specified over the -40°C to +85°C temperature range.
