By Maxim Integrated 112
Maxim Integrated's MAX11168 is a 16-bit, 500 ksps, SAR ADC offering excellent AC and DC performance with true bipolar input range, internal reference, and small size. The MAX11168 measures a ±5 V (10 VP-P) input range while operating from a single 5 V supply. Patented charge-pump architecture allows direct sampling of high-impedance sources. The MAX11168 integrates a low drift reference with internal buffer, saving the cost and space of an external reference.
This ADC achieves 92.3 dB SNR and -101 dB THD. The MAX11168 guarantees 16-bit no-missing codes and ±0.75 LSB INL (typ).
The MAX11168 communicates using an SPI-compatible serial interface at 2.5 V, 3 V, 3.3 V, or 5 V 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 MAX11168 is offered in a 10-pin, 3 mm x 5 mm, µMAX® package and is specified over the -40°C to +85°C.
