MAX11163EUB+

The MAX11163EUB+ is a 16bit, 250Ksps, +5V unipolar input, SAR ADC in 10 pin µMAX package. The Single-channel, pseudo-differential SAR ADC with maximum throughput rates of 250Ksps. This ADC measures a unipolar input voltage interval from 0V to VREF. The external reference interval ranges from 2.5V to VDD. Both inputs, AIN+ and AIN- are sampled with an integrated pseudo-differential track and hold (T/H) exhibiting no pipeline delay or latency making this ADC ideal for multiplexed channel applications. This ADC typically achieves 93.8dB SNR, -106dB THD, ±0.5LSB INL and ±0.2LSB DNL. IC communicates using an SPI-compatible serial interface at 2.5V, 3V, 3.3V or 5V logic. 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. It requires 1µs to acquire input sample on an internal (T/H) & converts sampled signal to 16bits of resolution using an internally clocked converter.

• Analogue supply voltage range from 4.75V to 5.25V & digital supply of 2.3V to 5.25V
