MAXIM MAX11150EUB+

The MAX11150 is an 18-bit, 500ksps, SAR ADC offering excellent AC and DC performance with unipolar input range, internal reference, and small size. The MAX11150 measures a +5V (0 to 5V) input range and can operate with single 5V supply. The MAX11150 integrates a low drift reference with internal buffer, saving the cost and space of an external reference. This ADC achieves 93.0dB SNR and -101.2dB THD. The MAX11150 guarantees 18-bit no-missing codes and ±3.7 LSB INL (typ). The MAX11150 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 MAX11150 is offered in a 10-pin, 3mm x 5mm, µMAX package and is specified over the -40℃ to +85℃ temperature range.
