MAX11152
18-Bit, 500ksps, +5V Unipolar Input, SAR ADC,
in Tiny 10-Pin µMAX
General Description
The MAX11152 is an 18-bit, 500ksps, +5V unipolar pseudo-
differential input SAR ADC that offers excellent AC and DC
performance in a small standard package.
This ADC typically achieves 95dB SNR, -106dB THD, and
±2 LSB INL, ±0.5 LSB DNL. The MAX11152 guarantees
18-bit no-missing codes.
The MAX11152 communicates using a SPI-compatible
serial interface at 2.5V, 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 MAX11152 is offered in a 10-pin, 3mm x 5mm,
µMAXM package and is specified over the -40NC to +85NC
temperature range.
