EVALUATION KIT AVAILABLE 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 pseudodifferential 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.
