MAX11154

18-Bit, 500ksps, 0 to 5V SAR ADC with Internal Reference in TDFN

Industry's Smallest, 18-Bit SAR ADC with Internal Reference


Please check latest availability status for a specific part variant.

Description

The MAX11154 18-bit, 500ksps, SAR ADC offers excellent AC and DC performance with unipolar input range, small size, and internal reference. The MAX11154 integrates an optional internal reference and buffer, saving additional cost and space.

This ADC typically achieves 93.8dB SNR and -105.8dB THD. The device guarantees 18-bit no-missing codes and ±2 LSB INL (typ).

The MAX11154 communicates using an 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 MAX11154 is offered in a 12-pin, 3mm x 3mm, TDFN package and is specified over the -40°C to +85°C temperature range.
