SAR 18-bit ADC with ref comes in 12-pin package
The MAX11156 produces 94.6dB SNR and -105dB THD (typ). The MAX11156 guarantees 18-bit no-missing codes.
The MAX11156 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 in parallel for multichannel applications and provides a busy indicator option for simplified system synchronization and timing.
The MAX11156 is offered in a 12-pin, 3mm x 3mm, TDFN package and is specified over the -40°C to +85°C temperature range.

Maxim Integrated Products has introduced its smallest 12-pin, 18-bit successive approximation register (SAR) analogue-to-digital converter (ADC).
Available in a 3x3mm TDFN package, the MAX11156 has an internal reference and reference buffer.
It supports a ±5V input from a single positive 5V input rail, which can eliminate the need for negative power supplies and simplifies designs.
The device has an 18-bit resolution and a 500ksample/s sampling rate.
DC accuracy is 0.5 LSB DNL and 2.5 LSB INL (typ)). AC performance is 94.6dB SNR and -105dB THD (typ)). The device has an SPI-compatible serial interface, which can be used to daisy-chain multiple ADCs in parallel for multichannel applications.
