LTC2381-16 - Low Power SAR ADC

General Description

The LTC®2381-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC.

Operating from a 2.5V supply, the LTC2381-16 has a ±2.5V fully differential input range.

The LTC2381-16 consumes only 3.25mW and achieves ±2LSB INL max, no missing codes at 16-bits and 92dB SNR.
