Typical Application

Description

The LTC®2370-16 is a low noise, low power, high speed 16-bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2370-16 has a 0V to V_REF pseudo-differential unipolar input range with V_REF ranging from 2.5V to 5.1V. The LTC2370-16 consumes only 19mW and achieves ±0.85LSB INL maximum, no missing codes at 16 bits with 94dB SNR.

The LTC2370-16 has a high speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic while also featuring a daisy-chain mode. The fast 2Msps throughput with no cycle latency makes the LTC2370-16 ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2370-16 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate.
