LTC2372-18 Datasheet 8-Channel SAR ADC

Manufacturer: Linear Technology (now Analog Devices)

General Description

The LTC®2372-18 is a low noise, high speed, 8-channel 18-bit successive approximation register (SAR) ADC.

Operating from a single 5V supply, the LTC2372-18 has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges.

The LTC2372-18 achieves ±2.75LSB INL (maximum) in all input ranges, no missing codes at 18-bits and 100dB (fully differential)/ 95dB (pseudo-differential) SNR (typical).

Overview

LTC2372-18 18-Bit, 500ksps, 8-Channel SAR ADC with 100dB SNR.
