Overview

The LTC2338CMS-18#PBF is a low noise, high speed 18-bit successive approximation register (SAR) ADC with fully differential inputs. Operating from a single 5V supply, the LTC2338CMS-18#PBF has a ±10.24V true bipolar input range, making it ideal for high voltage applications which require a wide dynamic range. The LTC2338CMS-18#PBF achieves ±4LSB INL maximum, no missing codes at 18-bits with 100dB SNR.

The LTC2338CMS-18#PBF has an on-board single-shot capable reference buffer and low drift (20ppm/°C max) 2.048V temperature compensated reference. The LTC2338CMS-18#PBF also 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 1Msps throughput with no cycle latency makes the LTC2338CMS-18#PBF ideally suited for a wide variety of high speed applications. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2338CMS-18#PBF dissipates only 50mW and automatically naps between conversions, leading to reduced power dissipation that scales with the sampling rate. A sleep mode is also provided to reduce the power consumption of the LTC2338CMS-18#PBF to 300μW for further power savings during inactive periods.
