LTC2376CMS-18#PBF

LTC®2376-18 is a low noise, low power, high speed 18bit successive approximation register (SAR) ADC. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2376-18 automatically powers down between conversions, leading to reduced power dissipation that scales with the sampling rate. The LTC2376-18 features a unique digital gain compression (DGC) function, which eliminates the driver amplifier’s negative supply while preserving the full resolution of the ADC. When enabled, the ADC performs a digital scaling function that maps zero-scale code from 0V to 0.1 • VREF and full-scale code from VREF to 0.9 • VREF. Application includes medical imaging, high speed data acquisition, portable or compact instrumentation, industrial process control, low power battery-operated instrumentation, ATE.
