LINEAR TECHNOLOGY  LTC2373CUH-18#PBF  模数转换器, 18 bit, 1 MSPS, 单, 4.75 V, 5.25 V, QFN

The is a low noise, high speed successive approximation register Analog-to-digital Converter ADC. Operating from a single 5V supply, the ADC has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges. The ADC achieves ±2.75LSB INL in all input ranges, no missing codes at 18-bit and 100dB fully differential/95dB pseudo-differential SNR. The ADC has an onboard low drift 2.048V temperature-compensated reference and a single-shot capable reference buffer. An internal oscillator sets the conversion time, easing external timing considerations. The ADC dissipates only 40mW 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 ADC to 300µW for further power savings during inactive periods.
