ADI LTC2372HUH-16#PBF

The LTC2372 - 16 is a low noise, high speed, 8 - channel 16 - bit successive approximation register (SAR) ADC. Operating from a single 5V supply, the LTC2372 - 16 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 - 16 achieves ±1LSB INL (maximum) in all input ranges, no missing codes at 16 - bits and 96dB (fully differential)/93.5dB (pseudo - differential) SNR (typical). The LTC2372 - 16 has an onboard low drift (20ppm/°C max) 2.048V temperature - compensated reference and a single - shot capable reference buffer. The LTC2372 - 16 also has a high speed SPI - compatible serial interface that supports 1.8V, 2.5V, 3.3V and 5V logic through which a sequencer with a depth of 16 may be programmed. An internal oscillator sets the conversion time, easing external timing considerations. The LTC2372 - 16 dissipates only 27mW 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 LTC2372 - 16 to 300μW for further power savings during inactive periods.
