LTC2373-16 - 16-Bit, 1Msps, 8-Channel SAR ADC with 96dB SNR

The LTC®2373-16 is a low noise, high speed, 8-channel 16-bit successive approximation register (SAR) ADC. Operating from a single 5V supply, the LTC2373-16 has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential, pseudo-differential unipolar and pseudo-differential bipolar analog input ranges. The LTC2373-16 achieves ±1LSB INL (maximum) in all input ranges, no missing codes at 16-bits and 96dB (fully differential)/ 93.4dB (pseudo-differential) SNR (typical).

The LTC2373-16 has an onboard low drift (20ppm/°C max) 2.048V temperature-compensated reference and a singleshot capable reference buffer. The LTC2373-16 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 LTC2373-16 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 LTC2373-16 to 300μW for further power savings during inactive periods.
