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...
