Микросхемы и комплектующие LTC2374IUH-16#PBF

АЦП , 16 бит, 1.6 Мвыборок/с, Дифференциальный, Псевдо-дифференциальный, Несимметричный, SPI

The LTC2374IUH-16#PBF from Linear Technology is a 16bit, 1.6Msps, 8-channel SAR ADC with 96dB SNR in 32 pin QFN package. This low noise, high speed successive approximation register (SAR) ADC operates from a single 5V supply. The LTC2374-16 has a highly configurable, low crosstalk 8-channel input multiplexer, supporting fully differential (±4.096V), pseudo-differential unipolar (0V to 4.096V) & pseudo-differential bipolar (±2.048V) analogue input ranges. The LTC2374-16 achieves ±1LSB INL (maximum) in all input ranges and 96dB (fully differential)/93dB (pseudo-differential) SNR (typical). It has an onboard low drift (20ppm/°C max), 2.048V temperature compensated reference and single shot capable reference buffer. The LTC2374-16 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. It is used in programmable logic controllers, high speed data acquisition and ATE.
