ANALOG DEVICES LTC2378IMS-16#PBF Analogue to Digital Converter, 16 bit, 1 MSPS, Differential, Single Ended, Serial, SPI, Single

LTC2378IMS-16#PBF is a low noise, low power, high speed 16bit successive approximation register (SAR) ADC. Operating from a 2.5V supply, the LTC2378-16 has a ±VREF fully differential input range with VREF ranging from 2.5V to 5.1V. The LTC2378-16 consumes only 13.5mW and achieves ±0.5LSB INL maximum, no missing codes at 16 bits with 97dB SNR. The LTC2378-16 has a high-speed SPI-compatible serial interface that supports 1.8V, 2.5V, 3.3V, and 5V logic while also featuring a daisy-chain mode. The fast 1Msps throughput with no cycle latency makes the LTC2378-16 ideally suited for a wide variety of high-speed applications. An internal oscillator sets the conversion time, easing external timing considerations. Applications include medical imaging, high-speed data acquisition, portable or compact instrumentation, industrial process control, low-power battery-operated instrumentation, and ATE.
