Analog Devices Inc. AD7927BRUZ-REEL

Description
The AD7927 is an 8-channel, 12-bit, 200 kSPS analog-to-digital converter (ADC) with a sequencer. It operates from a single 2.7 V to 5.25 V power supply and features a low noise, wide bandwidth track-and-hold amplifier. The conversion process and data acquisition are controlled using CS and the serial clock signal, allowing the device to easily interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS and the conversion is also initiated at this point. There are no pipeline delays associated with the part.
