AD7265BSUZ-REEL7

AD7265 is a dual, 12-bit, high speed, low power, successive approximation ADC. The device contains two ADCs, each preceded by a 3-channel multiplexer, and a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 30MHz. The conversion process and data acquisition use standard control inputs allowing easy interfacing to microprocessors or DSPs. The input signal is sampled on the falling edge of CS; conversion is also initiated at this point. The conversion time is determined by the SCLK frequency. The part also offers flexible power/throughput rate management when operating in normal mode, because the quiescent current consumption is so low.
