1 MSPS, Serial 14-Bit SAR ADC AD7485
FEATURES Fast Throughput Rate: 1 MSPS Wide Input Bandwidth: 40 MHz Excellent DC Accuracy Performance Flexible Serial Interface Low Power:
80 mW (Full Power) and 3 mW (NAP Mode) STANDBY Mode: 2 A Max Single 5 V Supply Operation Internal 2.5 V Reference Full-Scale Overrange Indication
GENERAL DESCRIPTION The AD7485 is a 14-bit, high speed, low power, successiveapproximation ADC. The part features a serial interface with throughput rates up to 1 MSPS. The part contains a low noise, wide bandwidth track-and-hold that can handle input frequencies in excess of 40 MHz.
The conversion process is a proprietary algorithmic successiveapproximation technique. The input signal is sampled and a conversion is initiated on the falling edge of the CONVST signal.
