AD7273

FEATURES Throughput rate: 3 MSPS Specified for VDD of 2.35 V to 3.6 V Power consumption 11.4 mW at 3 MSPS with 3 V supplies Wide input bandwidth 70 dB SNR at 1 MHz input frequency Flexible power/serial clock speed management No pipeline delays High speed serial interface SPI®-/QSPI™-/MICROWIRE™-/DSP-compatible Temperature range: −40°C to +125°C Power-down mode: 0.1 μA typ 8-lead TSOT package 8-lead MSOP package GENERAL DESCRIPTION The AD7273/AD7274 are 10-/12-bit, high speed, low power, successive approximation ADCs, respectively. The parts operate from a single 2.35 V to 3.6 V power supply and feature throughput rates of up to 3 MSPS. Each part contains a low noise, wide bandwidth track-and-hold amplifier that can handle input frequencies in excess of 55 MHz. The conversion process and data acquisition are controlled using CS and the serial clock, allowing the devices to interface with microprocessors or DSPs. The input signal is sampled on the falling edge of CS, and the co...
