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 conversion is also initiated at this
point. The conversion rate is determined by the SCLK. There
are no pipeline delays associated with these parts.
The AD7273/AD7274 use advanced design techniques to
achieve very low power dissipation at high throughput rates.
The reference for the parts is applied externally and can be in
the range of 1.4 V to VDD. This allows the widest dynamic input
range to the ADC.
