GENERAL DESCRIPTION

The AD7476/AD7477/AD74781

are, respectively, 12-bit, 10-bit,

and 8-bit, high speed, low power, successive approximation

ADCs. The parts operate from a single 2.35 V to 5.25 V power

supply and feature throughput rates up to 1 MSPS. Each part

contains a low noise, wide bandwidth track-and-hold amplifier

that can handle input frequencies in excess of 6 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 initiated at this

point. There are no pipeline delays associated with these parts.

The AD7476/AD7477/AD7478 use advanced design techniques

to achieve very low power dissipation at high throughput rates.

The reference for the parts is taken internally from VDD. This

allows the widest dynamic input range to the ADC. Thus, the

analog input range for the parts are 0 V to VDD. The conversion

rate is determined by the SCLK.
