GENERAL DESCRIPTION

These parts use advanced design techniques to achieve very low

power dissipation at high throughput rates. They also feature

flexible power management options. An on-chip control register

allows the user to set up different operating conditions,

including analog input range and configuration, output coding,

power management, and channel sequencing.

The AD7933/AD7934 are 12-bit and 10-bit, high speed, low

power, successive approximation (SAR) ADCs. The parts

operate from a single 2.7 V to 5.25 V power supply and feature

throughput rates to 1.5 MSPS. The parts contain a low noise,

wide bandwidth, differential track-and-hold amplifier that can

handle input frequencies up to 20 MHz.

The AD7933/AD7934 feature 4 analog input channels with a

channel sequencer to allow a consecutive sequence of channels

to be converted on. These parts can accept either single-ended,

fully differential, or pseudo-differential analog inputs.

PRODUCT HIGHLIGHTS

1. High throughput with low power consumption.

2. Four analog inputs with a channel sequencer.

3. Accurate on-chip 2.5 V reference.

4. Software configurable analog inputs. Single-ended, pseudo-

differential, or fully differential analog inputs that are

software selectable.

5. Single-supply operation with V_DRIVEfunction. The V_DRIVE

function allows the parallel interface to connect directly to

The conversion process and data acquisition are controlled

using standard control inputs, which allows for easy interfacing

to microprocessors and DSPs. The input signal is sampled on

the falling edge of

and the conversion is also initiated

CONVST

at this point.

3 V, or 5 V processor systems independent of V_DD

6. No pipeline delay.

The AD7933/AD7934 has an accurate on-chip 2.5 V reference

that can be used as the reference source for the analog-to-digital

conversion. Alternatively, this pin can be overdriven to provide

an external reference.

7. Accurate control of the sampling instant via a

CONVST

input and once off conversion control.
