GENERAL DESCRIPTION

The AD9203 is a monolithic low power, single supply, 10-bit,

40 MSPS analog-to-digital converter, with an on-chip voltage

reference. The AD9203 uses a multistage differential pipeline

architecture and guarantees no missing codes over the full

operating temperature range. Its input range may be adjusted

between 1 V and 2 V p-p.

The AD9203 can operate with a supply range from 2.7 V to 3.6

V, an attractive option for low power operation in high-speed

portable applications.

The AD9203 is specified over industrial (−40°C to +85°C)

temperature ranges and is available in a 28-lead TSSOP package.

The AD9203 has an onboard programmable reference. An

external reference can also be chosen to suit the dc accuracy

and temperature drift requirements of an application.

PRODUCT HIGHLIGHTS

Low Power—The AD9203 consumes 74 mW on a 3 V supply

operating at 40 MSPS. In standby mode, power is reduced to

0.65 mW.

High Performance—Maintains better than 9.55 ENOB at 40

MSPS input signal from dc to Nyquist.

Ver y Small Package—The AD9203 is available in a 28-lead

TSSOP.

Programmable Power—The AD9203 power can be further

reduced by using an external resistor at lower sample rates.

Built-In Clamp Function—Allows dc restoration of video

signals.

An external resistor can be used to reduce power consumption

when operating at lower sampling rates. This yields power

savings for users who do not require the maximum sample rate.

This feature is especially useful at sample rates far below 40

MSPS. Excellent performance is still achieved at reduced power.

For example, 9.7 ENOB performance may be realized with only

17 mW of power, using a 5 MHz clock.

A single clock input is used to control all internal conversion

cycles. The digital output data is presented in straight binary or

twos complementary output format by using the DFS pin. An
