PRODUCT DESCRIPTION

PRODUCT HIGHLIGHTS

The AD9201 is a complete dual channel, 20 MSPS, 10-bit

CMOS ADC. The AD9201 is optimized specifically for applica-

tions where close matching between two ADCs is required (e.g.,

I/Q channels in communications applications). The 20 MHz

sampling rate and wide input bandwidth will cover both narrow-

band and spread-spectrum channels. The AD9201 integrates two

10-bit, 20 MSPS ADCs, two input buffer amplifiers, an internal

voltage reference and multiplexed digital output buffers.

1. Dual 10-Bit, 20 MSPS ADCs

A pair of high performance 20 MSPS ADCs that are opti-

mized for spurious free dynamic performance are provided for

encoding of I and Q or diversity channel information.

2. Low Power

Complete CMOS Dual ADC function consumes a low

215 mW on a single supply (on 3 V supply). The AD9201

operates on supply voltages from 2.7 V to 5.5 V.

Each ADC incorporates a simultaneous sampling sample-and-

hold amplifier at its input. The analog inputs are buffered; no

external input buffer op amp will be required in most applica-

tions. The ADCs are implemented using a multistage pipeline

architecture that offers accurate performance and guarantees no

missing codes. The outputs of the ADCs are ported to a multi-

plexed digital output buffer.

3. On-Chip Voltage Reference

The AD9201 includes an on-chip compensated bandgap

voltage reference pin programmable for 1 V or 2 V.

4. On-chip analog input buffers eliminate the need for external

op amps in most applications.

5. Single 10-Bit Digital Output Bus

The AD9201 ADC outputs are interleaved onto a single

output bus saving board space and digital pin count.

The AD9201 is manufactured on an advanced low cost CMOS

process, operates from a single supply from 2.7 V to 5.5 V, and

consumes 215 mW of power (on 3 V supply). The AD9201 input

structure accepts either single-ended or differential signals,

providing excellent dynamic performance up to and beyond

its 10 MHz Nyquist input frequencies.

6. Small Package

The AD9201 offers the complete integrated function in a

compact 28-lead SSOP package.

7. Product Family

The AD9201 dual ADC is pin compatible with a dual 8-bit

ADC (AD9281) and has a companion dual DAC product,

the AD9761 dual DAC.
