PRODUCT DESCRIPTION
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.
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.
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.
PRODUCT HIGHLIGHTS
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.
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.
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.
