PRODUCT HIGHLIGHTS
1. The AD9204 operates from a single 1.8 V analog power
supply and features a separate digital output driver supply
to accommodate 1.8 V to 3.3 V logic families.
2. The patented sample-and-hold circuit maintains excellent
performance for input frequencies up to 200 MHz and is
designed for low cost, low power, and ease of use.
3. A standard serial port interface supports various product
features and functions, such as data output formatting,
internal clock divider, power-down, DCO/DATA timing
and offset adjustments, and voltage reference modes.
4. The AD9204 is packaged in a 64-lead RoHS compliant
LFCSP that is pin compatible with the AD9268 16-bit
ADC, the AD9251 and AD9258 14-bit ADCs, and the
AD9231 12-bit ADC, enabling a simple migration path
between 10-bit and 16-bit converters sampling from
20 MSPS to 125 MSPS.

GENERAL DESCRIPTION
The AD9204 is a monolithic, dual-channel, 1.8 V supply, 10-bit,
20 MSPS/40 MSPS/65 MSPS/80 MSPS analog-to-digital converter
(ADC). It features a high performance sample-and-hold circuit
and on-chip voltage reference.
The product uses multistage differential pipeline architecture
with output error correction logic to provide 10-bit accuracy at
80 MSPS data rates and to guarantee no missing codes over the
full operating temperature range.
The ADC contains several features designed to maximize
flexibility and minimize system cost, such as programmable
clock and data alignment and programmable digital test pattern
generation. The available digital test patterns include built-in
deterministic and pseudorandom patterns, along with custom
user-defined test patterns entered via the serial port interface (SPI).
AD9204
A differential clock input controls all internal conversion cycles.
An optional duty cycle stabilizer (DCS) compensates for wide
variations in the clock duty cycle while maintaining excellent
overall ADC performance.
The digital output data is presented in offset binary, gray code, or
twos complement format. A data output clock (DCO) is provided
for each ADC channel to ensure proper latch timing with receiving
logic. Both 1.8 V and 3.3 V CMOS levels are supported and output
data can be multiplexed onto a single output bus.
The AD9204 is available in a 64-lead RoHS compliant LFCSP
and is specified over the industrial temperature range (−40°C
to +85°C).
