The AD9481 is available in a Pb-free, 44-lead, surface-mount

package (TQFP-44) specified over the industrial temperature

range (−40°C to +85°C).

GENERAL DESCRIPTION

The AD9481 is an 8-bit, monolithic analog-to-digital converter

(ADC) optimized for high speed and low power consumption.

Small in size and easy to use, the product operates at a

250 MSPS conversion rate, with excellent linearity and dynamic

performance over its full operating range.

PRODUCT HIGHLIGHTS

1. Superior linearity. A DNL of 0.35 makes the AD9481

suitable for many instrumentation and measurement

applications

To minimize system cost and power dissipation, the AD9481

includes an internal reference and track-and-hold circuit. The

user only provides a 3.3 V power supply and a differential

encode clock. No external reference or driver components are

required for many applications.

2. Power-down mode. A power-down function may be exercised

to bring total consumption down to 15 mW.

3. De-multiplexed CMOS outputs allow for easy interfacing

with low cost FPGAs and standard logic.

The digital outputs are TTL/CMOS-compatible with an option

of twos complement or binary output format. The output data

bits are provided in an interleaved fashion along with output

clocks that simplifies data capture.
