APPLICATIONS

DESCRIPTION

The ADS5204 is a dual 10-bit, 40MSPS Analog-to-Digital

Converter (ADC). It simultaneously converts each analog

input signal into a 10-bit, binary coded digital word up to

a maximum sampling rate of 40MSPS per channel. All

digital inputs and outputs are 3.3VTTL/CMOS compat-

ible.

An innovative dual pipeline architecture implemented in

a CMOS process and the 3.3V supply results in very low

power dissipation. In order to provide maximum flexibil-

ity, both top and bottom voltage references can be set

from user-supplied voltages. Alternatively, if no external

references are available, the on-chip internal refer-

ences can be used. Both ADCs share a common refer-

ence to improve offset and gain matching. If external

reference voltage levels are available, the internal refer-

ences can be powered down independently from the

rest of the chip, resulting in even greater power savings.

The ADS5204 also features dual, onboard Programmable

Gain Amplifiers (PGAs) that allow a setting of 0dB to 18dB

to adjust the gain of each set of inputs in order to match

the amplitude of the incoming signal.

The ADS5204 is characterized for operation from –40

°C

to +85

°C and is available in a TQFP-48 package.
