PRODUCT DESCRIPTION

The AD9752 is a 12-bit resolution, wideband, second generation

member of the TxDAC series of high performance, low power

CMOS digital-to-analog-converters (DACs). The TxDAC family,

which consists of pin compatible 8-, 10-, 12-, and 14-bit DACs, is

specifically optimized for the transmit signal path of communica-

tion systems. All of the devices share the same interface options,

small outline package and pinout, thus providing an upward or

downward component selection path based on performance,

resolution and cost. The AD9752 offers exceptional ac and dc

performance while supporting update rates up to 125 MSPS.

The AD9752’s flexible single-supply operating range of 4.5 V to

5.5 V and low power dissipation are well suited for portable and

low power applications. Its power dissipation can be further

reduced to a mere 65 mW, without a significant degradation in

performance, by lowering the full-scale current output. Also, a

power-down mode reduces the standby power dissipation to

approximately 20 mW.

The AD9752 is manufactured on an advanced CMOS process.

A segmented current source architecture is combined with a

proprietary switching technique to reduce spurious components

and enhance dynamic performance. Edge-triggered input latches

and a 1.2 V temperature compensated bandgap reference have

been integrated to provide a complete monolithic DAC solution.

The digital inputs support +2.7 V to +5 V CMOS logic families.

12-Bit, 125 MSPS High Performance

The AD9752 is a current-output DAC with a nominal full-scale

output current of 20 mA and > 100 k output impedance.

Differential current outputs are provided to support single-

ended or differential applications. Matching between the two

current outputs ensures enhanced dynamic performance in a

differential output configuration. The current outputs may be

tied directly to an output resistor to provide two complemen-

tary, single-ended voltage outputs or fed directly into a trans-

former. The output voltage compliance range is 1.25 V.

The on-chip reference and control amplifier are configured for

maximum accuracy and flexibility. The AD9752 can be driven

by the on-chip reference or by a variety of external reference

voltages. The internal control amplifier, which provides a wide

(>10:1) adjustment span, allows the AD9752 full-scale current

to be adjusted over a 2 mA to 20 mA range while maintaining

excellent dynamic performance. Thus, the AD9752 may oper-

ate at reduced power levels or be adjusted over a 20 dB range to

provide additional gain ranging capabilities.

The AD9752 is available in 28-lead SOIC and TSSOP packages.

It is specified for operation over the industrial temperature range.
