GENERAL DESCRIPTION
The AD9744 is a 14-bit resolution, wideband, third generation
member of the TxDAC series of high performance, low power
CMOS digital-to-analog converters (DACs). The TxDAC family,
consisting of pin compatible 8-, 10-, 12-, and 14-bit DACs, is
specifically optimized for the transmit signal path of communi-
cation systems. All of the devices share the same interface options,
small outline package, and pinout, providing an upward or down-
ward component selection path based on performance, resolution,
and cost. The AD9744 offers exceptional ac and dc performance
while supporting update rates up to 165 MSPS.
The AD9744’s low power dissipation makes it well suited for
portable and low power applications. Its power dissipation can
be further reduced to a mere 60 mW with a slight degradation
in performance by lowering the full-scale current output. Also,
a power-down mode reduces the standby power dissipation to
approximately 15 mW. A segmented current source architec-
ture 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 compen-
sated band gap reference have been integrated to provide a
complete monolithic DAC solution. The digital inputs support
3 V CMOS logic families.
PRODUCT HIGHLIGHTS
1. The AD9744 is the 14-bit member of the pin compatible
TxDAC family, which offers excellent INL and DNL
performance.
2. Data input supports twos complement or straight binary
data coding.
3. High speed, single-ended CMOS clock input supports
165 MSPS conversion rate.
4. Low power: Complete CMOS DAC function operates on
135 mW from a 2.7 V to 3.6 V single supply. The DAC
full-scale current can be reduced for lower power operation,
and a sleep mode is provided for low power idle periods.
5. On-chip voltage reference: The AD9744 includes a 1.2 V
temperature compensated band gap voltage reference.
6. Industry-standard 28-lead SOIC, 28-lead TSSOP, and 32-lead
LFCSP packages.
