GENERAL DESCRIPTION
The AD97401 is a 10-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 communication systems. All of the devices share the same
interface options, small outline package, and pinout, providing
an upward or downward component selection path based
on performance, resolution, and cost. The AD9740 offers
exceptional ac and dc performance while supporting update
rates up to 210 MSPS.
The AD9740’s low power dissipation makes it well suited for
portable and low power applications. Its power dissipation
can be further reduced to 60 mW with a slight degradation in
performance by lowering the full-scale current output. In
addition, a power-down mode reduces the standby power
dissipation to approximately 15 mW. 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
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 AD9740 is the 10-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
210 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 AD9740 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.
