Instrumentation

segmented current source architecture is combined with a

proprietary switching technique to reduce spurious components

and enhance dynamic performance. Matching between the two

current outputs ensures enhanced dynamic performance in a

differential output conﬁguration.The differential current outputs

may be fed into a transformer or a differential op amp topology

to obtain a single-ended output voltage using an appropriate

resistive load.

GENERAL DESCRIPTION

The AD9772A is a single-supply, oversampling, 14-bit digi-

tal-to-analog converter (DAC) optimized for baseband or IF

waveform reconstruction applications requiring exceptional

dynamic range. Manufactured on an advanced CMOS pro-

cess, it integrates a complete, low distortion 14-bit DAC with

The on-chip band gap reference and control ampliﬁer are con-

ﬁgured for maximum accuracy and ﬂexibility.The AD9772A

can be driven by the on-chip reference or by a variety of external

reference voltages.The full-scale current of the AD9772A can be

adjusted over a 2 mA to 20 mA range, thus providing additional

gain ranging capabilities.

a 2

 digital interpolation ﬁlter and clock multiplier.The on-

chip PLL clock multiplier provides all the necessary clocks

for the digital ﬁlter and the 14-bit DAC. A ﬂexible differential

clock input allows for a single-ended or differential clock

driver for optimum jitter performance.

The AD9772A is available in a 48-lead LQFP package and is

speciﬁed for operation over the industrial temperature range of

–40°C to +85°C.

For baseband applications, the 2 digital interpolation ﬁlter

provides a low-pass response, thus providing as much as a

threefold reduction in the complexity of the analog reconstruc-

tion ﬁlter. It does so by multiplying the input data rate by a

factor of 2 while suppressing the original upper in-band image

by more than 73 dB. For direct IF applications, the 2 digital

interpolation ﬁlter response can be reconﬁgured to select the

upper in-band image (i.e., high-pass response) while suppress-

ing the original baseband image. To increase the signal level of

the higher IF images and their pass-band ﬂatness in direct IF

applications, the AD9772A also features a zero-stufﬁng op-

tion in which the data following the 2 interpolation ﬁlter is

upsampled by a factor of 2 by inserting midscale data samples.

PRODUCT HIGHLIGHTS

1. A ﬂexible, low power 2 interpolation ﬁlter supporting recon-

struction bandwidths of up to 67.5 MHz can be conﬁgured

for a low- or high-pass response with 73 dB of image rejection

for traditional baseband or direct IF applications.

2. A zero-stufﬁng option enhances direct IF applications.

3. A low glitch, fast settling 14-bit DAC provides exceptional

dynamic range for both baseband and direct IF waveform

reconstruction applications.

4. The AD9772A digital interface, consisting of edge-triggered

latches and a ﬂexible differential or single-ended clock input,

can support input data rates up to 160 MSPS.

The AD9772A can reconstruct full-scale waveforms with band-

widths as high as 67.5 MHz while operating at an input data

rate of 160 MSPS.The 14-bit DAC provides differential current

outputs to support differential or single-ended applications.

5. On-chip PLL clock multiplier generates all of the internal high

speed clocks required by the interpolation ﬁlter and DAC.

REV.B

6. The current output(s) of the AD9772A can easily be conﬁgured

for various single-ended or differential circuit topologies.
