APPLICATIONS

Differential current outputs are provided to support single-

ended or differential applications. The current outputs may be

directly tied to an output resistor to provide two complemen-

tary, single-ended voltage outputs. The output voltage compliance

range is 1.25 V.

PRODUCT DESCRIPTION

The AD9708 is the 8-bit resolution 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, was specifically opti-

mized for the transmit signal path of communication 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 AD9708 offers exceptional ac and dc performance

while supporting update rates up to 125 MSPS.

The AD9708 contains a 1.2 V on-chip reference and reference

control amplifier, which allows the full-scale output current to

be simply set by a single resistor. The AD9708 can be driven by

a variety of external reference voltages. The AD9708’s full-scale

current can be adjusted over a 2 mA to 20 mA range without

any degradation in dynamic performance. Thus, the AD9708

may operate at reduced power levels or be adjusted over a 20 dB

range to provide additional gain ranging capabilities.

The AD9708 is available in 28-lead SOIC and 28-lead TSSOP

packages. It is specified for operation over the industrial tem-

perature range.

The AD9708’s flexible single-supply operating range of +2.7 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 45 mW, without a significant degradation in

performance, by lowering the full-scale current output. In addi-

tion, a power-down mode reduces the standby power dissipa-

tion to approximately 20 mW.

PRODUCT HIGHLIGHTS

1. The AD9708 is a member of the TxDAC product family, which

provides an upward or downward component selection path

based on resolution (8 to 14 bits), performance and cost.

2. Manufactured on a CMOS process, the AD9708 uses a pro-

prietary switching technique that enhances dynamic perfor-

mance well beyond 8- and 10-bit video DACs.

3. On-chip, edge-triggered input CMOS latches readily interface

to +3 V and +5 V CMOS logic families. The AD9708 can

support update rates up to 125 MSPS.

4. A flexible single-supply operating range of +2.7 V to +5.5 V

and a wide full-scale current adjustment span of 2 mA to

20 mA allows the AD9708 to operate at reduced power levels

(i.e., 45 mW) without any degradation in dynamic performance.

The AD9708 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 temperature compensated bandgap reference have been inte-

grated to provide a complete monolithic DAC solution. Flexible

supply options support +3 V and +5 V CMOS logic families.

The AD9708 is a current-output DAC with a nominal full-scale

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

TxDAC is a trademark of Analog Devices, Inc.

*Patent pending.

5. A temperature compensated, 1.20 V bandgap reference is

included on-chip providing a complete DAC solution. An

external reference may be used.

6. The current output(s) of the AD9708 can easily be config-

ured for various single-ended or differential applications.
