2.5 V to 5.5 V, 230 ␮A, Parallel Interface

Dual Voltage-Output 8-/10-/12-Bit DACs

AD5332/AD5333/AD5342/AD5343*

FEATURES

GENERAL DESCRIPTION

AD5332: Dual 8-Bit DAC in 20-Lead TSSOP

AD5333: Dual 10-Bit DAC in 24-Lead TSSOP

AD5342: Dual 12-Bit DAC in 28-Lead TSSOP

AD5343: Dual 12-Bit DAC in 20-Lead TSSOP

Low Power Operation: 230 ␮A @ 3 V, 300 ␮A @ 5 V

via PD Pin

Power-Down to 80 nA @ 3 V, 200 nA @ 5 V

2.5 V to 5.5 V Power Supply

Double-Buffered Input Logic

Guaranteed Monotonic by Design Over All Codes

Buffered/Unbuffered Reference Input Options

Output Range: 0–V_REFor 0–2 V_REF

The AD5332/AD5333/AD5342/AD5343 are dual 8-, 10-, and

12-bit DACs. They operate from a 2.5 V to 5.5 V supply con-

suming just 230 µA at 3 V, and feature a power-down pin, PD

that further reduces the current to 80 nA. These devices incor-

porate an on-chip output buffer that can drive the output to

both supply rails, while the AD5333 and AD5342 allow a choice

of buffered or unbuffered reference input.

The AD5332/AD5333/AD5342/AD5343 have a parallel interface.

CS selects the device and data is loaded into the input registers

on the rising edge of WR.

The GAIN pin on the AD5333 and AD5342 allows the output

range to be set at 0 V to V_REFor 0 V to 2 × V_REF

Power-On Reset to Zero Volts

Simultaneous Update of DAC Outputs via LDAC Pin

Asynchronous CLR Facility

Low Power Parallel Data Interface

On-Chip Rail-to-Rail Output Buffer Ampliﬁers

Temperature Range: –40؇C to +105؇C

Input data to the DACs is double-buffered, allowing simultaneous

update of multiple DACs in a system using the LDAC pin.

An asynchronous CLR input is also provided, which resets the

contents of the Input Register and the DAC Register to all zeros.

These devices also incorporate a power-on reset circuit that ensures

that the DAC output powers on to 0 V and remains there until

valid data is written to the device.

APPLICATIONS

Portable Battery-Powered Instruments

Digital Gain and Offset Adjustment

Programmable Voltage and Current Sources

Programmable Attenuators

The AD5332/AD5333/AD5342/AD5343 are available in Thin

Shrink Small Outline Packages (TSSOP).
