Dual 8-/10-/12-Bit, High Bandwidth,

Multiplying DACs with Parallel Interface

AD5428/AD5440/AD5447

Data Sheet

FEATURES

GENERAL DESCRIPTION

10 MHz multiplying bandwidth

INL of 0.2ꢀ LSB ꢁ 8 bits

20-lead and 24-lead TSSOP packages

2.ꢀ V to ꢀ.ꢀ V supply operation

10 V reference input

The AD5428/AD5440/AD5447¹are CMOS, 8-, 10-, and 12-bit,

dual-channel, current output digital-to-analog converters (DACs),

respectively. These devices operate from a 2.5 V to 5.5 V power

supply, making them suited to battery-powered and other

applications.

21.3 MSPS update rate

As a result of being manufactured on a CMOS submicron process,

they offer excellent 4-quadrant multiplication characteristics,

with large signal multiplying bandwidths of up to 10 MHz.

Extended temperature range: −40°C to +12ꢀ°C

4-quadrant multiplication

Power-on reset

0.ꢀ μA typical current consumption

Guaranteed monotonic

Readback function

AD7ꢀ28 upgrade (ADꢀ428)

AD7ꢀ47 upgrade (ADꢀ447)

The DACs use data readback, allowing the user to read the

contents of the DAC register via the DB pins. On power-up, the

internal register and latches are filled with 0s, and the DAC

outputs are at zero scale.

The applied external reference input voltage (V_REF) determines

the full-scale output current. An integrated feedback resistor (R_FB)

provides temperature tracking and full-scale voltage output when

combined with an external I-to-V precision amplifier.

APPLICATIONS

Portable battery-powered applications

Waveform generators

Analog processing

The AD5428 is available in a small 20-lead TSSOP package, and

the AD5440/AD5447 DACs are available in small 24-lead TSSOP

packages.

Instrumentation applications

Programmable amplifiers and attenuators

Digitally controlled calibration

Programmable filters and oscillators

Composite video
