AD5766/AD5767

Data Sheet

voltage as low as −20 V or a maximum output voltage of up to

+14 V. Each of the 16 channels can be monitored with an

integrated output voltage multiplexer.

FEATURES

Complete 16-channel, 12-bit/16-bit DACs

8 software-programmable output ranges: −20 V to 0 V,

−16 V to 0 V, −10 V to 0 V, −10 V to +6 V, −12 V to +14 V,

−16 V to +10 V, ±± V and ±10 V

Integrated DAC output buffers with ±20 mA output current

capability

4 mm × 4 mm WLCSP package and 40-lead LFCSP package

Integrated reference buffers

2 dither signal input pins

The AD5766/AD5767 have integrated output buffers that can

sink or source up to 20 mA. In conjunction with these buffers, a

low frequency signal can be superimposed onto each DAC output

via dedicated dither pins. These dedicated dither pins simplify

the system design by reducing the number of external components

required for a similar external implementation, like operational

amplifiers or resistors. The reduction of external components

makes the AD5766/AD5767 suitable for indium phosphide Mach

Zehnder modulator (InP MZM) biasing applications.

Channel monitoring multiplexer

1.8 V logic compatibility

Temperature range: −40°C to +10±°C

The devices incorporate a power-on reset (POR) circuit that

ensures that the DAC outputs are clamped to ground on power

up and remain at this level until the output range of the DAC is

configured. The outputs of all DACs are updated through register

configuration, with the added functionality of user-selectable

DAC channels to be simultaneously updated.

APPLICATIONS

Mach Zehnder modulator bias control

Optical networking

Instrumentation

Industrial automation

Data acquisition systems

Analog output modules

The AD5766/AD5767 use a versatile 4-wire serial interface that

operates at clock rates of up to 50 MHz for write mode and is

compatible with serial peripheral interface (SPI), QSPI™,

MICROWIRE™, and DSP interface standards. The AD5766/

AD5767 also contain a V_LOGICpin intended for 1.8 V/3.3 V/5 V

logic.

GENERAL DESCRIPTION

The AD5766/AD5767 are 16-channel, 16-bit/12-bit, voltage output

denseDAC® digital-to-analog converters (DACs).

The DACs generate output voltage ranges from an external 2.5 V

reference. Depending on the voltage range selected, the midpoint

of the output span can be adjusted, allowing a minimum output

The AD5766/AD5767 are available in a 4 mm × 4 mm WLCSP

package and a 40-lead LFCSP package. The AD5766/AD5767

operate at a temperature range of −40°C to +105°C.
