The AD5424/AD5433/AD54451 are CMOS 8-, 10- and 12-bit

Current output digital-to-analog converters (DACs), respectively. Digital to Analog Converter AD5445YCPZ

The operating voltage of these devices varies from 2.5 V to 5.5 V,

make them suitable for battery powered applications and the AD5445YCPZ digital-to-analog converter

many other applications. These DACs utilize data readback,

Allows the user to read the contents of the DAC register

DB pin. At power-up, the internal registers and latches are

Filled with 0, the DAC output is zero scale.

Due to the use of CMOS sub-micron process manufacturing,

They provide good four-quadrant multiplication characteristics,

with large signal multiplication bandwidth up to 10 MHz.

The applied external reference input voltage (VREF) determines

full output current. Integrated Feedback Resistor (RFB)

Provides temperature tracking and full-scale voltage output digital-to-analog converter AD5445YCPZ

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

AD5445YCPZ digital-to-analog converters and these devices are an upgrade from the AD5424/AD5433/

AD5445 in terms of multiplying bandwidth performance, they have a

Locks the interface and cannot be used in transparent mode.

The AD5424 is available in a small, 20-lead LFCSP and a small,

16 turn-on TSSOP, AD5433 and AD5445 DACs available

In a small, 20-lead LFCSP and a small, 20-lead TSSOP.

Assuming the DAC switches are driven by true broadband

Low impedance sources (VIN and AGND), they resolve quickly.

Therefore, the rotation rate and settling time of the voltage

The switching DAC circuit is largely determined by the output op

In order to obtain the minimum settling time under this configuration, it

Is it important to minimize the capacitance of the VREF node (voltage)

output node of the DAC). This is done by using

Low input capacitance buffer amplifier and careful board design.

Most single-supply circuits have ground as part of the analog circuit

signal range, which in turn requires an amplifier that can handle

rail-to-rail signal. Single supply has great range

Amplifiers are available from analog devices.

Parallel interface

Data is loaded into the AD5424/AD5433/AD5445 in this format

8-bit, 10-bit or 12-bit parallel word. Control lines CS and R/W

Allows data to be written or read from the DAC register. One

When a write event occurs, CS and R/W are brought low, data

The available data rows fill the shift register, and rise

Edge c latches data and transfers the latched data word

to the DAC register. Therefore, the DAC pins are opaque

The write sequence must consist of falling and rising edges on CS

Make sure the data is loaded into the DAC register and its simulation program

The equivalent is reflected on the DAC output.

A read event occurs when R/W is high and CS is high

belt low. New data is loaded back from the DAC register

input into a register and output to a data line where it can be read

Return to the controller for verification or diagnostics.
