The AD5450 / AD5451 / AD5452 / AD5453 are CMOS 8-/10-/12-/14-bit 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 several applications, including battery-powered applications.

As a result of manufacture on a CMOS submicron process, these DACs offer excellent 4-quadrant multiplication characteristics of up to 12 MHz.

These DACs use a double-buffered, 3-wire serial interface that is compatible with SPI®, QSPI, MICROWIRE, and most DSP interface standards. Upon power-up, the internal shift register and latches are filled with 0s, and the DAC output is at zero scale.

The applied external reference input voltage (VREF) determines the full-scale output current. These parts can handle ±10 V inputs on the reference, despite operating from a single-supply power supply of 2.5 V to 5.5 V. An integrated feedback resistor (RFB) provides temperature tracking and full-scale voltage output when combined with an external current-to-voltage precision amplifier.

The AD5450 / AD5451 / AD5452 / AD5453 DACs are available in small 8-lead TSOT, and the AD5452 / AD5453 are also available in MSOP packages. The AD5453 also comes in 8-lead LFSCP.

Precision DAC Error Budget Tool

The Precision DAC Error Budget Tool is a web application that calculates the DC Accuracy of precision DAC signal chains. It shows how the static errors accumulate throughout your signal chain to quickly evaluate the design tradeoffs. Calculations include the DC errors introduced by Voltage References, Operation Amplifiers and Precision DACs.

EVAL-AD5453

AD5453 Evaluation Board

Product Details

The evaluation board for the AD5453 contains a SDP connection and software which allows the AD5453 to be controlled from an SDP board.

The SDP controller board is a separate list item in the ordering guide below (EVAL-SDP-CS1Z). If you have not previously purchased an SDP controller board, please do so to ensure a full evaluation setup.

This evaluation board can be used to evaluate the AD5450, AD5451 and AD5452.
