Overview

All Grades 14-Bit Monotonic Over the Full Temperature Range
Full 4-Quadrant Multiplication
Microprocessor-Compatible with Double Buffered Inputs

Exceptionally Low Gain Temperature Coefficient 0.5ppm/°C typ
Small 20-Pin DIP and Surface Mount Package
Low Output Leakage (<20nA) over the Full Temperature Range

The AD7534 is a 14-bit monolithic CMOS D/A converter which uses thin-film resistors and laser trimming to achieve excellent linearity.

The device is configured to accept right-justified data in two bytes from an 8-bit data bus. Standard Chip Select and Memory Write logic is used to access the DAC. Address lines A0 and A1 control internal register loading and transfer.

A novel low leakage configuration (patent pending) enables the AD7534 to exhibit excellent output leakage current characteristics over the specified temperature range.

The device is fully protected against CMOS "latch up" phenomena and does not require the use of external Schottky diodes or the use of a FET Input op amp. The AD7534 is manufactured using the Linear Compatible CMOS (LC²MOS) process. It is speed compatible with most microprocessors and accepts TTL or CMOS logic level inputs.

Tools & Simulations

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.
