Part Details
- All grades 14-bit monotonic over the full temperature range
- Low cost, 14-bit upgrade for 12-bit systems
- 14-bit parallel load with double buffered inputs
- Small 24-pin, 0.30” DIP and SOIC
- Low output leakage (<20 nA) over the full temperature range
The AD7538 is a 14-bit monolithic CMOS digital-to-analog converter (DAC) that uses laser trimmed thin-film resistors to achieve excellent linearity.
The DAC is loaded by a single 14-bit wide word using standard chip select and memory write logic. Double buffering, which is optional using LDAC, allows simultaneous updates in a system containing multiple AD7538s.
A novel low leakage configuration enables the AD7538 to exhibit excellent output leakage current characteristics over the specified temperature range.
The AD7538 is manufactured using the linear-compatible CMOS (LC2MOS) process. It is speed compatible with most microprocessors and accepts TTL or CMOS logic level inputs.

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.
