Overview
The AD664SD-BIP is a quad 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features four independent channels with parallel data interfaces and buffered voltage outputs. The device operates within an analog supply range of ±11.4V to ±16.5V and a digital supply of 5V. It utilizes an R-2R architecture and achieves a typical settling time of 10µs. Non-linearity specifications include integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.5 LSB. The component is housed in a 28-pin CDIP package designed for through-hole mounting, supporting industrial temperature ranges from -40°C to +85°C.
Feature Summary
- Quad 12-bit resolution with parallel interface
- Buffered voltage outputs with ±0.5 LSB INL/DNL
- 10µs settling time using R-2R architecture
- 28-CDIP through-hole package
Applications
- Industrial process control systems
- Test and measurement instrumentation
- Military and aerospace signal generation
Procurement Notes
Verify RoHS compliance status as the component may not meet current environmental directives. Confirm availability through authorized distributors, as stock levels are often limited. Ensure proper handling procedures for ceramic dual in-line packages during assembly to prevent mechanical stress on the leads.
Selection Notes
Select this part when multiple isolated analog outputs are required from a single digital source. The buffered output stage simplifies driving capacitive loads without external amplifiers. Verify that the system logic levels match the 5V digital supply requirement and that the PCB layout accommodates the 28-lead ceramic footprint.
Part Context
This component belongs to the AD664 family of high-performance DACs. It shares architectural similarities with the AD664BD-BIP but differs in specific performance grades and packaging options. The SD suffix typically denotes a specific military or enhanced reliability grade variant within the broader product line.
Replacement Considerations
The AD664BD-BIP is a parameter-equivalent alternative within the same series. Verify pinout compatibility and thermal characteristics before substitution. Other variants like the AD664JPZ offer surface-mount options but require different PCB footprints.
