Overview
The AD664JNZ-UNI is a quad 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features parallel data interfaces and voltage outputs, designed for through-hole mounting in CDIP-SB-28 packages. The component operates within an industrial temperature range of -40°C to +85°C, utilizing a single 5V digital supply and analog supplies ranging from 11.4V to 16.5V. This specific UNI suffix variant indicates a non-RoHS compliant construction, typically associated with legacy or specialized procurement channels distinct from standard commercial RoHS-compliant versions.
Feature Summary
- Quad 12-bit resolution architecture providing four independent DAC channels
- Parallel interface compatibility for direct microprocessor connection
- Voltage output type suitable for general-purpose signal generation
- Through-hole CDIP-SB-28 package design for robust board integration
Applications
- Industrial process control systems requiring multi-channel signal generation
- Test and measurement equipment needing precise analog waveform synthesis
- Legacy aerospace and defense instrumentation maintaining older hardware standards
Procurement Notes
Verify the 'UNI' suffix designation carefully against current RoHS directives, as this variant often denotes non-compliant lead content compared to modern equivalents. Confirm availability status directly with authorized distributors, as this part may be subject to limited stock or end-of-life restrictions. Ensure that the through-hole package dimensions match existing PCB footprints before ordering.
Selection Notes
Select this component when a quad 12-bit DAC with parallel interfacing is required for through-hole assembly. Compare DNL and INL specifications against system accuracy requirements; typical values are +/- 1 LSB. Ensure the power supply rails can accommodate the specified 11.4V to 16.5V analog range and 5V digital logic levels. Consider thermal dissipation capabilities within the CDIP package for high-density designs.
Part Context
This device belongs to the AD664 family of high-performance monolithic DACs. The AD664 series is known for its speed and accuracy in multi-channel applications. The 'JNZ' indicates a ceramic DIP package with a specific temperature grade, while 'UNI' distinguishes it from standard RoHS-compliant variants like the AD664JPZ or AD664BJ, which may have different environmental certifications but similar electrical characteristics.
Replacement Considerations
The AD664JPZ and AD664BJ are electrically similar quad 12-bit DACs from the same family. However, these alternatives typically feature SMD/PLCC packaging and RoHS compliance. Verify pinout compatibility and package footprint differences before substituting. The AD664SD-UNI offers a similar through-hole option but in a smaller SB-CDIP-28 package.
