Overview
The AD664TD-UNI is a quad 12-bit digital-to-analog converter (DAC) from the Analog Devices AD664 series. It features a parallel interface and voltage output in a 28-pin CDIP-SB package. The device operates with analog supply voltages ranging from +/- 11.4 V to +/- 16.5 V and a 5 V digital supply. Key electrical parameters include a settling time of 10 µs, differential nonlinearity (DNL) of +/- 0.5 LSB, and integral nonlinearity (INL) of +/- 0.25 LSB. The component is designed for through-hole mounting and supports an operating temperature range from -40°C to +85°C.
Feature Summary
- Quad 12-bit resolution with R-2R architecture
- Parallel data interface with buffered voltage outputs
- High precision: +/- 0.25 LSB INL and +/- 0.5 LSB DNL
- Wide analog supply range: +/- 11.4 V to +/- 16.5 V
Applications
- Precision instrumentation systems requiring multi-channel DAC conversion
- Industrial control applications utilizing through-hole mounting
- Test and measurement equipment needing low nonlinear error performance
Procurement Notes
Verify the specific suffix 'UNI' against official Analog Devices documentation to confirm exact binning or qualification status, as suffixes can indicate variations in testing or packaging not always evident in general listings. Confirm RoHS compliance status directly with the manufacturer, as legacy parts may have different environmental declarations than current equivalents.
Selection Notes
Select this component when a quad 12-bit DAC with parallel interface and high linearity is required. Ensure the design accommodates the +/- 11.4 V to +/- 16.5 V analog supply rails and 5 V digital logic levels. The 28-CDIP package requires through-hole PCB layout considerations. Verify that the 10 µs settling time meets the system's update rate requirements.
Part Context
The AD664TD-UNI belongs to the AD664 family of quad DACs. This family is characterized by its use of R-2R ladder architecture and buffered outputs. The 'TD' prefix typically denotes military or extended temperature grade variants in Analog Devices nomenclature, while 'UNI' may refer to a specific unit type or qualification level within that grade. It serves as a high-precision alternative to lower-resolution or single-channel DAC solutions in complex signal processing chains.
Replacement Considerations
Publicly confirmed substitute part numbers for the AD664TD-UNI are not available in the provided source material. Users should consult Analog Devices for current equivalent offerings or verify pin-compatible alternatives with matching electrical specifications.
