Overview
The AD664JP is a quad 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features a parallel interface and voltage output type, housed in a PLCC-44 surface-mount package. The device operates with analog supply voltages ranging from 11.4 V to 16.5 V and a fixed 5 V digital supply. Key performance metrics include a settling time of 10 µs, differential nonlinearity (DNL) of ±0.75 LSB, and integral nonlinearity (INL) of ±0.5 LSB. It functions within a temperature range of -40°C to +85°C.
Feature Summary
- Quad 12-bit resolution with R-2R architecture
- Parallel data interface for high-speed updates
- Low DNL (+/- 0.75 LSB) and INL (+/- 0.5 LSB)
- 10 µs settling time for buffered voltage outputs
Applications
- High-resolution waveform generation systems
- Precision test and measurement equipment
- Industrial process control loops requiring multi-channel analog output
Procurement Notes
Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm RoHS compliance status as indicated on the specific datasheet revision. Check for moisture sensitivity level requirements during storage and handling. Ensure the PLCC-44 footprint matches the target PCB design constraints.
Selection Notes
Select this model when four independent 12-bit voltage outputs are required in a single package. Compare DNL and INL specifications against application accuracy needs. Verify that the parallel interface timing aligns with the host controller capabilities. Consider the PLCC-44 package availability if surface mount assembly is preferred over through-hole alternatives.
Part Context
The AD664 belongs to the AD664 series of monolithic DACs. Other variants in the family include the AD664BJ and AD664BD-BIP, which differ in packaging (CDIP vs PLCC) and specific linearity grades. The AD664JP specifically denotes the plastic leaded chip carrier package version with standard military-grade temperature ratings.
Replacement Considerations
The AD664BJ offers similar electrical characteristics but may have different linearity specs (±1 LSB). The AD664BD-BIP provides a through-hole CDIP option. Verify pin compatibility and thermal management requirements before substituting.
