AD664BD-BIP

Overview

The AD664BD-BIP is a quad 12-bit digital-to-analog converter (DAC) from Analog Devices, housed in a 28-CDIP package. It utilizes an R-2R architecture with buffered voltage outputs and parallel data interfaces. The device operates on dual analog supplies ranging from ±11.4 V to ±16.5 V and a single 5 V digital supply. Key electrical specifications include a settling time of 10 µs, integral nonlinearity (INL) of ±0.5 LSB, and differential nonlinearity (DNL) of ±0.5 LSB. It supports an operating temperature range of -40°C to +85°C.

Feature Summary

• Quad 12-bit resolution with R-2R architecture
• Buffered voltage outputs for direct drive capability
• ±0.5 LSB INL and DNL performance
• 10 µs settling time

Applications

• Industrial process control systems
• Precision instrumentation
• Test and measurement equipment

Procurement Notes

Verify component authenticity through authorized channels due to potential availability constraints. Confirm RoHS3 compliance status as indicated in official documentation. Check for specific ordering suffixes that may affect pinout or performance characteristics relative to the base AD664 model.

Selection Notes

Select this part for applications requiring four independent 12-bit DAC channels in a through-hole package. Ensure power supply rails match the ±11.4 V to ±16.5 V requirement. Consider the 28-CDIP footprint for PCB layout compatibility. Verify thermal management needs within the -40°C to +85°C operational range.

Part Context

Part of the AD664 family of high-speed, low-power quad DACs. The BD suffix typically denotes military-grade temperature range and enhanced reliability specifications compared to commercial variants. This component serves as a legacy solution for precision analog output generation in established industrial designs.

Replacement Considerations

AD664BD-UNI is listed as a parameter-equivalent substitute. Verify pin compatibility and specification alignment before substitution.
