AD664TD-BIP

Overview

The AD664TD-BIP is a high-speed, quad 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It integrates four independent current-output channels within a single integrated circuit, designed for applications requiring precise multi-channel signal generation. The device utilizes an R-2R resistor ladder architecture to achieve its resolution and operates with a parallel data interface for input control. Electrical specifications include a typical settling time of 10 microseconds and output types that are voltage buffered. The component supports dual analog supply voltages ranging from ±11.4 V to ±16.5 V and requires a standard 5 V digital supply. It is housed in a 28-lead ceramic dual in-line package (CDIP), suitable for through-hole mounting in robust electronic systems.

Feature Summary

• Quad 12-bit resolution with R-2R architecture providing ±0.5 LSB DNL and ±0.25 LSB INL
• Fast settling time of 10 µs for rapid signal updates across all four channels
• Parallel data interface compatible with standard logic families
• Voltage-buffered outputs simplifying external circuit design

Applications

• Multi-channel waveform generation systems
• Precision test and measurement equipment
• Industrial process control instrumentation
• Medical imaging signal processing

Procurement Notes

Verify the specific suffix designation when ordering, as the provided reference indicates 'AD664TD-BIP/883B' which may denote military or aerospace qualification standards distinct from the commercial 'AD664BD-BIP'. Confirm availability status directly with authorized distributors, as stock levels for this component type can be limited. Ensure the required packaging format matches the procurement specification, noting that tube packaging is standard for this package style.

Selection Notes

Select this component when a system requires four synchronized 12-bit DAC channels in a single package. Verify that the application can accommodate the ±11.4 V to ±16.5 V analog supply range and 5 V digital logic levels. Consider the 28-CDIP package dimensions for PCB layout constraints. Compare performance metrics such as settling time and linearity against alternative quad DACs if higher speed or different interface protocols are required.

Part Context

This part belongs to the AD664 family of quad DACs from Analog Devices. Variants within the series, such as the AD664BD-BIP, share similar core functionalities but may differ in temperature ranges, accuracy grades, or qualification standards. The 'TD' suffix typically indicates a specific temperature or reliability grade compared to other letters in the product code.

Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided source material. Engineering teams should consult official Analog Devices documentation for cross-reference recommendations based on specific electrical and mechanical requirements.
