Overview
The AD664BJ is a monolithic 12-bit quad digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It integrates four complete voltage-output DACs on a single chip, featuring double-buffered input latches and a data readback function. All operations are managed through a single microprocessor-compatible parallel I/O port. The device operates with analog supply voltages ranging from 11.4 V to 16.5 V and a digital supply of 5 V. Key performance metrics include a settling time of 10 µs, differential nonlinearity (DNL) of ±1 LSB, and integral nonlinearity (INL) of ±1 LSB. It supports surface mount installation and functions within a temperature range of -40°C to +85°C.
Feature Summary
- Four independent 12-bit voltage-output DACs on one monolithic IC
- Double-buffered input latch structure for simplified interfacing
- Data readback feature for verification of written values
- "Reset to Zero" override capability
Applications
- Automatic Test Equipment
- Robotics
- Process Control
- Disk Drives
- Instrumentation
Procurement Notes
Verify component authenticity and datasheet revision when sourcing the AD664BJ. Confirm that the specific suffix 'BJ' corresponds to the commercial grade specifications (±1 LSB linearity) rather than higher precision variants. Check for RoHS compliance status as historical industrial components may have varying environmental declarations depending on the manufacturing batch and current production status.
Selection Notes
Select the AD664BJ when a quad-channel 12-bit resolution is required with parallel interface compatibility. Ensure the application can accommodate the specified analog supply range of 11.4 V to 16.5 V. Compare DNL and INL specifications against other AD664 variants if tighter linearity is needed, as this model specifies ±1 LSB limits. Verify that the surface mount package type meets the PCB layout requirements.
Part Context
The AD664 belongs to the AD664 series of monolithic DACs, which also includes military-grade versions like the AD664TD-BIP/883B. These devices share the same core architecture but differ in packaging, temperature ranges, and precision specifications. The AD664BJ represents the commercial surface-mount variant, distinct from the through-hole DIP packages found in other family members.
Replacement Considerations
Publicly confirmed substitute part numbers for the AD664BJ are not available in the provided documentation. Engineering changes or pin-compatible alternatives should be verified directly with Analog Devices or authorized distributors.
