Overview
The AD667JNZ is a 12-bit voltage-output digital-to-analog converter (DAC) manufactured by Analog Devices Inc. It features an internal reference and dual-buffered input latches, eliminating the need for external components in many applications. The device utilizes a parallel interface and operates with analog supply voltages ranging from 11.4 V to 16.5 V and a 5 V digital supply. Key performance metrics include a settling time of 4 µs to 0.01%, differential nonlinearity (DNL) of ±0.5 LSB, and integral nonlinearity (INL) of ±0.5 LSB. It is housed in a 28-pin plastic DIP package and supports through-hole mounting.
Feature Summary
- 12-bit resolution with R-2R architecture
- Internal high-stability Zener reference voltage source
- Dual-buffered input latch structure for microprocessor compatibility
- Settling time of 4 µs to 0.01% accuracy
Applications
- Microprocessor interfaces requiring direct bus connection
- Industrial control systems
- Aerospace instrumentation
Procurement Notes
Verify component authenticity through authorized distributors or official manufacturer channels. Confirm RoHS compliance status as historical data may vary. Check for obsolescence notices, as some variants in the AD667 family have been discontinued. Ensure packaging integrity upon receipt to prevent damage to the ceramic or plastic DIP leads.
Selection Notes
Select the AD667JNZ when a 12-bit monolithic DAC with internal reference and dual buffering is required. Compare DNL/INL specifications against application tolerance; this grade offers ±0.5 LSB linearity. Consider the 28-PDIP package constraints for PCB layout. Verify that the 4 µs settling time meets system speed requirements compared to faster alternatives if present.
Part Context
The AD667 series comprises complete 12-bit DACs designed for high-speed, high-accuracy applications. The J suffix typically denotes a specific performance grade within the family, often covering commercial temperature ranges. This part integrates laser-trimmed thin-film resistors and bipolar current-switching switches to ensure monotonicity over the operating temperature range.
Replacement Considerations
- AD667JN: Non-RoHS compliant version of the same package and specification.
FAQ
What is the output type of the AD667JNZ?
The AD667JNZ provides a buffered voltage output.
Does the AD667JNZ require an external reference?
No, it includes an internal high-stability embedded Zener reference voltage source.
What is the maximum power dissipation?
Typical power dissipation is approximately 300 mW to 555 mW depending on specific operating conditions and grade variations, though the datasheet specifies typical values around 300 mW including the reference.
