AD667JPZ-REEL

Overview

The AD667JPZ-REEL is a 12-bit digital-to-analog converter (DAC) manufactured by Analog Devices Inc., housed in a 28-pin PLCC package. It integrates a high-stability embedded Zener reference voltage source and dual-buffered input latches, eliminating the need for external components. The device features a settling time of 3 µs to 0.01% accuracy and a maximum non-linearity error of ±1/2 LSB. It operates on dual power supplies ranging from ±12V to ±15V with a typical power consumption of 300 mW. The logic inputs are compatible with TTL and 5V CMOS standards, allowing direct interfacing with microprocessor buses.

Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm lot traceability and RoHS compliance status via official datasheets. Check current availability as specific variants may be discontinued or subject to limited supply constraints. Ensure storage conditions meet moisture sensitivity level requirements prior to soldering.

Selection Notes

Select this component for applications requiring precise 12-bit voltage conversion with integrated referencing. Verify that the ±12V to ±15V dual supply requirement aligns with system power architecture. Consider the 28-pin PLCC package dimensions for PCB layout. Evaluate thermal dissipation capabilities given the 300 mW power consumption at ambient operating temperatures.

Part Context

The AD667 series represents a family of complete voltage-output DACs designed for high-precision applications. The JPZ suffix indicates a plastic leaded chip carrier package variant within this lineage. This component belongs to Analog Devices' historical portfolio of monolithic converters featuring internal calibration and buffering capabilities.

Replacement Considerations
