The AD664JN-UNI is a monolithic integrated circuit containing four independent 12-bit voltage-output digital-to-analog converters (DACs). Manufactured by Analog Devices Inc., this component utilizes a double-buffered input latch structure and supports data readback operations. All read and write functions are managed through a single microprocessor-compatible I/O port, simplifying system integration. The device operates with parallel digital inputs to generate precise analog voltage outputs across its four channels.
The AD664 series represents a family of high-performance quad DACs from Analog Devices. The AD664JN-UNI variant specifically denotes the commercial grade version in a DIP package. This part belongs to the broader AD664 product line, which includes various packaging options and military-grade compliant versions such as the AD664SD-BIP/883B.
For surface mount requirements, the AD664JPZ or AD664KPZ in PLCC-44 packages offer equivalent electrical performance. For through-hole applications requiring higher reliability standards, the AD664SD-BIP/883B provides MIL-STD-883 compliance. Verify pin compatibility and thermal specifications when transitioning between package types.
