The AD664KN-BIP is a monolithic integrated circuit containing four complete 12-bit voltage-output digital-to-analog converters (DACs). It features double-buffered input latches and a data readback function, allowing all operations through a single microprocessor-compatible I/O port. The device utilizes an R-2R architecture with parallel interface connectivity. It operates within an analog supply range of ±11.4 V to ±16.5 V and a digital supply of 5 V. The component is housed in a surface-mount PLCC-44 package and supports an operating temperature range from -40°C to +85°C.
This component belongs to the AD664 series of quad DACs manufactured by Analog Devices. It is available in both DIP and surface-mount packages, with specific variants like the AD664TD-BIP/883B offering MIL-STD-883 compliance for ruggedized applications. The KN suffix typically denotes the surface-mount PLCC package variant.
The AD664BD-BIP is listed as a parameter-equivalent alternative. Verification of pinout compatibility and electrical specifications against the original datasheet is required before substitution.
