AD664 (23)

Four Complete Voltage Output DACs: The AD664 integrates four independent 12-bit digital-to-analog converters (DACs) on a single chip, enabling simultaneous multi-channel signal generation. This feature enhances system efficiency by reducing the need for multiple DAC components, saving space and power in multi-channel applications such as audio processing, instrumentation, and industrial control systems.
Data Register Readback Feature: The DACs include a readback function that allows the microprocessor to verify the data written to the DAC registers. This feature improves system reliability and debugging capabilities by ensuring accurate data transfer and reducing errors in critical applications like automated test equipment and precision control systems.
inchReset to Zero inch Override: The AD664 supports a
inchReset to Zero inch function, which can override the current DAC output and reset it to zero. This feature is particularly useful in safety-critical systems or during system initialization, ensuring predictable and safe operation in scenarios like emergency shutdowns or calibration routines.
Multiplying Operation: The DACs support multiplying operation, allowing them to function as digitally controlled attenuators when used with an external reference voltage. This flexibility expands the device's use cases to include applications like waveform generation, signal conditioning, and programmable gain control in communication systems.
Single Microprocessor-Compatible I/O Port: All four DACs share a single microprocessor-compatible I/O port for read and write operations, simplifying interface design and reducing the complexity of control logic. This feature enhances system integration and reduces development time, making the AD664 ideal for embedded systems and compact designs.
