DAC7565IAPW

Digital To Analog Converters Overview

The DAC7565IAPW is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features a resistor-string architecture with buffered voltage outputs and supports multiple serial interfaces including SPI, Microwire, QSPI, and DSP modes. The device operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. Key performance metrics include a settling time of 12 µs, a signal-to-noise ratio of 81 dB, and low power consumption of 2.9 mW. Nonlinearity specifications are ±0.5 LSB for INL and ±0.1 LSB for DNL. It is housed in a 16-pin TSSOP package and functions within an industrial temperature range of -40°C to +105°C.

Digital To Analog Converters Procurement Notes

Verify the specific suffix against official datasheets to confirm package type and tape-and-reel versus tube packaging options. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the ordering part number matches the exact pinout and electrical characteristics defined in the manufacturer's documentation before procurement.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit channels are required in a compact surface-mount footprint. Compare settling time and nonlinearity specs against application tolerance requirements. Verify that the serial interface timing aligns with the host microcontroller capabilities. Consider the operating temperature range if the environment exceeds standard commercial limits.

Digital To Analog Converters Part Context

This part belongs to the DAC7565 family of precision digital-to-analog converters. It shares architectural similarities with the DAC8565 but offers lower resolution. The IAPW designation indicates an industrial temperature grade variant in a TSSOP-16 package. It serves as a cost-effective solution for applications needing moderate accuracy with low power consumption.

Digital To Analog Converters Replacement Considerations

The DAC7564IAPW is a documented substitute offering identical pinout and functionality with potentially different nonlinearity specifications. Verify register compatibility and electrical parameter tolerances before substitution.
