DAC7565IAPWR

Digital To Analog Converters Overview

The DAC7565IAPWR is a quad-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features ultra-low glitch energy and voltage-buffered outputs within a TSSOP-16 package. The device operates on a single analog and digital power supply ranging from 2.7 V to 5.5 V. It supports serial interfaces including SPI, Microwire, QSPI, and DSP modes with data rates up to 200 kS/s per channel. Key performance metrics include a settling time of 10 µs, differential nonlinearity of ±0.1 LSB, integral nonlinearity of ±0.5 LSB, and a signal-to-noise ratio of 81 dB. Power consumption is specified at 2.9 mW.

Digital To Analog Converters Feature Summary

• Quad-channel architecture providing four independent 12-bit DACs in a compact surface-mount package.
• Ultra-low glitch energy design ensures clean transitions during code changes, minimizing output spikes.
• Integrated voltage buffers deliver high drive capability for direct connection to downstream circuits.
• Flexible serial interface compatibility allows integration with standard microcontroller and DSP systems.

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Portable instrumentation utilizing low-power, single-supply operation
• Programmable gain amplifiers and variable reference sources
• Battery-powered test equipment needing precise analog output control

Digital To Analog Converters Procurement Notes

Verify the suffix 'R' indicates tape-and-reel packaging distinct from the tube-packaged 'PW' variant. Confirm RoHS compliance status through official manufacturer documentation prior to procurement. Ensure ESD handling protocols are followed due to moisture sensitivity classification. Validate that the specific revision matches the required datasheet specifications for your application design.

Digital To Analog Converters Selection Notes

Select this component when four independent 12-bit channels are required in a single package. Compare against the DAC7564 if only two channels are needed or the DAC8565 for higher 16-bit resolution. Consider the 200 kS/s update rate and 10 µs settling time for bandwidth requirements. Verify interface compatibility with the host controller's available serial ports.

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 DAC7564 and DAC7568 but differs in channel count and pinout configuration. The IAPWR designation specifies industrial temperature range operation (-40°C to +105°C) and tape-and-reel packaging for automated assembly processes.

Digital To Analog Converters Replacement Considerations

DAC7564IAPWR offers identical electrical specifications but provides only two channels instead of four. DAC7568IAPWR provides eight channels while maintaining similar performance characteristics. Direct pin-for-pin substitution requires verifying channel count requirements and software initialization sequences compatible with the specific device variant.
