DAC7568IAPW

Digital To Analog Converters Overview

The DAC7568IAPW is an eight-channel, 12-bit voltage-output digital-to-analog converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from +2.7V to +5.5V and features a built-in 2.5V precision reference with 2ppm/°C drift. The device utilizes a high-speed 3-wire serial interface compatible with standard SPI, QSPI, Microwire, and DSP standards, supporting clock frequencies up to 50MHz. Key electrical specifications include a glitch energy of 0.1nV-s and rail-to-rail output buffers capable of sourcing or sinking current. It ensures monotonicity across the entire operating temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates an ultra-low glitch energy design to minimize code-dependent transient voltages during state changes.
• Features rail-to-rail on-chip output buffer amplifiers for direct drive capability without external components.
• Includes an internal 2.5V precision reference with low temperature drift, available in disabled or enabled states.
• Supports flexible multi-device daisy-chaining via a versatile 3-wire serial interface.

Digital To Analog Converters Applications

• Portable battery-powered instrumentation requiring low power consumption.
• Closed-loop servo control systems needing precise multi-channel analog outputs.
• Data acquisition systems utilizing synchronized channel updates.
• Programmable gain and attenuation adjustment circuits.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'IAPW' corresponds to the industrial temperature grade (-40°C to +125°C) and TSSOP-16 package configuration. Confirm RoHS compliance status and moisture sensitivity level requirements for your assembly process. Ensure the internal reference is configured correctly via the serial interface if a 5V full-scale output is required, as it defaults to disabled.

Digital To Analog Converters Selection Notes

Select this component when eight independent 12-bit channels are required within a compact footprint. Compare against the DAC8168 (14-bit) or DAC8568 (16-bit) if higher resolution is necessary, noting their functional compatibility. Consider the DAC7565 if only four channels are needed. Verify that the 50MHz serial clock speed meets your system's timing constraints and that the 2.7V to 5.5V supply range aligns with your power architecture.

Digital To Analog Converters Part Context

The DAC7568 belongs to a family of multi-channel DACs that includes the DAC8168 and DAC8568. These devices share identical pinouts and software compatibility, differing primarily in resolution (12-bit, 14-bit, and 16-bit respectively). This family is designed for applications requiring multiple synchronized analog outputs with high accuracy and low power consumption in small packages.

Digital To Analog Converters Replacement Considerations

The DAC7568IAPWG4 is a verified equivalent part number representing the same device with updated manufacturing guidelines. Direct functional substitutes within the same family include the DAC8168IAPW and DAC8568IAPW, provided higher resolution is acceptable. No other cross-manufacturer replacements are confirmed in the provided documentation.
