DAC7578SPW

Digital To Analog Converters Overview

The DAC7578SPW is an octal, 12-bit digital-to-analog converter manufactured by Texas Instruments. It features eight buffered voltage outputs and operates on a single supply ranging from 2.7 V to 5.5 V for both analog and digital domains. The device utilizes a 2-wire I2C-compatible serial interface for data input. Key performance metrics include a sampling rate of 55.55 kS/s, a settling time of 12 µs, and a typical power consumption of 3.4 mW. It is housed in a 16-pin TSSOP package and supports an operating temperature range from -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates eight independent 12-bit DAC channels with internal output buffers within a compact surface-mount package.
• Supports standard two-wire I2C serial communication interface for simplified system connectivity.
• Includes a reset function that forces all DAC outputs to mid-scale upon power-up or hardware reset assertion.

Digital To Analog Converters Applications

• Multi-channel process control systems requiring isolated analog signal generation
• Portable instrumentation utilizing low-power, multi-output voltage references
• Industrial automation controllers needing multiple calibrated analog outputs

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's current datasheet to confirm package type and tape-and-reel specifications. Ensure compatibility with I2C bus voltage levels and check for any recent design changes or lifecycle status updates before finalizing procurement plans.

Digital To Analog Converters Selection Notes

Select this component when eight independent 12-bit voltage outputs are required in a space-constrained design. It is suitable for applications demanding low power consumption and wide industrial temperature operation. Compare DNL and INL specifications against system accuracy requirements to ensure compliance with signal integrity needs.

Digital To Analog Converters Part Context

This part belongs to the DAC7578 family of octal DACs. It shares architectural similarities with the DAC6578 (10-bit) and DAC5578 (8-bit) variants, offering different resolution options within the same pinout and interface framework. This allows for design flexibility while maintaining consistent board layout strategies across product lines.

Digital To Analog Converters Replacement Considerations

The DAC7578SPWR serves as the reel-based equivalent for automated assembly. For lower resolution needs, the DAC6578SPW (10-bit) and DAC5578SPW (8-bit) are pin-compatible alternatives. Verify that the substitute meets the specific linearity and power requirements of the application.
