DAC61408RHAR

Digital To Analog Converters Overview

The DAC61408RHAR is an 8-channel, 14-bit digital-to-analog converter manufactured by Texas Instruments. It features a high-voltage output capability and includes an internal reference. The device operates on a single analog and digital power supply ranging from 4.5V to 5.5V. It utilizes a 4-wire SPI serial interface for data communication. Key performance metrics include a settling time of 12 microseconds and a differential nonlinearity (DNL) of 1 LSB. The component is housed in a 40-pin VQFN package with dimensions of 6x6 mm. It supports surface mount installation and functions within a temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Integrates eight independent 14-bit DAC channels with high-voltage output stages
• Includes an internal voltage reference to simplify system design
• Supports standard 4-wire serial peripheral interface (SPI) communication
• Operates reliably across extended industrial temperature ranges

Digital To Analog Converters Applications

• Industrial process control systems requiring multi-channel signal generation
• Programmable logic controller (PLC) analog output modules
• Test and measurement equipment needing precise voltage references
• Automotive sensor simulation and actuator control circuits

Digital To Analog Converters Procurement Notes

Verify the specific suffix RHAR corresponds to the reel packaging configuration when ordering. Confirm that the 14-bit resolution variant matches the application requirements, as the DAC61408 family may offer other bit-depth options. Ensure the 40-VQFN footprint aligns with the PCB layout specifications. Check for RoHS compliance status if environmental regulations apply to the final assembly.

Digital To Analog Converters Selection Notes

Select this component when eight synchronized analog outputs are required from a single IC. The internal reference eliminates the need for external precision voltage sources, reducing board space. The high-voltage output simplifies interfacing with downstream components without additional amplification stages. Verify that the 12us settling time meets the system's update rate requirements.

Digital To Analog Converters Part Context

This part belongs to the DACx1408 family from Texas Instruments, which provides multi-channel solutions for industrial applications. The DAC61408 specifically denotes the 14-bit resolution variant within this series. Other members like the DAC71408 or DAC81408 share similar architectures but differ in resolution or channel count. This family is designed for cost-effective, high-performance analog output generation.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes within the same family include the DAC71408RHAR and DAC81408RHAR, though these offer different resolutions. Cross-family replacements require careful evaluation of pinout compatibility and electrical characteristics. Always verify that the alternative device supports the required 4-wire SPI interface and operating voltage range.
