DAC43508RTER

Digital To Analog Converters Overview

The DAC43508RTER is an octal, 8-bit buffered voltage-output digital-to-analog converter (DAC) from Texas Instruments. It operates on a single supply voltage ranging from 1.8 V to 5.5 V and supports an external reference input of the same range. The device features a 3-wire serial peripheral interface (SPI) for data communication and includes a load DAC (LDAC) pin for simultaneous output updates. It provides per-channel power-down registers and achieves ±1 LSB differential nonlinearity (DNL). The component is housed in a 16-pin WQFN package measuring 3 mm × 3 mm.

Digital To Analog Converters Feature Summary

• Octal channel architecture with individual user-programmable power-down control
• Low-power design optimized for battery-operated systems
• Compact 3 mm × 3 mm WQFN footprint

Digital To Analog Converters Applications

• Multifunction printers
• Display panels for TVs
• OLED TV modules
• Virtual reality headsets
• Currency counters
• Automatic teller machines (ATM)

Digital To Analog Converters Procurement Notes

Verify that the ordering suffix 'RTER' corresponds to the tape-and-reel packaging format specified in the manufacturer's documentation. Confirm that the specific revision level matches the required production standards. Ensure compatibility with the intended PCB layout regarding the exposed thermal pad connection to AGND.

Digital To Analog Converters Selection Notes

Select this component when eight independent analog outputs are required within a constrained board area. The wide supply voltage range allows flexibility in system power design. Verify that the 8-bit resolution meets the application requirements, as higher precision variants like the DAC53508 or DAC63508 are available in the same package.

Digital To Analog Converters Part Context

The DAC43508 belongs to the DACx3508 family, which also includes the 10-bit DAC53508 and the 12-bit DAC63508. These devices share identical pinouts and physical dimensions, facilitating easy upgrades in density without redesigning the printed circuit board. They are designed for high-density, low-power applications requiring multiple analog channels.

Digital To Analog Converters Replacement Considerations

The DAC53508RTER and DAC63508RTER are direct pin-compatible replacements offering higher resolution. For lower resolution needs, verify availability of older legacy parts, though the DACx3508 series is currently the primary production focus.
