DAC53508RTER

Digital To Analog Converters Overview

The DAC53508RTER is an octal, 10-bit digital-to-analog converter (DAC) from Texas Instruments. It features buffered voltage outputs and communicates via a 3-wire SPI interface. The device operates on a single power supply ranging from 1.8 V to 5.5 V, with an external reference input supporting the same range. Key electrical specifications include ±1 LSB differential nonlinearity (DNL), ±1 LSB integral nonlinearity (INL), and a typical settling time of 10 µs. It consumes 0.1 mA per channel at 1.8 V and includes user-programmable power-down registers. The component is housed in a compact 16-pin WQFN package measuring 3 mm × 3 mm.

Digital To Analog Converters Feature Summary

• Octal architecture providing eight independent buffered voltage output channels within a single integrated circuit.
• Low-power design featuring programmable per-channel power-down modes that reduce current consumption significantly when inactive.
• Compact physical footprint utilizing a tiny 3 mm × 3 mm 16-pin WQFN package suitable for high-density board layouts.

Digital To Analog Converters Applications

• Multifunction printers
• Display panels for televisions
• OLED television systems
• Virtual reality headsets
• Currency counters

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix 'RTER' corresponds to the tape-and-reel packaging format required for automated assembly processes. Confirm that the external reference voltage requirements align with the system's available power rails, as the device relies on an external reference rather than an internal one. Ensure the PCB layout accommodates the thermal pad connection to AGND for optimal heat dissipation.

Digital To Analog Converters Selection Notes

Select this component when an application requires multiple analog voltage outputs controlled by a microcontroller via a serial interface. It is appropriate for battery-operated systems due to its low quiescent current and wide operating voltage range. Consider alternative resolutions like the DAC43508 or DAC63508 if higher precision or lower cost is prioritized over the 10-bit specification.

Digital To Analog Converters Part Context

This part belongs to the DACx3508 family, which also includes the 8-bit DAC43508 and the 12-bit DAC63508. All members share identical pinouts and functional block diagrams, allowing for direct pin-compatible upgrades or downgrades depending on resolution needs. The family is designed for low-power, space-constrained applications requiring multiple simultaneous analog outputs.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible substitutes within the same family include the DAC43508RTER for 8-bit resolution and the DAC63508RTER for 12-bit resolution. Verify that the specific performance metrics of the replacement meet the original design requirements regarding linearity and speed.
