DAC63508RTER

Digital To Analog Converters Overview

The DAC63508RTER is an octal, 12-bit, buffered voltage-output digital-to-analog converter manufactured by Texas Instruments. It operates within a supply voltage range of 1.8 V to 5.5 V and supports a wide operating temperature from -40°C to +125°C. The device features a 3-wire SPI interface with a maximum clock frequency of 50 MHz at higher voltages. Key electrical specifications include ±1 LSB differential nonlinearity (DNL), a settling time of 10 µs, and a quiescent current of 0.1 mA per channel. It utilizes a 16-pin WQFN package measuring 3 mm × 3 mm.

Digital To Analog Converters Feature Summary

• Per-channel user-programmable power-down registers allow individual output buffers to enter a low-power state connected to AGND via 10kΩ resistors.
• Integrated LDAC pin enables synchronous or simultaneous updates across all eight channels for coordinated system timing.
• Low-power start-up mode ensures outputs are powered down upon initialization, reducing inrush current and system noise.

Digital To Analog Converters Applications

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

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 component meets RoHS3 compliance standards as specified in the manufacturer's documentation before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when high-density integration is required due to its compact 3mm x 3mm footprint. Ensure the application benefits from the low quiescent current consumption per channel, particularly for battery-operated systems requiring extended operational life without frequent recharging.

Digital To Analog Converters Part Context

This part belongs to the DACx3508 family, which includes the 8-bit DAC43508 and 10-bit DAC53508 variants. All members share identical pinouts and functional block diagrams, differing only in resolution. This allows for design flexibility and potential future-proofing within the same hardware layout constraints.

Digital To Analog Converters Replacement Considerations

Direct substitutes within the same family include the DAC43508RTER and DAC53508RTER. These parts maintain pin compatibility and identical physical dimensions while offering lower resolution options if the 12-bit precision is not strictly necessary for the target application.

Digital To Analog Converters FAQ

Does the DAC63508 support readback operations?

No, the device communicates through a write-only 3-wire serial peripheral interface (SPI) and does not support reading back internal register states or DAC values.

How is the reference voltage configured?

The device requires an external reference input on the VREFIN pin. To use the supply voltage as the reference, connect VREFIN directly to VDD.

What is the behavior of the outputs during power-on?

The outputs can be configured to start in a powered-down state connected to AGND via 10kΩ resistors, preventing undefined analog levels until a power-up command is issued.
