DAC101C081QISDX/NOPB

Digital To Analog Converters Overview

The DAC101C081QISDX/NOPB is a single-channel, 10-bit digital-to-analog converter (DAC) from Texas Instruments. It operates on a supply voltage range of 2.7 V to 5.5 V and utilizes the supply voltage as its internal reference. The device features an I2C-compatible 2-wire interface supporting Standard (100 kHz), Fast (400 kHz), and High-Speed (3.4 MHz) modes. Key electrical specifications include a maximum settling time of 6 µs, a typical power consumption of 380 µW at 3 V, and rail-to-rail buffered voltage output. It is AEC Q100 Grade 1 qualified for automotive applications and housed in a compact 6-lead WSON package.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's latest documentation to confirm package type and tape-and-reel specifications. Ensure the component meets RoHS compliance requirements for your assembly process. Cross-reference the datasheet revision history to validate that all electrical parameters match your design constraints before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a single-channel, low-power DAC with automotive reliability is required. The use of the supply voltage as the reference simplifies external circuitry compared to devices requiring separate reference inputs. Verify that the I2C bus capacitance limits are respected for the chosen communication speed mode to ensure signal integrity across the SCL and SDA lines.

Digital To Analog Converters Part Context

This part belongs to the DAC101C081 family, which includes pin-compatible variants such as the standard DAC101C081 and the DAC101C085. The DAC101C085 differs by utilizing an external reference voltage and offering additional address options via an extra pin. Other resolutions within the same architecture include the 8-bit DAC081C081 and the 12-bit DAC121C081.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible alternatives include the non-automotive DAC101C081ISDX/NOPB and the externally referenced DAC101C085 series. When substituting, verify that the replacement part supports the required I2C clock speeds and that the reference configuration matches the existing board design.
