DAC101C085CIMMX

Digital To Analog Converters Overview

The DAC101C085CIMMX is a single-channel, 10-bit digital-to-analog converter manufactured by Texas Instruments. It operates within an extended supply voltage range of 2.7 V to 5.5 V and utilizes an external reference voltage (VREF). 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 integral non-linearity (INL) of ±2 LSB, a maximum differential non-linearity (DNL) of +0.3/-0.2 LSB, and a typical settling time of 6 µs. Power consumption is typically 380 µW at 3 V and 730 µW at 5 V in normal operation.

Digital To Analog Converters Procurement Notes

Verify the specific ordering suffix against the manufacturer's official documentation to confirm package type and temperature rating. Confirm RoHS compliance status through the datasheet or product folder. Ensure the component source provides valid traceability for quality assurance purposes.

Digital To Analog Converters Selection Notes

Select this component when a low-power, single-channel DAC with an external reference is required. Verify that the system bus supports the desired I2C speed mode. Check that the load capacitance does not exceed the specified maximum limit of 1500 pF for stable operation.

Digital To Analog Converters Part Context

This part belongs to the DAC101C08x family, which includes pin-compatible variants such as the DAC101C081 and DAC121C085. The DAC101C085 specifically distinguishes itself from the DAC101C081 by providing an external reference pin (VREF) instead of using the supply voltage as the reference.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives include the DAC101C081CIMMX/NOPB and DAC121C085CIMMX/NOPB. Verify functional compatibility regarding reference voltage configuration before substitution.

Digital To Analog Converters FAQ

How does the DAC101C085 differ from the DAC101C081?

The DAC101C085 uses an external reference voltage applied to the VREF pin, whereas the DAC101C081 uses the supply voltage (VA) as its reference.

What is the maximum operating frequency for the I2C interface?

The device supports Standard mode (100 kHz), Fast mode (400 kHz), and High-Speed mode (up to 3.4 MHz).

Is the DAC101C085 guaranteed to be monotonic?

Yes, the device ensures monotonicity up to 10 bits.
