DAC101C081QISD/NOPB

Digital To Analog Converters Overview

The DAC101C081QISD/NOPB is a 10-bit, single-channel voltage-output 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 as its 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, integral non-linearity (INL) of ±2 LSB, and differential non-linearity (DNL) of +0.3/-0.2 LSB. Typical power consumption is 380 µW at 3 V and 730 µW at 5 V. The component is AEC-Q100 Grade 1 qualified and housed in a 6-lead WSON package measuring 2.20 mm × 2.50 mm.

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'Q' indicates AEC-Q100 Grade 1 qualification and automotive manufacturing flow. Confirm the 'ISD' suffix corresponds to the WSON-6 package variant. Ensure compatibility with the required I2C bus speed and address configuration via ADR0/ADR1 pins before finalizing orders.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution with rail-to-rail output is required in a small footprint. It is suitable for battery-operated equipment due to low power consumption. Consider the DAC101C085 if an external reference voltage is preferred over using the supply voltage as the reference.

Digital To Analog Converters Part Context

This part belongs to the DAC101C08xx family of micro-power digital-to-analog converters. It shares pin compatibility with the standard DAC101C081 and the external-reference DAC101C085. The family also includes 8-bit (DAC081C081) and 12-bit (DAC121C081) variants that maintain functional compatibility across different resolutions.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible alternatives within the same family include the DAC101C081 (non-automotive grade) and the DAC101C085 (external reference). For higher resolution requirements, the DAC121C081 or DAC121C085 are available.
