DAC101C081CISDX

Digital To Analog Converters Overview

The DAC101C081CISDX is a 10-bit, single-channel voltage-output digital-to-analog converter (DAC) manufactured by Texas Instruments. It operates from 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 serial 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 in normal operation. The component is housed in a compact 6-lead WSON package measuring 2.20 mm × 2.50 mm.

Digital To Analog Converters FAQ

How does the DAC101C081 handle the reference voltage?

The DAC101C081 uses the analog supply voltage (VA) as its internal reference. Consequently, the accuracy of the analog output depends directly on the stability and noise characteristics of the VA supply.

What is the maximum load capacitance supported by the output?

The output amplifier can drive a maximum load capacitance of 1500 pF to ground or to the supply voltage without requiring additional compensation.

Does the device support high-speed I2C communication?

Yes, the integrated I2C interface supports High-Speed mode, allowing clock frequencies up to 3.4 MHz, provided the bus capacitance limits are respected.
