DAC101C081CISDX/NOPB

Digital To Analog Converters Overview

The DAC101C081CISDX/NOPB is a 10-bit, single-channel voltage-output digital-to-analog converter 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 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 in normal operation.

Digital To Analog Converters Feature Summary

• Rail-to-rail voltage output amplifier capable of driving loads up to 1500 pF.
• I2C-compatible serial interface with support for high-speed mode up to 3.4 MHz.
• Power-on reset circuit ensures the DAC output initializes to zero volts upon startup.
• Configurable power-down modes reduce current consumption to less than 1 µA.

Digital To Analog Converters Applications

• Industrial process control systems
• Portable battery-operated instruments
• Digital gain and offset adjustment circuits
• Programmable voltage and current sources

Digital To Analog Converters Procurement Notes

Verify the specific suffix 'CISDX' corresponds to the WSON-6 package and tape-and-reel delivery format. Confirm that the 'NOPB' designation indicates lead-free and RoHS compliance. Ensure the ordering quantity aligns with the manufacturer's standard reel size requirements for this component.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution is required alongside minimal board space constraints due to the small WSON-6 footprint. It is suitable for designs needing rail-to-rail output swing without external buffering. Consider the DAC101C085 if an external reference voltage pin is necessary instead of using the supply voltage as the reference.

Digital To Analog Converters Part Context

This device belongs to the DAC101C08xx family of micro-power digital-to-analog converters. It shares pin compatibility with the 8-bit DAC081C081 and the 12-bit DAC121C081 variants. The family allows designers to scale resolution while maintaining consistent interface protocols and physical dimensions across different product generations.

Digital To Analog Converters Replacement Considerations

Pin-compatible alternatives within the same family include the DAC081C081 for 8-bit applications and the DAC121C081 for 12-bit applications. For external reference requirements, the DAC101C085 serves as a functional equivalent with an additional VREF pin and an 8-lead VSSOP package option.

Digital To Analog Converters FAQ

How is the slave address configured on the DAC101C081?

The 7-bit slave address is configured via the ADR0 pin, which sets the two least significant bits (A1 and A0). This allows for three distinct address options per I2C bus.

What is the maximum load capacitance the DAC101C081 can drive?

The device can drive a maximum load capacitance of 1500 pF to ground or VA, provided the resistive load is infinite or 2 kΩ.

Does the DAC101C081 use an external reference voltage?

No, the DAC101C081 uses the supply voltage (VA) as its internal reference. An external reference is only available on the pin-compatible DAC101C085 variant.
