DAC101C081CISD/NOPB

Digital To Analog Converters Overview

The DAC101C081CISD/NOPB is a single-channel, 10-bit 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 2-wire serial 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. The component is housed in a compact 6-lead WSON package measuring 2.20 mm × 2.50 mm.

Digital To Analog Converters Feature Summary

• Pin-selectable address options allowing multiple devices on a single bus.
• Power-on reset circuit ensures zero-volt startup condition.

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 'CISD' corresponds to the WSON-6 package variant when sourcing. Confirm RoHS compliance status via the manufacturer's latest documentation. Ensure the ordering quantity matches the standard reel packaging requirements specified by the distributor. Cross-reference the datasheet revision history for any updates to electrical characteristics or pin configurations prior to final procurement.

Digital To Analog Converters Selection Notes

Select this component for applications requiring low power consumption and minimal board space. The use of the supply voltage as the reference simplifies design but requires careful decoupling of the VA pin. Consider the DAC101C085 if an external reference voltage is preferred over the supply rail. Verify that the I2C bus speed requirements align with the device's support for Standard, Fast, and High-Speed modes.

Digital To Analog Converters Part Context

This device belongs to the DAC101C08x family of micro-power DACs. It shares pin compatibility with the 8-bit DAC081C081 and the 12-bit DAC121C081 variants. The 'Q' suffix denotes automotive-grade qualification (AEC Q100 Grade 1). The 'NOPB' suffix indicates lead-free packaging without blue molding compound. The 'C' in the part number specifies the industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Replacement Considerations

Direct pin-compatible alternatives within the same family include the DAC081C081 (8-bit resolution) and the DAC121C081 (12-bit resolution). For designs requiring an external reference instead of the supply rail, the DAC101C085 serves as a functional equivalent with an 8-lead VSSOP package.
