DAC101C085CIMM/NOPB

Digital To Analog Converters Overview

The DAC101C085CIMM/NOPB is a single-channel, 10-bit 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 an external reference voltage input. The device features a 2-wire 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, a typical power consumption of 380 µW at 3 V, and rail-to-rail output swing. It is housed in an 8-lead VSSOP package.

Digital To Analog Converters Feature Summary

• Supports nine distinct I2C addressing options via pin-selectable address inputs for multi-device bus configurations.
• Features a power-on reset circuit that ensures the DAC output initializes to zero volts upon startup.
• Includes a dedicated power-down control mode to minimize current consumption during inactive periods.

Digital To Analog Converters Applications

• Industrial process control systems
• Portable battery-operated instruments
• Programmable voltage and current sources

Digital To Analog Converters Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific ordering suffix matches the required package and temperature grade. Ensure compliance with RoHS directives and check for any recent lifecycle status updates regarding availability.

Digital To Analog Converters Selection Notes

Select this model when an external reference voltage is required rather than using the supply voltage as the reference. Compare against the DAC101C081 if a supply-referenced design is acceptable, noting the difference in pinout and package type between the VSSOP-8 and smaller packages.

Digital To Analog Converters Part Context

This component belongs to the DAC101C08x family of micro-power DACs. It shares functional compatibility with the DAC101C081 but differs by providing an external reference pin and additional I2C address bits. It is part of a broader series including 8-bit and 12-bit variants designed for space-constrained applications.

Digital To Analog Converters Replacement Considerations

The DAC101C085CIMM/NOPB serves as a direct replacement for the discontinued DAC101C085CIMM. Both parts share identical pinouts and electrical characteristics, differing primarily in manufacturing compliance standards associated with the NOPB suffix.

Digital To Analog Converters FAQ

How does the DAC101C085 differ from the DAC101C081?

The DAC101C085 uses an external reference voltage (VREF) and offers nine I2C addressing options, whereas the DAC101C081 uses the supply voltage (VA) as the reference and supports only three address options.

What is the maximum serial clock frequency supported?

The device supports I2C Standard, Fast, and High-Speed modes, allowing for a maximum serial clock frequency of 3.4 MHz.
