DAC101C085CIMMX/NOPB

Digital To Analog Converters Overview

The DAC101C085CIMMX/NOPB is a single-channel, 10-bit digital-to-analog converter manufactured by Texas Instruments. It operates within an extended supply voltage range of 2.7 V to 5.5 V and utilizes an external reference voltage (VREF). The device features a rail-to-rail buffered analog output and supports I2C-compatible serial communication in Standard (100 kHz), Fast (400 kHz), and High-Speed (3.4 MHz) modes. Key electrical specifications include a maximum full-scale error of -0.7% FSR, a settling time of 6 µs, and typical power consumption of 380 µW at 3 V. It is housed in an 8-lead VSSOP package and functions across an industrial temperature range of -40°C to +125°C.

Digital To Analog Converters Feature Summary

• Supports nine distinct I2C addressing options via pin-selectable ADR0 and ADR1 inputs for multi-device bus configurations.
• Integrates a power-on reset circuit that ensures the analog output initializes to zero volts upon startup.
• Includes programmable power-down control logic to minimize energy usage during idle 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 the specific ordering suffix against manufacturer documentation to confirm package type and temperature grade. Ensure the external reference voltage source meets the required noise and impedance specifications for optimal linearity. Confirm that the target application environment remains within the specified operating temperature limits.

Digital To Analog Converters Selection Notes

Select this component when a low-pin-count solution with an external reference is required. Compare against the DAC101C081 if the system design allows using the supply voltage as the reference instead. Evaluate the available I2C address space to ensure compatibility with existing bus devices.

Digital To Analog Converters Part Context

This part belongs to the DAC101C08x family of micro-power digital-to-analog converters. It shares functional compatibility with the DAC101C081 but differs in its requirement for an external reference voltage and its availability in an 8-lead VSSOP package. The family also includes variants with different resolutions such as the DAC081C085 and DAC121C085.

Digital To Analog Converters Replacement Considerations

The DAC101C085CIMM is a direct pin-compatible alternative. Verify that any substitute maintains the same 8-lead VSSOP footprint and I2C interface timing requirements.
