DAC081S101CIMMX/NOPB

Digital To Analog Converters Overview

The DAC081S101CIMMX/NOPB is an 8-bit micro power digital-to-analog converter manufactured by Texas Instruments. It features a single channel with a sampling rate of 1.8 MS/s and a settling time of 3 µs. The device operates on a voltage buffered output type, supporting analog and digital supply voltages ranging from 2.7 V to 5.5 V. It utilizes a 3-Wire, DSP, Microwire, QSPI, or SPI interface. Key performance metrics include a differential nonlinearity (DNL) of +/- 0.1 LSB, integral nonlinearity (INL) of +/- 0.75 LSB, and a gain error of 1% FSR. Power consumption is rated at 630 µW, and it functions within a temperature range of -40°C to +105°C in a VSSOP-8 package.

Digital To Analog Converters Procurement Notes

Verify the manufacturer designation as Texas Instruments, which acquired National Semiconductor's semiconductor business. Confirm the specific suffix NOPB indicates lead-free and RoHS compliance. Ensure the VSSOP-8 package variant matches the required PCB footprint. Validate the extended industrial temperature rating against environmental specifications.

Digital To Analog Converters Selection Notes

Select this component when an 8-bit resolution is sufficient for the application requirements. Consider the 1.8 MS/s sampling rate for moderate-speed signal generation needs. Evaluate the low power consumption profile for energy-constrained designs. Compare against higher-resolution siblings like the DAC101S101 or DAC121S101 if greater precision is necessary.

Digital To Analog Converters Part Context

This device belongs to the DAC081S101 family, which includes pin-compatible 10-bit and 12-bit variants. Originally developed by National Semiconductor before its acquisition by Texas Instruments, the series provides scalable resolution options. The family shares identical interfaces and packaging, facilitating easy upgrades from 8-bit to 12-bit performance without redesigning the board layout.

Digital To Analog Converters Replacement Considerations

The DAC101S101 and DAC121S101 are direct pin-compatible replacements offering higher resolution. For legacy sourcing, verify availability of original National Semiconductor branded units if strictly required.
