DAC101S101CIMM

Digital To Analog Converters Overview

The DAC101S101CIMM is a 10-bit digital-to-analog converter manufactured by Texas Instruments, originally developed under the National Semiconductor brand. It utilizes a resistive string architecture and features a buffered voltage output. The device operates on a single supply voltage ranging from 2.7V to 5.5V for both analog and digital domains. It supports SPI and DSP data interfaces with a maximum clock rate of 30MHz. Key performance metrics include a settling time of 7.5µs, an integral nonlinearity (INL) of ±0.6 LSB, and differential nonlinearity (DNL) of +0.15/-0.05 LSB. It is housed in an 8-VSSOP package and functions within a temperature range of -40°C to 105°C.

Digital To Analog Converters Procurement Notes

Verify component authenticity through official manufacturer channels or authorized distributors. Confirm RoHS compliance status and check for specific suffix variations that may indicate different packaging or environmental certifications. Ensure the part number matches the exact revision required for your design specifications.

Digital To Analog Converters Selection Notes

Select this component when a 10-bit resolution and rail-to-rail output are required in a compact VSSOP package. Consider the DAC101S101QCMK/NOPB variant if automotive qualification (AEC-Q100) or extended temperature ratings up to 125°C are necessary. Verify interface compatibility with the host microcontroller's SPI or DSP mode.

Digital To Analog Converters Part Context

This device belongs to the DAC101S101 family, which includes pin-compatible 8-bit (DAC081S101) and 12-bit (DAC121S101) variants.
