DAC121S101CIMM/NOPB

Digital To Analog Converters Overview

The DAC121S101CIMM/NOPB is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates on a single supply voltage ranging from 2.7 V to 5.5 V for both analog and digital domains. The device features a serial interface compatible with standard protocols including SPI, QSPI, Microwire, and DSP modes. Key electrical specifications include a sampling rate of 1.8 MS/s, a settling time of 8 µs, and a typical power consumption of 640 µW. Nonlinearity performance is characterized by a differential nonlinearity (DNL) of 1 LSB and an integral nonlinearity (INL) of ±2.6 LSB. The output stage provides a buffered voltage signal with rail-to-rail swing capability.

Digital To Analog Converters Feature Summary

• Integrated rail-to-rail output buffer enables full-scale voltage swing across the entire supply range without external components.
• Flexible serial communication interface supports multiple standard protocols for simplified system integration.
• Optimized low-power architecture delivers micro-watt level consumption suitable for battery-operated applications.

Digital To Analog Converters Procurement Notes

Verify the complete part number including the NOPB suffix to ensure lead-free compliance and specific package variant accuracy. Confirm that the required operating temperature range aligns with the commercial grade specifications defined in the official datasheet. Cross-reference the manufacturer's current lifecycle status to ensure long-term availability for production designs.

Digital To Analog Converters Selection Notes

Select this component when a single-channel 12-bit resolution is sufficient for the application requirements. Ensure the system clock speed supports the maximum 1.8 MS/s sampling rate without exceeding timing constraints. Verify that the host microcontroller supports the selected serial interface mode, such as SPI or Microwire, for proper data transmission.

Digital To Analog Converters Part Context

This device belongs to the DAC121S101 family of micro-power digital-to-analog converters. It shares architectural similarities with the DAC081S101 and DAC101S101, differing primarily in resolution and precision metrics.
