DAC121S101CIMMX/NOPB

Digital To Analog Converters Overview

The DAC121S101CIMMX/NOPB is a single-channel, 12-bit digital-to-analog converter manufactured by Texas Instruments. It operates with an analog and digital supply voltage range of 2.7 V to 5.5 V. The device features a sampling rate of 1.8 MS/s and a settling time of 8 µs. It utilizes a buffered voltage output type and supports serial interfaces including SPI, Microwire, QSPI, and DSP modes. The component is housed in an 8-pin VSSOP package and functions within a temperature range of -40°C to +105°C. Key performance metrics include a differential nonlinearity (DNL) of ±0.1 LSB and an integral nonlinearity (INL) of ±0.75 LSB.

Digital To Analog Converters Feature Summary

• Micro power consumption design optimized for battery-operated applications
• Rail-to-rail output capability allowing full-scale signal swing
• Flexible serial interface compatibility with standard DSP protocols

Digital To Analog Converters Applications

• Portable instrumentation systems requiring low power consumption
• Battery-powered data acquisition modules
• Industrial process control loops with limited power budgets

Digital To Analog Converters Procurement Notes

Verify the specific suffix NOPB confirms lead-free compliance and RoHS status against current manufacturer documentation. Confirm the VSSOP-8 package variant matches the required footprint for PCB layout. Ensure the operating temperature grade aligns with the environmental conditions of the target application before finalizing procurement orders.

Digital To Analog Converters Selection Notes

Select this component when a balance between moderate resolution and high speed is required. The 1.8 MS/s update rate suits applications needing faster response than lower-speed DACs but does not demand ultra-high precision. Consider the serial interface requirements to ensure compatibility with the host microcontroller or DSP system architecture.

Digital To Analog Converters Part Context

This part 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. The CIMMX designation indicates the commercial temperature range and surface-mount packaging style used for general-purpose electronic assemblies.

Digital To Analog Converters Replacement Considerations

The DAC121S101CIMMX is functionally equivalent to the DAC121S101CIMMX/NOPB, with the latter specifying lead-free construction. Verify pinout compatibility if substituting with other members of the DAC121S101 series.
