ADC081S021CIMF

Analog To Digital Converters (ADC) Overview

The ADC081S021CIMF is a single-channel, 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with an analog and digital supply voltage range of 2.7V to 5.25V. The device supports sampling rates from 50 ksps to 200 ksps and features a single-ended input configuration. Data is transmitted via a standard SPI or DSP-compatible serial interface. It is housed in a surface-mount SOT-23-6 package and is rated for operation over an industrial temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a sample-and-hold amplifier with the ADC core for accurate signal capture.
• Supports flexible digital interfaces including standard SPI and DSP modes.
• Operates on a single low-voltage power supply for simplified system design.

Analog To Digital Converters (ADC) Applications

• Battery-powered portable instrumentation
• Industrial process control systems
• Consumer electronics with limited power budgets

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIMF' corresponds to the SOT-23-6 package and the -40°C to +85°C temperature grade. Confirm RoHS compliance status as per the latest manufacturer documentation. Ensure the ordering part number matches the required sampling rate specifications within the 50-200 ksps range before finalizing procurement.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and up to 200 ksps sampling speed are sufficient for the application. Compare against the ADC081S101 if higher 1 Msps throughput is required. Consider the ADC121S021 if greater 12-bit resolution is necessary, noting potential trade-offs in speed or cost. Verify that the single-ended input type aligns with the sensor output characteristics.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC081Sxx family of micro-power, single-channel SAR ADCs. It shares architectural similarities with the ADC101S021 and ADC121S021, differing primarily in resolution and maximum sampling rate. The CIMF designation indicates a specific commercial temperature grade and surface-mount packaging variant within the broader product line.

Analog To Digital Converters (ADC) Replacement Considerations

Direct functional substitutes include the ADC081S101 for higher speed applications or the ADC121S021 for higher resolution. Cross-reference pinouts and software compatibility when migrating between these variants within the same family.
