ADC081S021CIMFX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC081S021CIMFX/NOPB is a single-channel, 8-bit analog-to-digital converter manufactured by Texas Instruments. It utilizes Successive Approximation Register (SAR) architecture and operates with a sampling rate ranging from 50 ksps to 200 ksps. The device accepts single-ended inputs and communicates via a standard SPI or DSP-compatible interface. It functions within an analog and digital supply voltage range of 2.7V to 5.25V. The component is housed in a SC-70 (SOT-353) surface-mount package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CIMFX' against the manufacturer's official datasheet to confirm the exact tape-and-reel packaging quantity and marking details. Ensure the NOPB designation confirms lead-free and RoHS compliance status as per current environmental regulations before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a single-channel, 8-bit resolution is sufficient for the application. It is appropriate for designs requiring moderate speed up to 200 ksps with a wide supply voltage range. Consider alternative parts if differential input capability or higher resolution bits are required.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC081S family of low-cost, low-power analog-to-digital converters. It shares architectural similarities with other members like the ADC081S021 and ADC081S101, differing primarily in sampling speed and package options. The series is designed for cost-sensitive applications requiring reliable SPI communication.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements may include other variants within the ADC081S family such as the ADC081S021CIMF/NOPB, provided the sampling rate requirements align with the specific design constraints.
