ADC082S021CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC082S021CIMMX/NOPB is a dual-channel, 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It operates with a sampling rate ranging from 500 kSPS to 1 MSPS and accepts single-ended input signals. The device utilizes a standard SPI-compatible serial interface for data communication. It functions within an analog and digital supply voltage range of 2.7 V to 5.25 V. Key performance metrics include a signal-to-noise ratio (SNR) of 49.6 dB, a differential nonlinearity (DNL) of 0.4 LSB, and an integral nonlinearity (INL) of 0.4 LSB. The component is housed in an 8-pin VSSOP package and supports an operating temperature range from -40°C to +85°C.

Analog To Digital Converters (ADC) Selection Notes

Select this component when dual-channel resolution is required alongside minimal power usage. The 8-bit resolution suits applications where high precision is not critical but cost and speed are priorities. Verify that the system clock frequency aligns with the desired sampling rate to maintain specified linearity and noise performance levels during operation.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC082S021 family of dual-channel converters. It shares architectural similarities with other members like the ADC082S101 but differs in channel count and specific timing parameters. The family targets general-purpose data acquisition tasks where space constraints limit the use of larger packages or multi-chip solutions.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the ADC082S021CIMM/NOPB which shares identical electrical specifications but may differ in reel packaging configuration. Other compatible alternatives within the same series should be evaluated based on pin compatibility and software register alignment to ensure seamless integration without hardware redesign.
