ADC081C021CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC081C021CIMMX/NOPB is an 8-bit analog-to-digital converter from Texas Instruments, operating within a supply voltage range of 2.7 V to 5.5 V for both analog and digital domains. It features a single-ended input architecture with a sampling rate of 200 kS/s and supports SPI and DSP interfaces. The device is housed in an 8-pin VSSOP package, suitable for surface-mount installation. It functions across an extended temperature range from -40°C to +105°C, ensuring reliable performance in demanding environments while maintaining low power consumption characteristics typical of the series.

Analog To Digital Converters (ADC) Feature Summary

• Integrated sample-and-hold amplifier for accurate signal capture
• Compatible with standard serial communication protocols including SPI and DSP modes
• Designed for cost-sensitive applications requiring micro-power operation

Analog To Digital Converters (ADC) Applications

• Portable battery-powered instrumentation
• Industrial process control systems
• Consumer electronics with limited power budgets

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix NOPB indicates lead-free compliance and RoHS standards when sourcing. Confirm the CIMMX designation corresponds to the VSSOP-8 package variant required for your PCB layout. Ensure the supplier provides official datasheets matching the Texas Instruments part number to avoid counterfeit components. Check for any recent product change notices that might affect pinout or electrical specifications.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 200 kS/s speed are sufficient for the application. Consider the VSSOP-8 package size constraints against available board space. Evaluate the single-ended input requirement versus differential needs of other sensors. Compare power dissipation at the target operating voltage to ensure thermal limits are not exceeded in enclosed designs.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC081C021 family of high-speed, low-power ADCs. It shares architectural similarities with other members like the ADC081C027 but differs in resolution and interface options. The CIMMX/NOPB variant specifically denotes the commercial temperature grade and lead-free packaging. It serves as a bridge between high-resolution converters and faster, more complex data acquisition systems.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include ADC081C021CIMM/NOPB if tape-and-reel packaging is acceptable instead of cut tape. Verify compatibility with ADC081C021CIMF/NOPB regarding package footprint differences between VSSOP and SOIC. Cross-reference with ADC081S101 series only if higher sampling rates are permissible.
