ADC081S051CIMF/NOPB

Analog To Digital Converters (ADC) Overview

The ADC081S051CIMF/NOPB is an 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single-ended input and operates with supply voltages ranging from 2.7V to 5.25V for both analog and digital domains. The device supports sampling rates up to 500k samples per second and utilizes a standard SPI or DSP-compatible serial interface for data transfer. It is housed in a compact SOT-23-6 surface-mount package and is rated for operation within a temperature range of -40°C to 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a high-speed SAR ADC core with a sample-and-hold circuit for accurate signal acquisition.
• Supports flexible digital interfacing through compatibility with standard SPI and DSP protocols.
• Operates efficiently across a wide voltage range, enabling use in battery-powered and low-voltage systems.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power consumption and small form factor
• Battery-operated measurement devices
• Industrial process control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix configuration when ordering, as the NOPB designation indicates lead-free and RoHS-compliant manufacturing. Confirm that the SOT-23-6 package dimensions align with your PCB footprint requirements. Ensure that the operating voltage range of 2.7V to 5.25V matches your system's power supply rails to guarantee proper functionality and avoid damage.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and 500ksps sampling rate are sufficient for the application. Consider the SOT-23-6 package if space constraints are critical. Evaluate the need for single-ended inputs versus differential requirements. Compare performance against higher-resolution alternatives if precision is paramount, or faster converters if bandwidth demands exceed 500ksps.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC081 family of micro-power analog-to-digital converters. It shares architectural similarities with other members like the ADC081S101 but offers lower sampling speeds. The NOPB suffix distinguishes it from older non-RoHS versions, ensuring compliance with modern environmental standards while maintaining functional equivalence to previous iterations.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC081S051CIMF is listed as obsolete, with the ADC081S051CIMF/NOPB serving as the direct replacement. Verify pinout compatibility when transitioning from non-NOPB variants. No alternative part numbers are publicly confirmed as direct substitutes in the provided documentation.
