ADC081S051CIMF

Analog To Digital Converters (ADC) Overview

The ADC081S051CIMF is a low-power, single-channel CMOS 8-bit analog-to-digital converter featuring a high-speed serial interface. Based on a successive-approximation register architecture with an internal track-and-hold circuit, it operates over a sample rate range of 200 ksps to 500 ksps. The device supports a single power supply ranging from 2.7V to 5.25V and consumes 1.6 mW at 3.6V or 8.5 mW at 5.25V. It utilizes SPI/QSPI/MICROWIRE/DSP compatible digital interfaces and is housed in a compact 6-lead SOT-23 package.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors as the part may be obsolete. Confirm RoHS compliance status for specific manufacturing lots. Ensure proper ESD handling procedures during storage and assembly due to limited built-in protection. Check for availability of pin-compatible alternatives if supply constraints exist.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and up to 500 ksps throughput are required in a small footprint. Ensure the system clock frequency falls between 4 MHz and 10 MHz for guaranteed electrical performance. Verify that the analog input voltage remains within the 0V to VA range to prevent ESD diode conduction.

Analog To Digital Converters (ADC) Part Context

This device belongs to the Texas Instruments ADC081 family of single-channel ADCs. It shares pin compatibility with other resolutions and speeds in the series, such as the ADC081S021 and ADC081S101. The CIMF suffix indicates the SOT-23-6 package variant designed for surface-mount applications.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives include the ADC081S021 (50–200 ksps) and ADC081S101 (500 ksps–1 Msps). These devices maintain identical pinouts and functionality while offering different speed specifications.
