ADC081S051CIMFX

Analog To Digital Converters (ADC) Overview

The ADC081S051CIMFX 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 a SPI/QSPI/MICROWIRE/DSP compatible interface for data output. The component is housed in a compact 6-lead SOT-23 package and ensures reliable operation across the industrial temperature range of −40°C to +85°C.

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific ordering suffix 'CIMFX' against the manufacturer's current product folder to confirm availability status and exact packaging details. Confirm RoHS compliance requirements as older production runs may differ. Ensure the design accounts for the ESD protection limitations by using proper handling procedures during assembly.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution and up to 500 ksps throughput are sufficient for the application. Consider the SOT-23-6 package size constraints and the requirement for a single-ended input signal. Verify that the system logic levels are compatible with the digital input voltage range of -0.3V to 5.25V regardless of the analog supply voltage.

Analog To Digital Converters (ADC) Part Context

The ADC081S051 belongs to the Texas Instruments ADC081 family of 8-bit A/D converters. It is pin-compatible with other variants in the series such as the ADC081S021 (50-200 ksps) and ADC081S101 (500 ksps to 1 Msps), allowing for design flexibility regarding speed requirements while maintaining the same footprint and interface compatibility.

Analog To Digital Converters (ADC) Replacement Considerations

Pin-compatible alternatives within the same family include the ADC081S021 for lower speed applications and the ADC081S101 for higher speed requirements. These devices share identical pinouts and functional compatibility.
