ADC08831IMX

Analog To Digital Converters (ADC) Overview

The ADC08831IMX is an 8-bit successive approximation analog-to-digital converter manufactured by Texas Instruments. It features a single input channel and operates with a sampling rate of 250k samples per second. The device supports SPI and DSP data interfaces and utilizes an external voltage reference type. It functions within an analog and digital supply voltage range of 4.5V to 6V. The component is housed in an 8-SOIC package with a width of 3.90mm and is rated for operation between -40°C and 85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrates a configurable input multiplexer supporting single-ended, differential, or pseudo-differential input modes.
• Includes a track/hold function allowing analog voltage variation during the conversion process.
• Automatically enters low power mode when not performing conversions to minimize total power consumption.

Analog To Digital Converters (ADC) Applications

• Remote sensing in noisy environments
• Instrumentation systems
• Embedded systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific manufacturer source, as the ADC08831 was originally developed by National Semiconductor prior to its acquisition by Texas Instruments. Confirm that the IMX suffix corresponds to the SOIC-8 tape and reel packaging variant rather than tube packaging. Ensure compatibility with the required 4.5V to 6V supply rails and check for any relevant design change notices regarding mold compound updates.

Analog To Digital Converters (ADC) Selection Notes

Select this component for applications requiring an 8-bit resolution with a 250ksps sampling rate and serial interface connectivity. It is suitable for designs needing flexible input configurations via its internal multiplexer. Consider the 8-SOIC package dimensions for PCB layout constraints. Verify that the external reference voltage requirement aligns with the system's available reference sources.

Analog To Digital Converters (ADC) Part Context

The ADC08831 belongs to a family of 8-bit serial I/O CMOS A/D converters that also includes the ADC08832. These devices are designed to interface with microcontrollers, PLDs, microprocessors, DSPs, or shift registers using a serial I/O configured to comply with the NSC Microwire serial data exchange standard. The series emphasizes low power consumption through automatic sleep modes.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC08831IMX/NOPB is a verified equivalent part number representing the same functional specifications with RoHS compliance. Other members of the ADC0883x family may offer similar performance but differ in channel count or pinout configuration.
