ADC08831IN/NOPB

Analog To Digital Converters (ADC) Overview

The ADC08831IN/NOPB is an 8-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features a single input channel with configurable multiplexer and sample/hold functions, supporting differential, pseudo-differential, and single-ended input types. The device operates on a single supply voltage ranging from 4.5 V to 6 V for both analog and digital domains. It utilizes a 3-wire serial interface compatible with SPI and Microwire standards. The component is housed in an 8-pin MDIP package and is rated for operation within a temperature range of 0°C to +70°C.

Analog To Digital Converters (ADC) Feature Summary

• Configurable input multiplexer supports multiple signal configurations including single-ended, differential, and pseudo-differential modes.
• Integrated track-and-hold function maintains analog voltage stability during the conversion process.
• Low power consumption achieved through automatic entry into low-power mode when conversions are inactive.

Analog To Digital Converters (ADC) Applications

• Remote sensing in noisy environments
• General instrumentation systems
• Embedded control systems

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'IN' corresponds to the 8-pin MDIP plastic DIP package rather than surface-mount variants like IMX or IMM. Confirm the operating temperature grade matches the industrial requirement, as this variant is specified for 0°C to +70°C. Ensure the NOPB designation confirms lead-free and RoHS compliance status prior to integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with up to 250 kSPS sampling rate is sufficient for the application. It is suitable for designs requiring a simple serial interface without complex parallel data buses. Consider the 4.5 V to 6 V supply constraint; if lower voltage operation is required, alternative parts such as the ADCV08832 series should be evaluated instead.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC08831/ADC08832 family of 8-bit serial I/O CMOS A/D converters originally developed by National Semiconductor and acquired by Texas Instruments. The family provides a cost-effective solution for applications needing moderate speed and resolution with minimal external components.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC08832 is the primary functional substitute within the same family, offering identical performance but with two input channels instead of one. Verify pin compatibility and software configuration differences regarding channel selection before substitution.
