ADC0838CCWM

Analog To Digital Converters (ADC) Overview

The ADC0838CCWM is an 8-bit successive approximation analog-to-digital converter (ADC) manufactured by Texas Instruments. It features a software-configurable multiplexer supporting up to eight input channels, which can be configured for single-ended, differential, or pseudo-differential operation. The device operates on a single 5 VDC supply with a voltage range of 4.5 V to 6.3 V and consumes 15 mW of power. It utilizes a TI MICROWIRE-compatible serial interface for data exchange. The component is housed in a 20-pin SOIC package and is rated for commercial operating temperatures between 0°C and +70°C.

Analog To Digital Converters (ADC) Applications

• Remote data acquisition systems utilizing serial digital data links
• Industrial process control requiring multi-channel signal monitoring
• Microprocessor peripheral interfaces for sensor data collection

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix 'CCWM' against current manufacturer documentation to confirm availability status and lead times. Ensure that the commercial temperature rating (0°C to +70°C) aligns with the intended environmental operating conditions. Cross-reference pinouts and electrical specifications with the latest SNAS531B datasheet revision prior to finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-bit resolution with multiple configurable analog inputs is required. The ADC0838CCWM is suitable for applications needing flexible input modes, including differential pairs or pseudo-differential setups relative to a common reference. Ensure the system clock frequency remains within the 10 kHz to 400 kHz range and that the supply voltage stays between 4.5 V and 6.3 V for proper operation.

Analog To Digital Converters (ADC) Part Context

The ADC0838CCWM belongs to the ADC0831-N series of 8-bit serial I/O A/D converters. This family includes variants with different channel counts, such as the ADC0831 (1 channel), ADC0832 (2 channels), and ADC0834 (4 channels). The 'CCWM' designation specifically identifies the commercial temperature grade and the 20-pin SOIC package format containing the 8-channel multiplexer.

Analog To Digital Converters (ADC) Replacement Considerations

Direct replacement options include other members of the ADC083x-N family, such as the ADC0834CCN for 4-channel applications. Verify that any substitute maintains compatibility with the TI MICROWIRE protocol and matches the required package dimensions and pinout configuration.
