ADC10158CIWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10158CIWM/NOPB is a 10-bit successive approximation register (SAR) analog-to-digital converter manufactured by Texas Instruments. It features an integrated multiplexer supporting 4 or 8 channels, a track-and-hold circuit, and an internal reference. The device operates with a sampling rate of 227 kS/s and accepts differential, pseudo-differential, or single-ended inputs. Power requirements include 4.5 V to 5.5 V for both analog and digital supplies. It utilizes a parallel interface and is housed in a 28-pin SOIC package, functioning within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 4- or 8-channel multiplexer with track-and-hold functionality
• Internal voltage reference eliminates external component requirements
• Supports differential, pseudo-differential, and single-ended input configurations
• Parallel digital interface for direct connection to microprocessors

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Data acquisition modules for sensor interfacing
• Battery-powered instrumentation due to low power consumption characteristics

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific channel configuration (4-channel vs. 8-channel) required for the design, as this affects pin usage. Confirm that the parallel interface timing aligns with the host processor capabilities. Check for end-of-life status, as availability may be limited compared to newer generations. Ensure supply voltages match the specified 4.5 V to 5.5 V range for proper operation.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a moderate-speed, multi-channel ADC with an internal reference is needed. It is suitable for applications where board space is constrained by the integration of the MUX and reference. Compare against the ADC10158CIPW if a smaller package is preferred, noting the pin count difference. Ensure the 227 kS/s sampling rate meets the Nyquist criteria for the target signal bandwidth.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC10158 family of 10-bit SAR ADCs from Texas Instruments. It shares architectural similarities with other devices in the series but differs in package type and channel count options. The 'CI' suffix indicates commercial temperature range operation, while 'WM' denotes the 28-pin SOIC package variant.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family should be verified against the datasheet for electrical parameter equivalence. Consider newer Texas Instruments ADC families if higher resolution or speed is required, though interface compatibility must be assessed.
