ADC10154CIWMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10154CIWMX/NOPB is a CMOS 10-bit plus sign successive approximation analog-to-digital converter featuring an 8-channel multiplexer, track/hold function, and internal 2.5V band-gap reference. It supports single-ended, differential, or pseudo-differential input configurations via software control. The device operates on a single +5V supply for unipolar inputs (0V to 5V) or dual ±5V supplies for bipolar inputs (-5V to +5V). Key electrical parameters include a maximum integral linearity error of ±1 LSB, a conversion time of 4.4 µs in 10-bit mode, and a sampling rate of 166 kHz. It utilizes a parallel interface with programmable resolution and output data formatting.

Analog To Digital Converters (ADC) Feature Summary

• Integrated 8-channel configurable multiplexer supporting single-ended, differential, and pseudo-differential modes
• Internal 2.5V band-gap voltage reference with ratiometric or absolute operation capability
• Programmable resolution (8-bit or 10-bit plus sign) allowing trade-offs between speed and precision
• Parallel digital interface with tri-state outputs and interrupt signal for conversion completion

Analog To Digital Converters (ADC) Applications

• Process control systems requiring multi-channel signal acquisition
• Industrial instrumentation and data acquisition modules
• Test equipment involving analog signal digitization

Analog To Digital Converters (ADC) Procurement Notes

Verify the component status as discontinued by Texas Instruments. Confirm that the NOPB suffix indicates lead-free/RoHS compliance relative to the original National Semiconductor specification. Ensure the CIWM suffix matches the required industrial temperature range (-40°C to +85°C) and SOIC-28 package type for your design integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel MUX is required alongside the ADC to reduce external circuitry. Choose the 10-bit plus sign mode for bipolar applications requiring sign indication, or 8-bit mode for higher throughput needs. Ensure the system clock frequency does not exceed 5.0 MHz to maintain specified timing constraints and accuracy limits.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC10154/ADC10158 family originally developed by National Semiconductor before its acquisition by Texas Instruments. The ADC10154 variant provides 4 channels, while the ADC10158 provides 8 channels. The CIWM designation specifically identifies the industrial temperature grade and surface-mount SOIC-28 packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Publicly confirmed substitute part numbers are not available in the provided documentation. Due to the discontinued status, direct pin-compatible replacements from other manufacturers should be evaluated based on specific electrical parameter matching rather than guaranteed cross-reference lists.
