ADC10154CIWM/NOPB

Analog To Digital Converters (ADC) Overview

The ADC10154CIWM/NOPB is a CMOS 10-bit plus sign successive approximation analog-to-digital converter featuring an integrated multiplexer, track/hold function, and 2.5V band-gap reference. It supports 4-channel (ADC10154) or 8-channel (ADC10158) configurable inputs for single-ended, differential, or pseudo-differential modes. The device operates on a single +5V supply for unipolar ranges (0V to 5V) or dual ±5V supplies for bipolar ranges (-5V to +5V). Key electrical parameters include a maximum conversion time of 4.4 µs at 10-bit resolution, a sampling rate of 166 kHz, and integral linearity error of ±1 LSB max. Power dissipation is 33 mW max in unipolar operation.

Analog To Digital Converters (ADC) Feature Summary

• Configurable 4- or 8-channel analog input multiplexer supporting single-ended, differential, and pseudo-differential modes
• Programmable resolution (8-bit or 10-bit plus sign) with corresponding speed optimization
• Integrated 2.5V band-gap voltage reference with ratiometric or absolute operation capability
• Direct parallel microprocessor interface with tri-state digital outputs

Analog To Digital Converters (ADC) Applications

• Process control systems
• Industrial instrumentation
• Test equipment

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific channel count required: ADC10154 contains 4 channels, while ADC10158 contains 8 channels. Confirm package availability as the CIWM suffix indicates a surface-mount SOIC package. Check current lifecycle status, as older National Semiconductor/TI parts may be discontinued or subject to long lead times from authorized distributors.

Analog To Digital Converters (ADC) Selection Notes

Select based on input channel requirements; use ADC10154 for 4-channel applications and ADC10158 for 8-channel. Ensure power supply configuration matches the application: single +5V for unipolar signals or dual ±5V for bipolar signals. Consider that lower resolution (8-bit) modes offer faster conversion times (3.2 µs max) compared to 10-bit mode (4.4 µs max). Verify clock frequency limits do not exceed 5.0 MHz.

Analog To Digital Converters (ADC) Part Context

This component belongs to the ADC10154/ADC10158 family originally developed by National Semiconductor and later acquired by Texas Instruments. The 'NOPB' suffix typically denotes lead-free/RoHS compliance. The 'C' indicates industrial temperature range (-40°C to +85°C), and 'WM' specifies the plastic small-outline package variant.
