ADC10154CIWMX

Analog To Digital Converters (ADC) Overview

The ADC10154CIWMX 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 operates on a single +5V supply for unipolar or dual ±5V supplies for bipolar operation. The device supports programmable resolution (8-bit or 10-bit) and output data formats. Key electrical specifications 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. It utilizes a parallel interface with interrupt-driven readout.

Analog To Digital Converters (ADC) Procurement Notes

Verify component authenticity through authorized distributors or manufacturer channels. Confirm package integrity and pin alignment against the SO-28 specification. Check manufacturing date codes to ensure compliance with current environmental standards. Review datasheet revision history for any functional updates prior to integration.

Analog To Digital Converters (ADC) Selection Notes

Select this component when an 8-channel MUX is required alongside high-speed conversion. Choose the 10-bit mode for precision applications requiring 166 kHz throughput. Use the 8-bit mode for faster acquisition at 207 kHz. Ensure power supply decoupling meets the 0.1 µF ceramic and 10 µF tantalum requirements specified in the datasheet.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC1015x family from National Semiconductor, now Texas Instruments. The ADC10154 variant provides 4 channels, while the ADC10158 provides 8 channels. The CIWM suffix indicates industrial temperature range (-40°C to +85°C) and SOIC-28 surface mount packaging.

Analog To Digital Converters (ADC) Replacement Considerations

Direct pin-compatible replacements within the same family include the ADC10158CIN (DIP-28) or ADC10158CIWM (SOIC-28). Verify that the substitute maintains the 8-channel multiplexer configuration and identical pinout for DB0-DB7, CS, RD, WR, and INT signals.
