ADC10158CIWMX

Analog To Digital Converters (ADC) Overview

The ADC10158CIWMX/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 on a single 4.5 V to 5.5 V supply for both analog and digital domains. It delivers a sampling rate of 227 kS/s with a parallel interface. Key performance metrics include a gain error of 1.5 LSB and integral nonlinearity (INL) of 1 LSB. The component is housed in a 28-SOIC package and functions within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• 10-bit SAR architecture with 227 kS/s sampling rate
• Integrated 4- or 8-channel multiplexer and track-and-hold
• Internal voltage reference reduces external component count
• Parallel data interface for direct microcontroller connection

Analog To Digital Converters (ADC) Applications

• Industrial process control systems requiring multi-channel signal acquisition
• Portable instrumentation utilizing single-supply operation
• Data acquisition modules for sensor interfacing

Analog To Digital Converters (ADC) Procurement Notes

Verify the specific suffix configuration, as the NOPB designation indicates lead-free and RoHS compliance. Confirm availability status, as this part number may be discontinued or subject to long lead times depending on current inventory levels. Ensure the selected package variant matches the PCB footprint requirements for the 28-SOIC housing.

Analog To Digital Converters (ADC) Selection Notes

Select this component when a moderate resolution of 10 bits is sufficient for the application's accuracy needs. The internal reference simplifies design compared to external reference solutions. Consider the parallel interface complexity if pin count is constrained, as serial alternatives like the ADC12130 series offer fewer pins but different speed characteristics.

Analog To Digital Converters (ADC) Part Context

This device belongs to the ADC10158 family of high-speed, low-power ADCs from Texas Instruments. It shares architectural similarities with other SAR converters in the portfolio but is distinguished by its specific combination of channel count, sampling speed, and integrated peripherals. It serves as a bridge between high-resolution slow converters and ultra-high-speed specialized ADCs.

Analog To Digital Converters (ADC) Replacement Considerations

Direct substitutes include the ADC10158CIMMX/NOPB, which offers the same functionality in a smaller QFN package. For applications requiring higher resolution, the ADC12130 series provides 12-bit performance with a serial interface, though it requires verification of pin compatibility and software driver adjustments.
