ADC124S021CIMMX/NOPB

Analog To Digital Converters (ADC) Overview

The ADC124S021CIMMX/NOPB is a four-channel, 12-bit analog-to-digital converter (ADC) manufactured by Texas Instruments. It utilizes a successive approximation register (SAR) architecture and supports sampling rates ranging from 50 ksps to 200 ksps. The device features single-ended inputs and communicates via a standard SPI-compatible interface. It operates on a single power supply voltage between 2.7 V and 5.25 V for both analog and digital domains. The component is housed in a TSSOP-16 package and is rated for operation within a temperature range of -40°C to +85°C.

Analog To Digital Converters (ADC) Feature Summary

• Four independent input channels enable simultaneous multi-point signal acquisition without external multiplexing.
• High-speed serial interface allows direct connection to microcontrollers and DSPs with minimal pin count.
• Integrated sample-and-hold circuitry ensures accurate data conversion across the specified bandwidth.

Analog To Digital Converters (ADC) Applications

• Portable instrumentation requiring low power consumption and multiple sensor inputs
• Industrial process control systems utilizing single-ended sensor signals
• Data acquisition modules for environmental monitoring

Analog To Digital Converters (ADC) Procurement Notes

Verify the complete part number including the suffix /NOPB to confirm lead-free status and RoHS compliance. Ensure the ordering code matches the specific package variant required for your PCB layout. Cross-reference the manufacturer's latest datasheet revision to confirm pinout and electrical specifications before finalizing procurement orders.

Analog To Digital Converters (ADC) Selection Notes

Select this component when four single-ended channels are required at speeds up to 200 ksps. Consider alternative models if differential input capability or higher resolution is necessary. Verify that the system clock requirements align with the SPI interface timing constraints defined in the technical documentation.

Analog To Digital Converters (ADC) Part Context

This part belongs to the ADC124S family of 12-bit SAR converters. It shares architectural similarities with the ADC124S051 but offers lower maximum sampling rates. The device serves as a cost-effective solution for applications needing moderate speed and multiple inputs in a compact surface-mount package.

Analog To Digital Converters (ADC) Replacement Considerations

The ADC124S021CIMMX is the base equivalent. Check for availability of the NOPB variant for environmental compliance. Other family members like ADC124S051 offer higher speeds but may require different thermal management.
