The ADC124S021CIMMX from Texas Instruments is a 12-bit, 200 kSPS successive approximation register (SAR) analog-to-digital converter (ADC) designed for precision signal acquisition in embedded systems. Housed in a compact 10-VSSOP package, this single-channel ADC operates with a 2.7V to 5.25V dual supply range (analog and digital), making it suitable for low-power and mixed-voltage applications. It features a single-ended input architecture with a 1:1 sample-and-hold (S/H) to ADC ratio, ensuring accurate signal capture. The device communicates via SPI/DSP-compatible serial interface, enabling seamless integration with microcontrollers and digital signal processors. Although marked as obsolete, it remains relevant for legacy designs requiring stable performance in industrial and consumer electronics.
This ADC is well-suited for:
The ADC124S021CIMMX offers a balanced combination of speed, resolution, and integration, making it a pragmatic choice for cost-sensitive, mixed-signal applications. Its obsolete status may limit new designs, but its robust performance, ease of interfacing, and compact footprint ensure continued utility in legacy and low-volume production environments. Engineers valuing simplicity and reliability in moderate-performance ADCs will find this TI converter a dependable solution.
