TCA0372DWR2

TCA0372DWR2 Description

The TCA0372DWR2 from onsemi is a high-performance dual power operational amplifier (op-amp) in a compact 16-SOIC package, designed for demanding applications requiring robust current output and wide voltage ranges. Operating within a 5V to 40V supply span, this IC delivers 1A output current per channel, making it suitable for driving heavy loads. With a 1.4 MHz gain bandwidth product (GBW) and 1.4V/µs slew rate, it balances speed and power efficiency, while its low 1 mV input offset voltage and 100 nA input bias current ensure precision in signal conditioning. Though marked as obsolete, its reliability and performance remain relevant for legacy designs.

TCA0372DWR2 Features

• High Output Current: 1A per channel enables direct drive of motors, actuators, or transducers.
• Wide Supply Range: 5V–40V operation accommodates diverse industrial and automotive voltages.
• Low Noise & High Precision: 1 mV offset and 100 nA bias current enhance accuracy in sensitive circuits.
• Robust Bandwidth: 1.4 MHz GBW and 1.4V/µs slew rate support dynamic signal processing.
• Surface-Mount Design: 16-SOIC (TR) packaging ensures compact PCB integration.
• Low Quiescent Current: 8mA supply current optimizes power efficiency.

TCA0372DWR2 Applications

Ideal for systems requiring high-current amplification with precision, the TCA0372DWR2 excels in:

• Motor Control: Driving brushed DC or stepper motors in robotics and automation.
