STMicroelectronics X-NUCLEO-IKA01A1 X-NUCLEO Operational Amplifier Expansion Board for Arduino UNO Connector, STM32

The X-NUCLEO-IKA01A1 is a multi-functional expansion board based on STMicroelectronics TSZ124 high accuracy zero drift micropower 5 V operational amplifier. An affordable and easy-to-use micropower, precision operational amplifier for STM32 Nucleo Development Board projects. The board connectors are compatible with the Arduino UNO R3 connectors. These features make an ideal analogue front-end (AFE) by conditioning signals for sensor interfaces and battery-powered portable applications. The current-sensing configuration allows application measurements with a Micro USB port. The TSZ124 operational amplifier has high accuracy and stability for an instrumentation amplifier structure. The expansion board also contains a TSU104 nanopower op-amp, and a TSV734 micropower op-amp for mobile applications.

Seven predefined configurations:
Instrumentation amplifier structure
Current sensing with or without USB
Photodiode/ultraviolet (UV) current sensing
Buffer
Full wave rectifier
Constant current LED driver
Window comparator
Prototyping area is available
