RTA-500 module is a general-purpose inverting amplifier with the AC coupled input and gain regulated with a potentiometer. This device is designed as an analog front-end for the popular analog-digital converters embedded in the microcontrollers. Wide input signal voltage range and signal polarization allows to use a single supply ADC to sample the bipolar signal sources.
The amplifier module is compatible with the ADCs embedded in ARM (STM discovery, LPC boards, etc.) and ATMEGA (ARDUINO boards) microcontrollers.
Rail to rail output allow to sample signals from gnd to supply voltage without loss of input range. Input bias to half of the supply voltage allof sensing both the unipolar and bipolar signals.
Amplifier was built from non piezoelectric components to avoid noises due mechanical vibrations.
Amplifier can be used for
- ultrasonic or IR transducers applications,
- voltage and capacity measurement,
- strain gauge or piezoelectric sensors,
- as analog and digital signals amplifier.
