Adjustable Gain Gain can be set from 25x to 125x, enabling precise amplification of lowlevel signals and compatibility with microcontroller ADC inputs. Railtorail Output Delivers up to 5 V peaktopeak output without distortion, providing ample headroom for a wide range of applications and signal levels. Versatile Applications Suitable for stm and other development boards, offering a flexible solution for audio enthusiasts and diyers. Easy to Connect GND to ground and VCC to 2.4–5 V DC, enabling straightforward integration into different systems. Use scenarios Prototyping with stm and other development boards: condition sensor or audio signals before ADC input with adjustable gain and clean output. DIY audio projects: amplify small audio signals with stable, railtorail performance for reliable listening levels. Educational or lab setups: explore signal conditioning, gain adjustment, and railtorail output behavior in practical experiments.
