Module Description

(1) Single power supply with wide voltage operation, reverse connection protection, and large-capacity filter capacitor, suitable for environments with strong interference and large power fluctuations;

(2) The module adopts high-performance, high-speed, low-noise charge pump negative voltage conversion, allowing the amplifier to have a negative half-axis power rail and easily achieve 10V pp amplitude voltage output; (Note: Most online products use ICL7660 charge pump to reverse negative voltage, whose low switching frequency will introduce interference into the amplifier. When the instrument amplifier works at high gain, the switching frequency of ICL7660 is within the effective bandwidth, so interference is inevitable. Therefore, when designing such amplifiers, in addition to reasonable power supply filtering, a high-speed switching frequency negative voltage converter should be used to pull a significant spectral distance from the effective bandwidth of the amplifier, making post-filter processing easier.)

(3) The module adopts 3.81 plug-in wiring design, which is more practical in actual applications;

(4) The module can realize the adjustment of any gain value within the range, output zero adjustment, and bias voltage adjustment and other basic functions
