Power supply: 5V-24V can be, but depends on how much the baby with the voltage output (if the customer requires output 5V voltage, then the AD62X series of chips is about ± 3.8V power supply, the regulator chip itself has a pressure difference, so it is recommended that the voltage is higher than 12V single Power supply is better)

Bandwidth: AD620/623 is lower than 50KHz at high gain and greater than 1MHz at low gain Input signal type: single-ended signal or differential signal

The maximum magnification: more than 2000 times (actual measurement), due to the gain assembly resulting in greater fluctuations in the waveform band, it is recommended to use high-gain multi-stage amplification

♥Introduction: The AD620 is a low-cost, high-accuracy instrumentation amplifier that requires only one external resistor to set the gain over a gain range of 1 to 10,000. Ideal for portable (or remote) applications. With high accuracy, low offset voltage, and low offset drift, the AD620 is ideal for precision data acquisition systems such as electronic scales and sensor interfaces. Also features low noise, low input bias current, and low power consumption. The module has a fixed voltage output.

Name: THS4131 Fully Differential Amplifier Size: 45mm X 34mm Supply Voltage Range: 5V Single Supply ±15V Dual Supply

This module can implement single-ended to differential, single-ended input, and double-ended output. Has high performance, low noise, wide power supply voltage range and other advantages.

The THS413x consists of a true fully differential signal path from input to output. This design produced excellent common-mode noise suppression wells that improved total harmonic distortion.

Name: AD8130 Differential Amplifier Size: 43mm X 38mm Supply voltage range: ±5V~±12V

The differential-to-single-ended amplifier, which has a 270-MHz bandwidth and a very high common-mode rejection ratio (CMRR) at high frequencies, can also be effectively used as a high-speed instrumentation amplifier or to convert a differential signal to a single-ended signal.

Differential amplifiers can process single-ended inputs as interactive differential outputs or treat differential inputs as differential outputs. These amplifiers have two independent feedback loops that control the differential and common-film output voltages, respectively.

Usually the CTRL pin is connected to the MUTE pin of Bluetooth.

The amplifier board is in ACF-1 mode by default. When using the CTRL mode setting, solder R5 off.
