This module is a wide-voltage amplifier with independently adjustable bias and amplification. It not only amplifies signals but also precisely increases or decreases the DC offset, easily shifting signal levels. Power Protection: Onboard reverse connection protection prevents module damage due to incorrect power supply polarity. Gain Adjustment: The gain potentiometer allows compatible with linear amplification of the input signal from 1 to 13 times. Bias Adjustment: The bias potentiometer allows compatible with the addition of a positive or negative DC voltage to the output signal. With a ±15V power supply, a maximum DC offset of ±11V can be added. Suitable compatible with various analog signal conditioning applications, such as unipolar to bipolar conversion, sensor signal amplification, and ADC/DAC driving. Module Type: Voltage Amplifier (Bias and Gain Adjustable) Power Supply Range: ±5V to ±18V (±15V or ±12V recommended) Input Impedance: 20KΩ Gain Range: 1x - 13x (Continuously adjustable via on-board potentiometer) Bandwidth: 2MHz (Gain increases, bandwidth decreases accordingly) Bias Adjustment Range: ±11V (with ±15V power supply) Input/Output Voltage Range: ±13V (with ±15V power supply, limited by supply voltage) Output Drive Capability: 40mA (Max) Output Impedance: Low Impedance Output Input/Output Type: Single-Ended Input/Output Interface: Default SMA connector (with reserved terminal blocks compatible with easy low-frequency testing and connection) Color: Black Material: PCB Package Contents: 1*DC Bias Adjustable Amplifier Module Only the above package content, other products are not included. Note: Light reflection and different displays may cause the color of the item in the picture a little different from the real thing. The measurement allowed error is +/- 1-3cm.
