LN2051 chip is a high precision, low noise, low drift amplifier, its pin parameters include positive and negative power supply, input signal port, output signal port, control port and reference voltage port.
The input signal ports include positive and negative input ports and ground ports, the output signal ports include positive and negative output ports and ground ports, and the control ports include gain regulation ports and power control ports.
The reference voltage port is used to provide a reference voltage so that the amplifier can achieve high precision amplification. These pin parameters are reasonably designed, reasonably laid out and reliably used, which can achieve high performance signal amplification in various applications.
