2PCS LC7 Dual Op Amp Class A JFET High Current Discrete Double Operational Amplifiers with Low Distortion

The LC7 dual operational amplifier modules is Lower noise and distortion discrete operational amplifier, suitable for front-end amplification, DACIV conversion, LPF filtering

Various uses such as wave filters.

Its design dimensions effectively avoid decoupling capacitors on both sides of the socket, ensuring smooth installation and operation.

Use 6 in total expensive low-noise JFET2SK2145 as input differential amplifiers Amplification, ON transistor as mirror constant current source, 1% resistor. This version does not have an adjustable potentiometer and can also be used To maintain an extremely low output offset voltage (less than 10mV).

Megaohm level high impedance input enhances the ability to amplify and capture weak signals without losing details. When maintaining low noise and distortion, the measured THD+N is 0.00003% @ 1KHz (due to the instrument's own loss, True degree+noise 0.00006%).

With high output current, the distortion is less than 0.002% when the output current is 100mA, which is higher than previous modules

Reduced by 10 times, while the output current of a regular operational amplifier has already burned out or been protected.

High compatibility, can be used for IV, LPF, and amplifier circuits, and can also be used for buffering and 1x amplification to ensure stable operation

Make it.
