2pcs Dual Discrete Op Amp HiFi Audio Preamp Operational Amplifier OPAMP Replace ad827
Main highlights- 5.Description Low Distortion: 0.0008% High Speed: conversion rate(120V/us) and bandwidth(8MHz) Low Noise: 4nV/√Hz High open-loop gain: 120dB(600Ω) BJT Input: IB =30pA Power Range: ±12V-±18V (standard ±15V) Application Area
- 4. Large dynamic range, the minimum value of the input signal is limited by noise, for both voltage and current, and the maximum value of the output signal .
- 3. Simplify the circuit operation by adopting the principle of transconductance. The principle of transconductance describes that once a transconductance loop occurs in a circuit, there exists a constraint relationship between the currents of the transistors in the loop.
- 2. Small nonlinear distortion, in the current mode circuit, because of the successful use of matching technology, in order to meet the basic requirements of the current transmission, as far as possible to make the circuit symmetrical.
- 1. Wide bandwidth and high speed. In current mode circuits, because there is no need to consider the size of the voltage swing, the tube can be inter-pole capacitance, in the low-impedance node, so that the upper frequency is very high, almost similar to Ft.
