The SR570 can be allocated to various stages of the amplifier to optimize the performance. The low-noise mode places gain in the front end of the amplifier for the best noise performance. Features current gains as large as 1 pA/V. A low noise current amplifier that has an outstanding performance.sr570的可以分给各个段的放大器的性优化。低噪声模式的地方增益放大器的前端为最佳噪声性。特征电流增益为1帕/ V的低噪声电流放大器为大具有优秀的性。
