The LT1057CN8#PBF is a dual JFET Input Precision High Speed Operational Amplifier featuring a combination of outstanding high speed and precision specifications. It replaces all the popular bipolar and JFET input dual operational amplifier. In particular, the LT1057 upgrades the performance of systems using the LF412A and OP-215 JFET input duals. When the feedback around the operational amplifier is resistive (RF) a pole will be created with RF, the source resistance and capacitance (RS, CS) and the amplifier input capacitance (CIN ≈ 4pF).The LT1057 may be inserted directly in LF353, LF412, LF442, TL072, TL082 and OP-215 sockets. It has the lowest offset voltage of any dual JFET input operational amplifier.
