... C and 500pA at 125 C. The 150 V maximum offset voltage specification is the best available on any JFET input operational amplifier. The LT1055 and LT1056 are differentiated by their operat- ing currents. The lower power dissipation LT1055 achieves lower bias and offset currents and offset voltage. The ...

... Note 1: Offset voltage is measured under two different conditions: (a) approximately 0.5 seconds after application of power; ( only, with the chip heated to approximately 38 C for the LT1055 and for the LT1056, to account for chip temperature rise when the device is fully warmed up. Note 2: 10Hz noise voltage density is sample tested on every lot of A grades ...

... V OFFSET TRIM OUT The LT1055/LT1056 has the lowest offset voltage of any JFET input op amp available today. However, the offset voltage and its drift with time and temperature are still not as good as on the best bipolar amplifiers because the transconductance of FETs is considerably lower than that of bipolar transistors ...

... Consequently, for optimum low frequency noise, chip temperature should be minimized. For example, operating an LT1056 at 5V supplies or with a 20 C/W case-to- ambient heat sink reduces 0.1Hz to 10Hz noise from typically 2 15V, free-air) to 1.5 V P-P the noise of an LT1055 will be 1 ...

... This can cause lock-up in servo systems. As shown below, the LT1055/LT1056 does not have this problem due to unique phase reversal protection circuitry (Q1 on simplified schematic). Input ...
