LT1057/LT1058 Dual and Quad, JFET Input Precision High Speed Op Amps
FEATURES DESCRIPTION
n 14V/µs Slew Rate: 10V/µs Min The LT®1057 is a matched JFET input dual op amp in n 5MHz Gain-Bandwidth Product the industry standard 8-pin configuration, featuring a n Fast Settling Time: 1.3µs to 0.02% combination of outstanding high speed and precision n 150µV Offset Voltage (LT1057): 450µV Max specifications. It replaces all the popular bipolar and JFET n 180µV Offset Voltage (LT1058): 600µV Max input dual op amps. In particular, the LT1057 upgrades the n 2µV/°C VOS Drift: 7µV/°C Max performance of systems using the LF412A and OP-215 n 50pA Bias Current at 70°C JFET input duals. n Low Voltage Noise: The LT1058 is the lowest offset quad JFET input operational 13nV/√Hz at 1kHz amplifier in the standard 14-pin configuration. It offers 26nV/√Hz at 10Hz significant accuracy improvement over presently available JFET input quad operational amplifiers. The LT1058 can
APPLICATIONS
replace four single precision JFET input op amps, while saving board space, power dissipation and cost. n Precision, High Speed Instrumentation n Both the LT1057 and LT1058 are available in the plastic Fast, Precision Sample-and-Hold n PDIP package and the surface mount SO package.
