LF157

宽带宽单J-FET运算放大器 WIDE BANDWIDTH SINGLE J-FET OPERATIONAL AMPLIFIERS

DESCRIPTION

These circuits are monolithic J-FET input operational amplifiers incorporating well matched, high voltage J-FET on the same chip with standard bipolar transistors.

HIGH INPUT IMPEDANCE J-FET INPUT STAGE

HIGH SPEED J-FET OP-AMPs : up to 20MHz, 50V/µs

OFFSET VOLTAGEADJUSTMENT DOES NOT DEGRADE DRIFT OR COMMON-MODE REJECTION AS IN MOST OF MONOLITHIC AMPLIFIERS

INTERNAL COMPENSATION AND LARGE DIFFERENTIAL INPUT VOLTAGECAPABILITY UP TO VCC+
