LF156-LF256

These circuits aremonolithic J-FET LF156-LF256 input operational amplifiers incorporatingwell matched, high voltage J-FET on the same chip with standardbipolar transistors. This amplifiers feature low input bias and offset currents, low input offset voltage and input offset voltage drift,coupledwith offsetadjustwhichdoesnotdegrade drift or common-mode rejection.It is could be used in: (1) Precision high speed integrators .; (2)Fast d/a and converters .; (3)High impedance buffers ; (4)Wideband, lownoise, lowdrift amplifiers Logarithimicamplifiers Photocell amplifiers ; (5)Sampleand hold circuits.

Features of the LF156-LF256 are:(1)High input impedance j-fet input stage ; (2)High speed j-fet op-amps : up to 20MHz,50V/ms Offsetvoltageadjustmentdoesnot degradedrift or common-mode rejection as in most of monolithic amplifiers ; (3)Internal compensation and large differential inputvoltagecapability (up to vcc +).

The absolute maximum ratings of the LF156-LF256can be summarized as:(1)Supply Voltage : ±22V;(2)Input Voltage : ±20V;(3)Differential Input Voltage: ±40V; (4)Power Dissipation: 570mW;(5)storage temperature:-65°C to +150°C;(6)Operating Temperature :-55 to 125°C.
