This device is a low cost, high speed, JFET input

23

•

Input Offset Voltage Drift: 20

μV/°C (Max)

operational amplifier with very low input offset voltage

•

Low Input Bias Current: 50 pA (Typ)

and ensured input offset voltage drift. It requires low

•

Low Input Noise Current: 0.01 pA/

√Hz (Typ)

supply current yet maintains a large gain bandwidth

product and fast slew rate. In addition, well matched

•

Wide Gain Bandwidth: 2.7 MHz (Min)

high voltage JFET input devices provide very low

•

High Slew Rate: 8V/

μs (Min)

input bias and offset currents. The LF412 dual is pin

•

High Input Impedance: 1012

Ω

compatible with the LM1558, allowing designers to

immediately upgrade the overall performance of

•

Low Total Harmonic Distortion <0.02%

existing designs.

•

Low 1/f Noise Corner: 50 Hz

This amplifier may be used in applications such as

•

Fast Settling Time to 0.01%: 2

μs

high speed integrators, fast D/A converters, sample

and hold circuits and many other circuits requiring low

input offset voltage and drift, low input bias current,

high input impedance, high slew rate and wide

bandwidth.
