LF147/LF347 Wide Bandwidth Quad JFET Input Operational Amplifiers

Check for Samples: LF147, LF347-N

FEATURES

DESCRIPTION

The LF147 is a low cost, high speed quad JFET input

operational amplifier with an internally trimmed input

offset voltage ( BI-FET II™ technology). The device

requires a low supply current and yet maintains a

large gain bandwidth product and a fast slew rate. In

addition, well matched high voltage JFET input

devices provide very low input bias and offset

currents. The LF147 is pin compatible with the

standard LM148. This feature allows designers to

immediately upgrade the overall performance of

existing LF148 and LM124 designs.

•

Internally Trimmed Offset Voltage: 5 mV max

Low Input Bias Current: 50 pA

Low Input Noise Current: 0.01 pA/√Hz

Wide Gain Bandwidth: 4 MHz

•

High Slew Rate: 13 V/μs

Low Supply Current: 7.2 mA

High Input Impedance: 10¹²Ω

Low Total Harmonic Distortion: ≤0.02%

Low 1/f Noise Corner: 50 Hz

The LF147 may be used in applications such as high

speed integrators, fast D/A converters, sample-and-

hold circuits and many other circuits requiring low

input offset voltage, low input bias current, high input

impedance, high slew rate and wide bandwidth. The

device has low noise and offset voltage drift.

Fast Settling Time to 0.01%: 2 μs
