1 / 21 page LF147, LF347-N www.ti.com SNOSBH1D – MAY 1999 – REVISED MARCH 2013 LF147/LF347 Wide Bandwidth Quad JFET Input Operational Amplifiers Check for Samples: LF147, LF347-N 1 FEATURES DESCRIPTION The LF147 is a low cost, high speed quad JFET input 23 • Internally Trimmed Offset Voltage: 5 mV max operational amplifier with an internally trimmed input • Low Input Bias Current: 50 pA offset voltage ( BI-FET II™ technology). The device • Low Input Noise Current: 0.01 pA/ √Hz requires a low supply current and yet maintains a large gain bandwidth product and a fast slew rate. In • Wide Gain Bandwidth: 4 MHz addition, well matched high voltage JFET input • High Slew Rate: 13 V/ μs devices provide very low input bias and offset • Low Supply Current: 7.2 mA currents. The LF147 is pin compatible with the standard LM148. This feature allows designers to • High Input Impedance: 1012 Ω immediately upgrade the overall performance of • Low Total Harmonic Distortion: ≤0.02% existing LF148 and LM124 designs. • Low 1/f Noise Corner: 50 Hz The LF147 may be used in applications such as high • Fast Settling Time to 0.01%: 2 μs 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. Simplified Schematic Connection Diagram ¼ Quad LF147 available as per JM38510/11906.
