01 pA/√Hz Typical • Low Total Harmonic Distortion • Low Supply Current: 8 mA Typical • Gain Bandwidth: 3 MHz Typical • High Slew Rate: 13 V/ms Typical 2 Applications • Motor Integrated Systems: UPS • Drives and Control Solutions: AC Inverters and VF Drives • Renewables: Solar Inverters • Pro Audio Mixers • Oscilloscopes 3 Description The LF347 and LF347B devices are low-cost, highspeed, JFET-input operational amplifiers.
They require low supply current yet maintain a large gainbandwidth product and a fast slew rate.
In addition, their matched high-voltage JFET inputs provide very low input bias and offset current.
The LF347 and LF347B can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits, and many other circuits.
The LF347 and LF347B devices are characterized for operation from 0°C to 70°C.
