TEXAS INSTRUMENTS LF347BN 运算放大器, 四路, 4 MHz, 4个放大器, 13 V/µs, 8V 至 36V, DIP, 14 引脚
The is a wide-bandwidth Quad JFET-input Operational Amplifier for use with oscilloscopes. It requires low supply current yet maintains a large gain-bandwidth product and a fast slew rate. In addition, their matched high-voltage JFET input provides very low input bias and offset current. The LF347B can be used in applications such as high-speed integrators, digital-to-analog converters, sample-and-hold circuits and many other circuits.
