LF347DR Description

Short technical summary and product information.

The LF347DR from Texas Instruments is a quad JFET-input operational amplifier designed for high-speed applications. It offers a typical gain bandwidth of 3 MHz and a fast slew rate of 13 V/µs, making it suitable for circuits requiring quick signal response.

 

This operational amplifier requires low supply current, typically 8 mA, while maintaining its high-speed characteristics. The JFET inputs provide very low input bias and offset current, typically 50 pA. The device operates over a temperature range of 0°C to 70°C.

 

The LF347DR is housed in a 14-pin SOIC package and is designed for surface mount applications. Its characteristics make it suitable for use in applications such as high-speed integrators, digital-to-analog converters, and sample-and-hold circuits.
