Product details

What this quad JFET op-amp delivers

The Texas Instruments LF347M/NOPB is a JFET-input quad operational amplifier in a 14-SOIC surface-mount package. It provides four independent op-amp circuits with a 4 MHz gain-bandwidth product and a 13 V/µs slew rate, drawing 7.2 mA total supply current across all four channels.

Slew rate and bandwidth — what they mean for your signal chain

The 13 V/µs slew rate and 4 MHz gain-bandwidth product support audio-band signals and industrial sensor-conditioning paths.

Supply current and thermal budget

Total quiescent current is 7.2 mA for all four amplifiers. In a 14-SOIC package, self-heating is negligible at room temperature.

Frequently asked questions

What is the exact pinout of LF347M/NOPB?

The LF347M/NOPB uses the standard 14-SOIC quad op-amp pinout: output 1 (pin 1), inverting input 1 (pin 2), non-inverting input 1 (pin 3), V+ (pin 4), non-inverting input 2 (pin 5), inverting input 2 (pin 6), output 2 (pin 7), output 3 (pin 8), inverting input 3 (pin 9), non-inverting input 3 (pin 10), V- (pin 11), non-inverting input 4 (pin 12), inverting input 4 (pin 13), output 4 (pin 14). This matches the industry-standard quad op-amp footprint.

Is LF347M/NOPB equivalent to LF347N?

The LF347M/NOPB is the surface-mount 14-SOIC variant of the LF347 quad JFET op-amp family. The LF347N is the through-hole DIP-14 version. Electrically they are identical — same 4 MHz GBW, 13 V/µs slew rate, and 50 pA input bias. The only difference is the package and mounting method.

Can LF347M/NOPB operate from a single 5V supply?

No, the minimum supply voltage is 10 V total, so a single 5 V rail is below the operating range. It can run from a single 10 V to 36 V supply, or from dual ±5 V to ±18 V rails.

Is LF347M/NOPB RoHS compliant?

Yes, it is ROHS3 compliant, meeting the latest RoHS directive requirements.
