The Texas Instruments LF347M/NOPB is a JFET-input quad operational amplifier in a 14-SOIC surface-mount package.
Total quiescent current is 7.2 mA for all four amplifiers. In a 14-SOIC package, self-heating is negligible at room temperature.
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.
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.
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.
Yes, it is ROHS3 compliant, meeting the latest RoHS directive requirements.
