Low-cost high performance JFET input op-amps that will directly replace & out-perform the 741 in most applications. The devices are low noise have distortion figures of less than 0.02 over the audio band high slew rate 13 Vmicros high input impedance 1012 Omega & wide bandwidth. For the 347 internal amplifier isolation is 120d B. in addition the accurately matched JFET inputs provide very low input bias & offset currents. It is most important that input voltages never go more negative than the negative supply voltage or the device will be destroyed. The ICs are ideal for audio circuits as well as fast DA convertors high speed integrators & sample-&-hold circuits. The 351 is supplied in an 8-pin DIL package & the 347 is supplied in a 14-pin DIL package & is a quad version. Note that since the inputs are JFETs not MOSFETs no special handling is required.
