Use the Motorola MC14007 dual complementary pair plus inverter with two MOSFET amplifiers as differential amplifiers for the buffer op amp and the third as the current source for the differential amplifier. Arrange to give high input impedance. These high input impedances are required for some MC1505 A/D converter applications that are designed to buffer.
