QMV834BF5 Datasheet The complete schematic is shown after the Electrical Specifications Table. The differential pair Q3 and Q4 form a voltage to current converter whose output is compressed in collector diodes Ql and Q2. These diodes drive the balanced cross-coupled differential amplifier Q7/Q8 Q14/Q15. The gain of these amplifiers is modulated by the voltage to current converter Q9 and Qi0. Transistors Qs, Q6, Q11, and Q12 are constant current sources which bias the voltage to current converter. The output amplifier comprises transistors Q16 through Q27. QMV834BF5 Price
