On the other hand the common mode input voltage has to be maintained below (VDD-1.2V) to keep the input device (M2 and M3) active. This implies that when using HT9291/HT9292/HT9294 as a voltage follower, the input as well as output active range will be limited between VSS~VDD-1V (approx.). Avoid applying any voltage greater than VDD+0.6V or less than VSS-0.6V to the input pins, otherwise the internal input protection devices may be damaged. V V M1 N o n in v e r tin g In In v e r tin g In M2 PMOS M3 PMOS DD Output Stage The HT9291/HT9292/HT9294 uses push-pull CMOS configuration as the output stage of op amps to minimize low power consumption and to provide adequate output driving current. Note that the output is an unbuffered structure, therefore the open loop gain will be affected by the load resistor since the voltage gain of this stage can be expressed as (gm5+ gm6)RL. V DD V B IA S B IA S M5 OUT F ro m D iffe r e n tia l Amp M6 V T o O u tp u t S ta g e SS V M4 SS M5 V SS Since the input impedance of PMOS is inherently very high, it can directly couple to high impedance elements without loading effect. For example, coupling to ceramic transducers, integrating capacitor and resistor networks. Actually the extremly high input impedance is its major advantage over the bipolar counterpart, in some application fields such as integrators where the input current of op amp can cause significant error. Because of the consideration for minimized power consumption, the output short circuit current is limited to about -1.2mA for source drive and 4mA for sink drive. This is believed to be enough for most low power systems, however it is recommended to use the load resistor of >1MW for normal applications. In case of heavy load driving, an external buffer stage using bipolar transistors is recommended. The HT9291/HT9292/HT9294 is internally compensated for AC stability and capable to withstand up to a 60pF capacitive load.
