General Description
The Holtek HT9231/HT9232/HT9234 range of
Operational Amplifiers operate with a single supply
voltage as low as 2.0V and offer a low supply current of
only 220mA/amplifier. In offering rail-to-rail output
voltage the devices can operate with a maximum
voltage range. The devices also provide a gain
bandwidth product of 2.3MHz and are also unity gain
stable. These products are suitable for a wide range of
analog signal processing applications but especially
suitable for the portable device and battery powered
equipment application areas.

HT9231/HT9232/HT9234
Functional Description
Input stage
Output stage
The input stage of op amps are nominal PMOS differen-
tial amplifiers (see the following diagram), therefore the
common mode input voltage can extend to VSS-0.6V.
On the other hand the common mode input voltage has
to be maintained below (VDD-1.4)V to keep the input de-
vice (M2 and M3) active. This implies that when using
HT9231/HT9232/HT9234 as a voltage follower, the in-
put as well as output active range will be limited be-
tween 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 de-
vices may be damaged.
The HT9231/HT9232/HT9234 uses push-pull CMOS
configuration as the output stage of op amps to mini-
mize 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.

Because of the consideration for minimized power con-
sumption, output short circuit current is limited to about
-9mA for source drive and 9.5mA for sink drive. This is
believed to be enough for most low power systems,
however it is recommended to use the load resistor of
>10kW for normal applications. In case of heavy load
driving, an external buffer stage using bipolar transistors
is recommended.

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 net-
works.
The HT9231/HT9232/HT9234 is internally compen-
sated for AC stability and capable to withstand up to a
60pF capacitive load.
Actually the extremly high input impedance is its major
advantage over the bipolar counterpart, in some appli-
cation fields such as integrators where the input current
of op amp can cause significant error.
