DESCRIPTION
TheTSH22 is a dual bipolar operational amplifier
offering a single supply operation from 3V to 30V
with very good performances : medium speed
(25MHz), unity gain stability and low noise.
The TSH22 is therefore an enhanced replacement
of standard dual operational amplifiers.

APPLICATIONS INFORMATION
TSH22 IN COMPARATOR APPLICATION
The TSH22 is a dual high performances opera-
tional amplifier featuring speed of 30MHz and sin-
gle supply operation from 3V to 30V.
Most of operational amplifiers are not suited for
comparator use because of low transition speed,
output signal incompatible with standard logics
level and mainly, phase inversion.
The phase inversion occures when a strong differ-
ential signal is applied to the device inputs. The
output level is then inverted and shows a wrong
logic state. TSH22 does not present this problem-
atic behaviour.
Figure 1 :
Basic comparator application
Displayed curves below show the device re-
sponse in standard comparator configuration with-
out external components.
Transition speed : Typical transition speed under
a single 5V supply voltage is about 2µs from
50mV overdrive. V
OH
min. is 3.7V and V
OL
max. is
0.2V (2kΩ load) making it compatible with stan-
dard logic families.
Figures 3 & 4 show output signal transition for a
50mV and 250mV input signal overdrive respec-
tively of 3µs and 1µs.
