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 operat ional amplifiers.

APPLICATIONS INFORMATION

TSH22 IN COMPARATOR APPL ICATION

The TSH22 is a dual high performances opera-

tional amplifier featuring speed of 30MHz and sin-

gle supply operat ion 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 prese nt this problem-

atic behavio ur.

Fi gure 1 : B asic c om parato r application

Fi gure 3 : Transition speed@ 50mV overdrive

Displayed curves below show the device re-

sponse in standard comparator configuration with-

out extern al compo nents.

Transition speed : Typical transition speed under

a single 5V supply voltage is about 2µs from

50mV overdrive. VOH min. is 3.7V and VOL 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.

PHASE INVERSION

At high differential input voltage, the TSH22 keeps

the right output level thanks to its specific input

structures.

The ad va ntage is obv ious o n the fo llowing figures

and ca n b e also an advantage in linear use when

saturation m ight occure.
