DESCRIPTION
The TSH8x serie offers Single and Dual opera-
tional amplifiers featuring high video performanc-
es with large bandwidth, low distortion and excel-
lent supply voltage rejection. These amplifiers fea-
ture also large output voltage swing and high out-
put current capability to drive standard 150
loads.
Running at single or dual supply voltage from 4.5V
to 12V, these amplifiers are tested at 5V(±2.5V)
and 10V(±5V) supplies.
The TSH81 also features a Standby mode, which
allows the operational amplifier to be put into a
standby mode with low power consumption and
high output impedance.The function allows power
saving or signals switching/multiplexing for high
speed applications and video applications.
For board space and weight saving, TSH8x series
is proposed in SOT23-5, TSSOP8 and SO8 pack-
ages.
