Description
The TSH95 is a low-power, high-frequency quad
operational amplifier designated for high-quality
video processing. The device offers an excellent
speed consumption ratio with 4.5 mA per
amplifier for a 150 MHz bandwidth.
A high slew rate and low noise also make it
suitable for high-quality audio applications.
The TSH95 offers two separate complementary
STANDBY pins: STANDBY 1 acting on operators
1 and 2, and STANDBY 2 acting on operators 3
and 4.
These pins reduce the consumption of the
corresponding operators and put the output in a
high impedance state.
