DESCRIPTION

The TSH94 is a quad low power hi gh frequency op-amp, designated for high qua lity vi deo signal processing. The device offers an excellent speed consumption ratio with 4.5mA per amplifier for 150MHz bandwidth.

High slew rate and low noise make it also suitable for high quality audio applications.

The TSH94 offers 2 separate complementary

STANDBY pins :

❑ STANDBY 1 acting on the n° 2 operator ❑ STANDBY 2 acting on the n° 3 operator

They reduce the consumption of the corresponding operator and put the output in a high impedance state.

APPLICATIONS SIGNAL MULTIPLEXING

standby

To put the device in standby, just apply a logic level on the standby MOS input. As ground is a virtual level for the device, threshold voltage has been refered to V

CC

+

at V

+

- 1.6V typ.

CC

In standby m ode, the output goes in hi gh impedance in 200ns. Be aware that all maximum rating must still be followed in this mode. It leads to swing limitation while using the device in signal multiplexing configuration with followers, differential input voltage mu st not exceed ±5V limit ing input swing to 2.5Vpp.
