  Output short-circuit (5)  
1. All voltage values, except differential voltage, are with respect to network terminal.
2. Charged device model: all pins and the package are charged together to the specified voltage and then
discharged directly to the ground through only one pin. This is done for all pins.
3. Human body model: a 100 pF capacitor is charged to the specified voltage, then discharged through a
1.5 k resistor between two pins of the device. This is done for all couples of connected pin combinations
while the other pins are floating.
4. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between
two pins of the device with no external series resistor (internal resistor < 5 ). This is done for all couples of
connected pin combinations while the other pins are floating
5. An output current limitation protects the circuit from transient currents. Short-circuits can cause excessive
heating. Destructive dissipation can result from short-circuits on amplifiers.


Description

The TSH122 is a video buffer that uses a voltage feedback amplifier, with an internal gain of 6 dB, an output rail-to-rail, an internal input DC-shift and a SAG correction. A power-down function allows switching to a sleep mode with an ultra-low consumption.

The TSH122 features a 6th-order internal reconstruction filter to attenuate the parasitic frequency of 27 MHz from the clock of the video DAC.

The TSH122 operates from 2.25 to 5 V single power supplies and is tested at 2.5 V and 3.3 V.

The TSH122 is a single operator available in a tiny SC70 plastic package for space saving.
