Description
The TSH300 is a voltage feedback amplifier
featuring ultra-low input voltage and current noise.
This feature, associated with a large bandwidth,
large slew rate and a good linearity, makes the
TSH300 a good choice for high-speed data
acquisition systems where sensitivity and signal
integrity are the main priorities.
The TSH300 is a single operator available in SO8
and the tiny SOT23-5L plastic package, saving
board space as well as providing excellent
thermal performances.

1. All voltage values are measured with respect to the ground pin.
2. Differential voltage is between the non-inverting input terminal and the inverting input terminal.
3. The magnitude of input and output voltage must never exceed V
CC
+0.3V.
4. Short-circuits can cause excessive heating. Destructive dissipation can result from short circuits on amplifiers.
5. Human body model, 100pF discharged through a 1.5kΩ resistor into P
min
of device.
6. This is a minimum value. Machine model ESD, a 200pF cap is charged to the specified voltage, then
discharged directly into the IC with no external series resistor (internal resistor < 5Ω), into pin to pin of device.
