TSH300
Ultra Low-Noise High-Speed Operational Amplifier
Structure: VFA
200 MHz bandwidth
Input noise: 0.65 nV/Hz
Stable for gains > 5
Slew rate: 230 V/µs
Specified on 100 load
Tested on 5 V power supply
Single or dual supply operation
Minimum and maximum limits are tested in full
production
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.
