■ VERY LOW INPUT CURRENT : 2pA typ
■ GAIN BANDWIDTH PRODUCT : 280MHz
■ GAIN OF 2 STABILI TY
■ SLEW RATE : 300V/µs
■ STANDARD PIN OUT
DESCRIPTION
The TSH31 is a low cos t wide bandwidth single
operational amplifier featuring extremely low input
current of 2pA typ.
Other features as high slew rate, fast settling time
and high linearity make it suit able for many ap plications requiring speed and very high input impedance as photo cell amplifier, F et probe, high
speed precision integrator, sample and hold circuit.
