DESCRIPTION:

The TSH321is a widebandmonolithic operational
amplifier, requiringa minimum close loopgain of 2
for stability.

The TSH321featuresextremelyhigh input imped­ance (typically greater than 10

12

Ω) allowing direct

interfacingwith high impedance sources.
Low distortion, wide bandwidth and high linearity

make this amplifiersuitableforRF and video appli­cations. Short circuit protection is provided by an
internal current-limiting circuit.

The TSH321 has internal electrostatic discharge
(ESD)protection circuits andfulfillsMILSTD883C­Class2.
