Model PH300 is a high performance, thin film hybrid, peak-hold unit, designed to track and hold the peak of analog input signals with rise times (10% to 90% of Vmax) as short as 250 ns. The unit also has the lowest Droop Rate of the held voltage available and consumes less than 36 mW of power in quiescent mode. While this unit was designed for use in satellite instrumentation, the following unique characteristics make it equally useful in a broad range of space, laboratory and commercial applications.
