 The Endevco Model 2680M12-XXX Series Charge Amplifier
is designed for use with piezoelectric transducers and
is suitable for airborne applications. Hybrid microcircuit
construction results in small size, ruggedness and low
power consumption. The unit is a charge amplifier; that
is, it has an output voltage proportional to the charge
at the input. As a result, the amplifier sensitivity is
not appreciably affected by the capacitance of the input
cable.
This unit has two outputs, a biased low gain output with
a gain range of 1 - 10 mV/pC, and a biased high gain output
with a gain range of 10 - 100 mV/PC Both outputs are adjustable
with a common gain control.
The -XXX describes the upper cutoff frequency (-5% point).
For example, a -101 has a low pass filter which is flat
up to 100 Hz, a -502 has a low pass filter which is flat
up to 5000 Hz.
Features:
• For use with piezoelectric transducers
• Small, rugged, light weight
• Dual biased outputs
• Adjustable gain
• Optional low pass filter
