 The Endevco Model 2680M14-XXX Series Charge Amplifier
is designed for use with piezoelectric transducers and
is suitable for airborne applications. Hybrid micro-circuits
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, an unbiased, low gain output
with a gain range of 1 - 10 mV/pC, and an unbiased 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 unbiased outputs
• Adjustable gain
• Optional low pass filter
