airborne amplifiers for flightEndevco has launched a series of compact, lightweight, rugged airborne amplifiers, designed for use within demanding flight test applications. Operating from an onboard aircraft DC-power source, Endevco airborne amplifiers are designed for use with piezoelectric microphones and accelerometers. The Endevco 2680M-XXX is a charge amplifier, offering dual outputs, one biased and the other, unbiased, both of which are adjustable with a common gain control. Units are available with an optional low-pass filter. Endevco model 2685V is a voltage amplifier for use with ISOTRON (IEPE) accelerometers, providing a constant current power source to a transducer’s integral electronics, while maintaining a two-wire connection. The hybrid microcircuit construction of both the Endevco 2680M-XXX and 2685V series allow them to be offered in a rugged, compact package, with low power consumption. Units have an output voltage proportional to input acceleration or sound. Amplifier sensitivity is not significantly affected by input cable capacitance. Use of modular construction techniques permits versatility in gain and filter choices.
