Analog preamplifier EPC1-D

precision

APPLICATIONS • - Measurements of very weak signals, e.g. very low temperatures • - Precision measurements with very high sensitivity • - Measurement of signals from devices with high internal impedance, such as piezoelectric sensors or capacitive sensors Temperature, deformation, pressure, force, acceleration, displacement... DESCRIPTION The EPC1-D preamplifier is characterized primarily by its low noise level, high input impedance and gain accuracy. An original bias circuit allows to obtain a very low cut-off frequency while maintaining good performance in noise level. TECHNICAL FEATURES Very low input noise: e.g. 2nV/√Hz at 1 Hz, 0.7 nV/√Hz at 10KHz - • High impedance direct coupling or AC voltage coupling • Gain up to 10000 • High bandwidth : Fc <0.05 Hz to 130 KHz • Excellent common mode rejection
