NTE824
Integrated Circuit
Low Noise Dual Preamplifier
Description:
The NTE824 is a dual preamplifier for the amplification of low level signals in applications requiring
optimum noise performance. Each of the two amplifiers is completely independent, with an internal
power supply decoupler–regulator, providing 110dB supply rejection and 60dB channel separation.
Other outstanding features include high gain (104dB), large output voltage swing (V
CC
–2V)p–p, and
wide power bandwidth (75kHz, 20V
p–p
). The device operates from a single supply across the wide
range of 9V to 30V.
The amplifiers are internally compensated for gains greater than 10.
