NXP Semiconductors BCY87
The BCY87 and BCY88 are intended for use in pre-stages of differential amplifiers where low offset, low drift and low noise are of prime importance • The BCY89 is intended for use in second stages of differential amplifiers, long-tailed pairs and more general applications.FEATURES
● Low current (max. 30 mA)● Low voltage (max. 45 V).
APPLICATIONS
● Differential amplifier applications in general industrial service e.g. instrumentation and control●
