EL5236, EL5237
Features
The EL5236 is a dual, low noise, 300MHz Gain Bandwidth
product Voltage Feedback Op Amp (VFA). The minimum operating
gain of 2 comes with a very low input noise voltage of 1.5nV/ Hz
and 1.8pA/Hz current noise. This makes this dual device ideal
for low noise differential active filters, dual channel photodiode
detectors, differential receivers with equalization, and any other
wideband, high dynamic range application.
Each channel requires only 5.8mA on a ±6V supply. Minimal
performance change over a supply range of ±2.5V to ±6V is
provided (or single +5V ->+12V). Where system power is
paramount, the EL5237 dual with disable allows the amplifiers
to be separately powered down to less than 20µA/Ch.
The 8 Ld dual EL5236 is available in the industry standard
pinout SO-8 or space saving MSOP-8. The 10 Ld EL5237 is
available in an MSOP-10.
