CA3100
38MHz, Operational Amplifier
Features
• High Open Loop Gain at Video
Frequencies . . . . . . . . . . . . . . . . . . 42dB (Typ) at 1MHz
Description
The CA3100 is a large signal wideband, high speed
operational amplifier which has a unity gain cross over
frequency (f
T
) of approximately 38MHz and an open loop,
3dB corner frequency of approximately 110kHz. It can
operate at a total supply voltage of from 14V to 36V (±7V to
±18V
when using split supplies) and can provide at least
18V
P-P
and 30mA
P-P
at the output when operating from
±15V
supplies. The CA3100 can be compensated with a
single external capacitor and has DC offset adjust terminals
for those applications requiring offset null. (See Figure 1).
The CA3100 circuit contains both bipolar and PMOS transis-
tors on a single monolithic chip.
