The CA5470 is an operational amplifier that combines the
advantages of both high speed CMOS and bipolar transistors
on a single monolithic chip. It is constructed in the BiMOS-E
process which adds drain-extension implants to 3µm polygate
CMOS, enhancing both the voltage capability and providing
vertical bipolar transistors for broadband analog/digital func-
tions. This process lends itself easily to high speed operational
amplifiers, comparators, analog switches and interface periph-
erals, resulting in twice the speed of the conventional CMOS
transistors having similar feature size.
BiMOS-E are broadbased bipolar transistors that have high
transconductance, gains more constant with current level, sta-
ble “precision” base-emitter offset voltages and superior drive
capability. Excellent interface with environmental potentials
enable use in 5V logic systems and future 3.3V logic systems.
Refer to Application Note AN8811.
ESD capability exceeds the standard 2000V level. The
CA5470 series can operate with single supply voltages from
3V to 16V or ±1.5V to ±8V. They have guaranteed specifica-
tions at both 5V and ±7.5V at room temperature as well as
over the full -55^oC to 125^oC military range.
