4MHz, High Supply Voltage Operational
Amplifiers

HA-2640 and HA-2645 are monolithic operational amplifiers
which are designed to deliver unprecedented dynamic
specifications for a high voltage internally compensated
device. These dielectrically isolated devices offer very low
valuesfor offset voltage and offsetcurrent coupled with large
output voltage swing and common mode input voltage.

For maximum reliability, these amplifiers offer unconditional
output overload protection through current limitingand a chip
temperature sensing circuit. This sensing device turns the
amplifier “off”, when the chip reaches a certain temperature
level.

These amplifiers deliver ±35V common mode input voltage
range, ±35V output voltage swing, and up to ±40V supply
range for use in such designs as regulators, power supplies,
and industrial control systems. 4MHz gain bandwidth and
5V/µs slew rate make these devices excellent components
for high performance signal conditioning applications.
Outstanding input and output voltage swings coupled with a
low 5nA offset current make these amplifiers excitation
designs.
