HA-2640, HA-2645

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

values for offset voltage and offset current coupled with

large output voltage swing and common mode input voltage.

For maximum reliability, these amplifiers offer unconditional

output overload protection through current limiting and 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.
