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.
