HA-2640, HA-2645 Data Sheet September 1998 File Number 2904.3 4MHz, High Supply Voltage Operational Amplifiers Features 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. • Supply Voltage . . . . . . . . . . . . . . . . . . . . . . ±10V to ±40V 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. • Output Voltage Swing . . . . . . . . . . . . . . . . . . . . . . . . ±35V • Offset Current. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5nA • Bandwidth. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4MHz • Slew Rate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5V/µs • Common Mode Input Voltage Range . . . . . . . . . . . . ±35V • Output Overload Protection Applications • Industrial Control Systems • Power Supplies • High Voltage Regulators • Resolver Excitation • Signal Conditioning Ordering Information TEMP.
