1 HA-2640, ha-2645 4mhz, high supply voltage operational amplifiers HA-2640 and ha-2645 are monolithic operational ampli?rs which are designed to deliver unprecedented dynamic speci?ations 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 ampli?rs offer unconditional output overload protection through current limiting and a chip temperature sensing circuit. this sensing device turns the ampli?r ?ff? when the chip reaches a certain temperature level. these ampli?rs 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/ s 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 ampli?rs excitation designs. features output voltage swing . . . . . . . . . . . . . . . . . . . . . . . . 35v supply voltage . . . . . . . . . . . . . . . . . . . . . . 10v to 40v offset current. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5na bandwidth. . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 4mhz slew rate . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 5v/ s common mode input voltage range . . . . . . . . . . . . 35v output overload protection applications industrial control systems power supplies high voltage regulators resolver excitation signal conditioning pinouts ordering information part number temp. range ( o c) package pkg. no. ha2-2640-2 -55 to 125 8 pin metal can t8.c ha2-2645-5 0 to 75 8 pin metal can t8.c ha7-2640-2 -55 to 125 8 ld cerdip f8.3a ha7-2645-5 0 to 75 8 ld cerdip f8.3a HA-2640/2645 (cerdip) top view HA-2640/2645 (metal can) top view bal -in +in v- 1 2 3 4 8 7 6 5 comp v+ out bal - + comp out -in v- bal +in v+ bal 2 4 6 1 3 7 5 8 - + (to-99 case voltage = floating) data sheet september 1998 file number 2904.3 caution: these devices are sensitive to electrostatic discharge; follow proper ic handling procedures. 1-888-intersil or 321-724-7143 | copyright intersil corporation 1999
