It is useful in a wide variety of applications requiring high output voltage or large common-mode voltage swings. The OPA445’s high slew rate provides wide power- bandwidth response, which is often required for high-voltage applications. FET input circuitry allows the use of high-impedance feedback networks, thus minimiz- ing their output loading effects. Laser trimming of the input circuitry yields low input offset voltage and drift. The OPA445 is available in standard pinout TO-99, DIP-8, and SO-8 surface-mount packages as well as an SO-8 PowerPAD package for reducing junction temperature. It is fully specified from −25 °C to +85°C and operates from −55 °C to +125°C. A SPICE macromodel is available for design analysis (from www.ti.com). 8 1 2 7 6 5 3 4 Offset Trim Offset Trim Output V+ NC −In +In V − Case is connected to V − TO−99 OPA445 1 2 3 45 6 7 8 Offset Trim V+ −In +In V − Output Offset Trim NC DIP−8, SO−8, SO−8 PowerPAD OPA445 NC = No internal connection; leave NC floating or connect to GND, V+, or V−.
