OPA454 SBOS391A – DECEMBER 2007 – REVISED DECEMBER 2008 High-Voltage (100V), High-Current (50mA) OPERATIONAL AMPLIFIERS, G = 1 Stable 1FEATURES DESCRIPTION 2• WIDE POWER-SUPPLY RANGE: The OPA454 is a low-cost operational amplifier with ±5V (10V) to ±50V (100V) high voltage (100V) and relatively high current drive • HIGH OUTPUT LOAD DRIVE: IO ±50mA (50mA). It is unity-gain stable and has a • WIDE OUTPUT VOLTAGE SWING: 1V to Rails gain-bandwidth product of 2.5MHz. • INDEPENDENT OUTPUT DISABLE OR The OPA454 is internally protected against SHUTDOWN over-temperature conditions and current overloads. It is fully specified to perform over a wide power-supply • WIDE TEMPERATURE RANGE: –40°C to +85°C range of ±5V to ±50V or on a single supply of 10V to • SO-8 PACKAGE 100V. The status flag is an open-drain output that allows it to be easily referenced to standard APPLICATIONS low-voltage logic circuitry. This high-voltage op amp • TEST EQUIPMENT provides excellent accuracy, wide output swing, and
