The OPAx994 family (OPA994 and OPA2994) is a family of high voltage (32V) rail-to-rail input and output (RRIO) operational amplifiers. These devices offer excellent AC performance, including a wide unity gain bandwidth of 24MHz and a high slew rate of 35V/µs, while only requiring a quiescent current of 1.35mA per channel.
The OPAx994 family was designed to maintain stability across a wide range of capacitive loads. For example, OPAx994 is able to achieve a phase margin of 50 degrees when driving large capacitive loads of 10µF with a load resistance of 1MΩ. The OPAx994 is designed with compensation architectures that mitigate sustained ringing for large capacitive loads. This allows for reliable performance and ease of design for systems that have large, varying, or unknown capacitive loads.
These devices also offer excellent DC precision, including a high short-circuit output current of 125mA/channel, low offset voltage (±350µV, typical), low offset drift (±2.5µV/°C, typical), and high CMRR of 125dB for high voltage operation within the main input pair. This makes the OPAx994 a flexible, robust, and high-performance op amp for high-voltage industrial applications.
