OPA698 - Burr-Brown

OPA698 Voltage Limiting Amplifier

The OPA698 is a wideband, unity-gain stable voltagefeedback op amp that offers bipolar output voltage limiting. Two buffered limiting voltages take control of the output when it attempts to drive beyond these limits. This new output limiting architecture holds the limiter offset error to ±10mV. The op amp operates linearly to within 20mV of the output limit .
