High Current/High Voltage OPAMP with Boost Output Current Greater Than 1A, OPA454
This project provides High Voltage and High Current output swing. The board is built using OPA454 OPAMP and 2 x high current NPN/PNP BJT Transistors. Output transistors Q1 and Q2 provide positive and negative output currents to the load. The project works with an input power supply up to +/-50V DC. OPAMP Vout swings from +47V to -48V and OP output swings from +44.1V to -45.1V at 1A. Connect the J1 jumper to GND (EC Middle Pin + GND Pin) to Enable the output.
The output can be independently disabled using the Enable or Disable Pin that has its common return pin to allow easy interface to low-voltage logic circuitry. This disable is accomplished without disturbing the input signal path, not only saving power but also protecting the load.
Test is conducted with Dual +/- 25Vdc Power Source, Load 10/5W Ohms Resistor, Input +/-1V, Output +/-1A Dual 23V DC (Approx.)
Features
- Power Supply +/-50V DC (Range +/-5V to +/-50V DC)
- Output Current Swings 1Amp
- Output swings from +44.1 V to –45.1 V at IL = 1 A (Supply Dual 50V)
- Input +/-1V
- Independent Output Disable or Shutdown
- 4x4mm Mounting Holes
- PCB Dimensions 76.20 x 29.37 mm
Applications
- Servo Drivers
- Test Equipment
- Transducer Drivers
- High-Voltage Compliance Current Sources
- General High-Voltage Regulators and Power
The OPA454 device is a low-cost operational amplifier with high voltage (100 V) and relatively high current drive (50 mA). The OPA454 device is a low-cost operational amplifier with high voltage (100 V) and relatively high current drive (50 mA). It is unity-gain stable and has a gain-bandwidth product of 2.5 MHz
The OPA454 is internally protected against overtemperature conditions and current overloads. It is fully specified to perform over a wide power-supply range of ±5 V to ±50 V or on a single supply of 10 V to 100 V. The status flag is an open-drain output that allows it to be easily referenced to standard low-voltage logic circuitry. This high-voltage operational amplifier provides excellent accuracy, wide output swing, and is free from phase inversion problems that are often found in similar amplifiers.
