A time constant of around 1hz would work. Thanks jim you're a hero :) Now onto the next issue.
Can You Help Me Achieve a 5x DC Gain for Opamp Output Voltage?
Click For Summary
SUMMARY
The forum discussion centers on achieving a 5x DC gain for an op-amp output voltage to reach +/- 150V without resorting to expensive high-voltage op-amps. Users suggest utilizing opto-isolators and voltage dividers to control high voltage at low power levels, emphasizing the need for a proper design architecture. Key components mentioned include the PA340 op-amp for high voltage applications and the use of LTSpice for circuit simulation. The discussion highlights the importance of understanding circuit elements and their configurations to achieve the desired voltage gain.
