R&F 3HP

Dual slew limiter with independent rise and fall

Buy Assembled » Buy PCBs »

R&F is a dual slew limiter with a way of independently controlling the rise and fall of both channels.

Each slew limiter can have a slew speed from a very short one to a very long one. Since the curve of the slew limiting is linear, a larger jump in value will result in a longer slew period. The following slew times were measured when going from 0V to 5V and back:

  • Slowest rise from 0V to 5V: ~7s

  • Slowest fall from 5V to 0V: ~5s

  • Fastest rise from 0V to 5V: ~4.6ms

  • Fastest fall from 5V to 0V: ~2.7ms

The outputs have circuitry which mitigate voltage drop issues, allowing it to be used for slewing 1V/OCT signals as well. Additionally, both channels have a bipolar LED to monitor the output.
