Pot4 power supply
From DIDEAS Wiki
- +12V, GND, -12V required.
- Absolute maximum supply voltage is +-15V
- Supply current (DC input, no load) < 50mA (35mA typical)
- Due to the outputs driving 1uF capacitive loads, there is an additional AC supply current
- Position output load current : I = (1uF) * 2*pi*f*Vo*sqrt(2)/2 or 4.4e-6 * f * Vo - thus a 100Hz 10V sine wave adds 4.4mA to the position output
- Differential output load current : Vout = ~1e-6 * dVi/dT so I = (1e-6)*(2*pi*Vo)^2 * 1e-3 * sqrt(2)/2 or 2.8e-8 * (f*Vo)^2
- a 50Hz, 10 Hz input has 2.2mA load from the position output, and 7mA on the velocity output
- a 100Hz, 10 Hz input has 4.4mA load from the position output, and 28mA on the velocity output
