With the user’s external resistor “Rin” placed between “G” and “H”, this universal FAST isolated programmable bipolar amplifier (three-terminal isolation) eases the processing of all signals “Vin” between “± 50mV” and “± 500V”. Enabling amplification or attenuation, it transforms “Vin” = 0 to ¦maxi¦ into a standardized “Vout” signal “0 to ± 10V”.
Gain “Vout / Vin” programmed by “Rin” resistance:
The value of “Rin” linearly depends on the maximum value of the “Vin” voltage applied on the amplifier; Rin = (20kΩ x “Vin max”) – 1 kΩ
Example: if Vin max = 5V, then Rin = (20kΩ x 5) – 1kΩ = 99kΩ
Input:
- Input voltage: range “0 to ± 50mV” upto range “0 to ± 500V”
- Input current: limited to 50µA (with Rin adjusted to Vin)
- Precision of the ratio “20kΩ / volt”: < 2.10-3
Output:
- Output voltage: 0 to ± 10V (standardized)
- Output current: 0 to ± 10mA
- Whatever “Vout”: < ±10V if the gain is reduced
- Gain dynamics: 10 000
- Gain linearity: < 10-4
- Response time: 250µs, Vout varying from 0 to ±10V
- Isolated (2.5kV) from the input and the power supply
- Ripple: < 50mV / ≈ 35kHz
Protections:
- Three-terminal isolation: 2.5kV
- Overloads on the input: +100% of “Vin” max
