sPDA
2-channel Peripheral Differential Amplifier
The sPDA is a 2 channel version of the Peripheral Differential Amplifier (PDA). It has 2 analog inputs for simultaneous recording of differential bipolar high-ohmic external voltages, such as reference or pH meters. The sPDA is integrated in a cable that connects directly to the peripheral port. The cable ends in 4 bananas (4mm) and is designed for use with the Vertex/sModule (only if a peripheral port is available).
Technical specifications:
- Each cable facilitates recording of up to 2 differential channels
- Cable length 1.3m; 1 black/red banana pair for each channel
- Differential measurement range: ±10 V
- Maximum common mode voltage: ±12 V
- Input impedance: > 10^12 Ohm
