Current modulation
The DRV200 can be modulated from DC to 6 MHz using the SMA connector. The MOD GAIN jumper is used to select
between 3 modulation gains:
DRV200-A-40
Low: 200 µA/V
Medium: 2 mA/V
High: 20 mA/V
DRV200-A-200
Low : 1 mA/V
Medium: 10 mA/V
High: 100 mA/V
DRV200-A-400
Low : 2 mA/V
Medium: 20 mA/V
High: 200 mA/V
Modulation range is ±1 V and input impedance is 50
Ω
.
Supply voltage selection
Set the VCC jumper according to the voltage supply used (5V or 6V). Using a 6V supply provides 1 V of extra
compliance voltage.
Current limit selection
The ILIM jumper can be used to switch between two current limit values:
DRV200-A-40
Low: 32 mA
High: 48 mA
DRV200-A-200
Low: 160 mA
High: 240 mA
