SBOU323 June 2025 XTR200
For current mode, use Equation 1 to calculate the output current. The default value for the RSET resistor (R9) is 1.5kΩ, optimized for input voltage ranges of 0V to 3V, to achieve an output signal of 0mA to 20mA.
Table 2-2 shows a list of RSET resistor values for common input voltage ranges and output current ranges.
Input Voltage Range (V) | Output Current Range (mA) | RSET Resistor Value (Ω) |
|---|---|---|
0-1.8 | 0-20 | 900 |
0-25 | 720 | |
0-2.5 | 0-20 | 1.25k |
0-25 | 1k | |
0-3 | 0-20 | 1.5k |
0-25 | 1.2k | |
0-5 | 0-20 | 2.5k |
0-25 | 2k |
