1 If current limit is programmed less than 75uA, the current limit will be set to 75µA (no error will be generated).
2 Approximate voltage loop bandwidth with no external capacitor.
3 Approximate current limit circuit bandwidth with output shorted.
4 Time from the start of bus communication to final byte returned on bus. Assumes the default of 5 data points 30.4µs apart.
5 With any voltage bandwidth setting, and 30kHz current limit bandwidth setting.
6 With a 20 ohm load resistor and current limit set to +0.5125A, program voltage 0V to ±10V. Measure time for voltage to settle
within 20mV of final value.
7 With 20 ohm load resistor and current limit set to +0.5125A, program voltage from 0V to ±10V.
8 With 20 ohm load resistor and voltage set to 10.25V, program current limit from 0A to 0.5A.
9 With 20 ohm load resistor and voltage set to –10.25V, program current limit from 0A to 0.5A.
10 With 1k load resistor, program current from –0.5mA to +0.5mA. Measure time from –0.4mA to +0.4mA.
