PRODUCTION DATA.
The maximum current per channel, IOLCmax, is determined by resistor RIREF, placed between the IREF and GND pins. The voltage on IREF is typically 0.8 V. RIREF can be calculated by Equation 1.
where
RIREF must be between 1.02 kΩ and 10.7 kΩ in order to hold the channel sink current IOLC between 25 mA (typical) and 0.3 mA (typical). Otherwise, the output may be unstable.
IOLCmax (mA) | RIREF (kΩ, typical) |
---|---|
25 | 1.02 |
20 | 1.28 |
15 | 1.71 |
10 | 2.56 |
5 | 5.12 |
2.4 | 10.7 |
