SCPS267B March 2017 – February 2020 TCA9803
The TCA980x family has 4 different variants, with different strengths of the internal current source as shown in Table 5.
|Part Number||ICS: Current Source Value|
It is acceptable to select the TCA9803 as the default, since it is able to drive 400-pF bus capacitance loads at 400 kHz. For system designers looking to optimize selection, see the Detailed Design Procedure section for single device for detailed examples of how to select a part number for a specific application.
