The LEDX pin can be used as the source of timing for an external LED driver circuit, as in the longer range add-on evaluation board, ADUX1020-EVALZ-LED. In this circuit, the LEDX pin is protected from the large peak currents through the LED by two MOSFETs. Any external LED drive circuit may be designed to work with the ADUX1020, so long as it has enough bandwidth to support 3 μsec LED pulses and protect the LEDX pin from voltages greater than 3.6 V. See the ADUX1020-EVALZ-LED product page for more details.
Hello Tylerray;
On datasheet; it says proximity sensing to 20 cm. Can ADUX1020 support a longer range like 50cm? If yes; how to achieve it?
Thanks;
Bell
