MSP430FR2355: Driving LEDs using SAC in buffer mode

Gergo Santha

Part Number: MSP430FR2355

Hi!

Instead of using external transistors can I use 2 SACs in buffer mode to drive a 2 LEDs with ~10mA each? Any tip would be welcome!

Hello,

No, you may not do that. The output load current of OA + DAC is 1mA in high-power mode. It can not drive a 10mA LED.
