BUF16821: Output channel in parallel configuration to increase output current

Takahiro Saito

Part Number: BUF16821

Hi team,

The datasheet says the maximum output current is 30mA. If customer wants to output more than 30mA, is it okay to use 2ch in parallel to increase the output current? In below case, can the OUT1/OUT2 in parallel configuration output 60mA?

Hi Saito,

I think two channels with same gamma reference outputs are allowed to be paralleled. But I'll do some bench test on our EVM first to confirm this.
