The 1:8 input-to-output ratio means one SPI command updates all eight channels simultaneously, useful for latching multiple relays in a single bus transaction. Housed in a 20-TSSOP with an exposed pad (20-TSSOP-EP), the part sits on a standard 0.65 mm pitch footprint and the pad pulls heat into the PCB copper pour.","metaTitle":"MAX4820EUP+T Analog Devices Relay Driver, SPI, 8-Ch","metaDescription":"MAX4820EUP+T relay/solenoid driver IC from Analog Devices. 8 low-side outputs, SPI interface, 2 Ohm Rds(on), 70mA per channel.
