MRC APPLICATIONS:
The MRC1/2 will dissipate 1/2 watt at 70°C on a 1206 footprint, while the MRC 1 will dissipate 1 watt at 70°C on a 2010
footprint. The MRC is recommended for applications where board real estate is a major concern. Due to the high power
density and superior surge handling capability, it is also recommended as a direct replacement on existing board
designs where standard 1206 or 2010 resistors are marginal or failing.

What are the commonly used 4-to-1 analog switch chips?
I need a 4-to-1 analog switch. The ADG series analog switches of ADI are all 2-to-1. Can you provide a good 4-to-1 analog switch with a power supply voltage of 3.3 volts? Thanks in advance....
