Overview
The MAX14585/MAX14585A, although the specific part number MAX145BCUA does not match this description, it is important to note that the MAX145 series generally refers to high-performance switching devices. The MAX14585/MAX14585A are high-ESD-protected double-pole/double-throw (DPDT) switches designed to multiplex Hi-Speed USB signals and AC-coupled analog signals such as audio or video. These devices are optimized for high-performance switching applications in portable electronics, operating from a 2.7V to 5.5V supply and featuring low on-capacitance and low on-resistance. They also include an internal negative supply to pass audio signals below ground and handle USB low-/full-speed signaling.
However, the MAX145BCUA specifically refers to a different product line, which is part of the MAX144/MAX145 series of low-power, 12-bit analog-to-digital converters (ADCs). These ADCs operate with a single supply from 2.7V to 5.25V and are known for their low power consumption and high-speed serial interface.
