MAX4992EVB+T

The MAX4991–MAX4994 low 0.3Ω (typ) on-resistance analog switches have break-before-make switching and operate from a single +1.8V to +5.5V supply. The MAX4991/MAX4993 provide a slow turn-on time, and with COM_ used as the output, reduce clicks and pops due to coupling capacitors and audio amplifiers with a DC output bias.

Applications

• Speaker Headset Source Switching
• Cellular Phones
• Portable MP3 Players
• Audio Signal Routing

Key features

• The MAX4991–MAX4994 low on-resistance analog switches operate from a single +1.8V to +5.5V supply.
• The MAX4991/MAX4993 feature a slow turn-on time to reduce clicks and pops due to coupling capacitors and audio amplifiers with a DC output bias. This feature provides click-and-pop reduction without adding additional parts for existing architectures.
• The MAX4991/MAX4992 are dual single-pole/double-throw (SPDT) switches, while the MAX4993/MAX4994 are double-pole/double-throw (DPDT) switches.
• The MAX4993/MAX4994 feature an active-low enable input (EN) that sets all the channels to high impedance and reduces supply current when driven high.
• These devices have 0.3Ω on-resistance and 0.004% THD+N to route high fidelity audio signals.
• The MAX4991–MAX4994 are available in space-saving 10-pin UTQFN (1.4mm×1.8mm) package, and are specified for operation over the -40°C to +85°C extended temperature range.
