MAX7391CMTP

Clock Generators, PLLs, Frequency Synthesizers Overview

The MAX7391CMTP is a high-speed, low-power quad analog switch manufactured by Analog Devices Inc./Maxim Integrated. It integrates four single-pole double-throw (SPDT) switches within a compact TDFN package. The device supports dual supply voltages ranging from ±2.7V to ±5.5V or a single supply of 5.5V. Key electrical characteristics include a maximum on-resistance of 4Ω and a channel-to-channel matching of 0.05Ω. It features fast switching times with a maximum ton of 60ns and toff of 80ns, alongside low charge injection of 0.5pC. The component operates within a temperature range of -40°C to +85°C.

Clock Generators, PLLs, Frequency Synthesizers Feature Summary

Clock Generators, PLLs, Frequency Synthesizers Part Context

The MAX7391 belongs to the MAX739x family of high-speed analog switches. The 'CM' suffix indicates the commercial temperature range (-40°C to +85°C), while 'TP' denotes the specific TDFN-16 package variant. This part is distinct from the ADI DACs also bearing the '7391' designation in other product lines.

Clock Generators, PLLs, Frequency Synthesizers Replacement Considerations

Direct replacements within the same family include the MAX7390 (single SPDT), MAX7392 (dual SPDT), and MAX7393 (quad SPST). Cross-manufacturer equivalents should be verified for pin compatibility and on-resistance specifications.
