MAX397CAI+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397CAI+ is a precision, dual 8-channel CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It operates with single supplies from +2.7V to +16V or dual supplies from ±2.7V to ±8V. The device features a maximum on-resistance of 100Ω at +25°C and 125Ω across the full temperature range. Key electrical parameters include a channel-to-channel on-resistance matching of 6Ω max, charge injection of 5pC max, and transition times under 250ns. It utilizes a 28-pin SSOP package and supports TTL/CMOS logic inputs.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CAI+' corresponds to the commercial temperature range (0°C to +70°C) and SSOP-28 package configuration required for your design. Confirm RoHS compliance status through official manufacturer documentation prior to finalizing procurement specifications.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when a dual 8-channel configuration is required instead of a single 16-channel unit. Ensure supply voltages remain within the specified operational limits to maintain guaranteed on-resistance flatness and switching speeds. Consider thermal derating if operating near the upper temperature limit.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX396/MAX397 family of low-voltage CMOS analog multiplexers. While the MAX396 provides a single 16-channel path, the MAX397 offers two independent 8-channel paths in the same footprint, facilitating differential signal routing applications without increasing board space requirements.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

Publicly confirmed pin-compatible substitutes include the MAX307, DG407, and DG507A. Verify that these alternatives meet the specific voltage and leakage requirements of the target application before implementation.
