MAX397CAI-T

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX397CAI-T is a precision analog multiplexer switch IC manufactured by Analog Devices Inc. under the Maxim Integrated brand. It features two independent 8-to-1 multiplexer circuits housed in a 28-pin SSOP package. The device supports single supply voltages ranging from 2.7 V to 16 V, or dual supplies of ±2.7 V to ±8 V. Key electrical parameters include a maximum on-resistance of 100 Ohms with a channel-to-channel matching of 1.8 Ohms. Switching times are specified at a maximum of 150 ns for both turn-on and turn-off periods. The component operates within a temperature range of 0°C to +70°C.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'T' indicates tape-and-reel packaging versus the standard tube packaging found in other variants like the MAX397CAI+. Confirm availability status as distributors may list this specific reel variant differently than the standard tube version. Ensure the operating temperature grade matches the application requirements.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when dual independent 8-channel switching is required within a compact SSOP footprint. Compare the 100 Ohm on-resistance against higher-performance alternatives if lower distortion is critical. Verify that the 0°C to +70°C commercial temperature range meets the environmental constraints of the target system.

Analog Switches, Multiplexers, Demultiplexers Part Context

This part belongs to the MAX397 series of precision multiplexer switches. It shares functional similarities with the MAX396 but offers dual 8:1 channels instead of quad 4:1 channels. The series is designed for applications demanding high accuracy and low power consumption in signal conditioning paths.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX397CAI+ serves as a direct pin-compatible alternative, differing primarily in packaging format (tube vs. tape). Verify that the packaging preference aligns with assembly line capabilities before substituting.
