MAX398CPE+

Analog Switches, Multiplexers, Demultiplexers Overview

The MAX398CPE+ is a precision, monolithic CMOS analog multiplexer housed in a 16-pin Plastic DIP package. It provides eight bidirectional channels with an on-resistance of less than 100 Ω and a maximum matching tolerance of 6 Ω between channels. The device operates from a single +3V to +15V supply or bipolar ±3V to ±8V supplies. Key electrical characteristics include off-leakage current below 2.5nA at +85°C, charge injection under 5pC, and transition times under 250ns. It features rail-to-rail signal handling and TTL/CMOS logic compatibility.

Analog Switches, Multiplexers, Demultiplexers Procurement Notes

Verify the specific suffix 'CPE+' against the manufacturer's ordering guide to confirm the commercial temperature range (0°C to +70°C) and plastic DIP packaging. Ensure that the component meets RoHS compliance requirements if applicable to the target assembly process. Cross-reference the datasheet revision history to validate the accuracy of the pinout and absolute maximum ratings before final integration.

Analog Switches, Multiplexers, Demultiplexers Selection Notes

Select this component when high channel count and precise resistance matching are required for low-voltage applications. The MAX398CPE+ is suitable for designs needing fast switching speeds and low leakage over a wide temperature range. Consider the exposed pad requirement if utilizing QFN variants, though the CPE+ uses a standard through-hole configuration. Verify power supply sequencing to prevent latch-up during startup conditions.

Analog Switches, Multiplexers, Demultiplexers Part Context

The MAX398CPE+ belongs to the MAX398/MAX399 family of precision analog multiplexers manufactured by Analog Devices Inc./Maxim Integrated. This series is designed for general-purpose signal routing where low distortion and high isolation are critical. The device utilizes a low-voltage silicon-gate process to achieve superior performance metrics compared to older discrete solutions.

Analog Switches, Multiplexers, Demultiplexers Replacement Considerations

The MAX398CPE+ is explicitly documented as being pin-compatible with the DG408, DG409, DG508A, and DG509A. These industry-standard parts can serve as direct replacements in existing designs without requiring PCB layout modifications.
