MAX4598CPP

Analog Switches - Special Purpose Overview

The MAX4598CPP is a low-voltage CMOS analog multiplexer manufactured by Analog Devices Inc./Maxim Integrated. It supports single-ended 8-to-1 or differential 4-to-1 configurations. The device operates from a single +2.7V to +12V supply or dual ±6V supplies. Key electrical parameters include a maximum on-resistance of 75Ω, off-leakage current of 0.1nA at +25°C, and charge injection of 2pC typical. It features TTL-compatible logic inputs and handles rail-to-rail analog signals. The component is housed in a 20-pin SSOP package and functions within an operating temperature range of 0°C to +70°C.

• Audio-Signal Routing

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix CPP corresponds to the 20-pin SSOP package and commercial temperature range (0°C to +70°C) before procurement. Confirm that the source document explicitly identifies this part number variant. Ensure compatibility with single-supply or dual-supply requirements as the device supports both ranges. Check for any discontinuance notifications associated with the Maxim Integrated product line.

Analog Switches - Special Purpose Selection Notes

Select the MAX4598CPP when a configurable multiplexer capable of handling rail-to-rail signals is required. Consider its low leakage current and on-resistance flatness for precision applications. Evaluate the need for latchable operation if address stability during power transitions is critical. Verify that the 75Ω maximum on-resistance meets the signal integrity requirements of the target circuit design.

Analog Switches - Special Purpose Part Context

The MAX4598 belongs to the Maxim Integrated low-voltage CMOS analog switch family. It is designed for versatile signal routing in mixed-signal systems. The device integrates ESD protection exceeding 2kV per Method 3015.7. It is distinct from higher-voltage or multi-channel variants within the broader switch IC portfolio.
