MAX4598CWP+

Analog Switches - Special Purpose Overview

The MAX4598CWP+ is a low-voltage CMOS analog multiplexer available in a 20-pin Wide SO package. It supports single-ended 8-to-1 or differential 4-to-1 configurations, allowing V+ and GND to be switched to outputs for supply monitoring. Operating from a single +2.7V to +12V supply or dual ±6V supplies, it features a maximum on-resistance of 75Ω and TTL-compatible logic inputs. The device offers latched or unlatched operation with an off-leakage current of 0.1nA at +25°C and ESD protection exceeding 2kV per Method 3015.7.

Analog Switches - Special Purpose Feature Summary

• Configurable as single-ended 8-to-1 or differential 4-to-1 multiplexer
• Supports switching V+ and GND to output channels for supply monitoring
• TTL-compatible logic inputs compatible with ±5V or single +5V supplies
• Handles Rail-to-Rail analog signals with low charge injection

Analog Switches - Special Purpose Applications

• ADC Systems
• Battery-Operated Equipment
• Test Equipment
• Avionics
• Audio-Signal Routing

Analog Switches - Special Purpose Procurement Notes

Verify the specific suffix 'C' indicates the commercial temperature range (0°C to +70°C) and 'WP' denotes the 20-pin Wide SO package. Confirm RoHS compliance status through official manufacturer documentation, as legacy Maxim products may have varying environmental declarations. Ensure the ordering code matches the required package style and temperature grade before procurement.

Analog Switches - Special Purpose Selection Notes

Select the MAX4598CWP+ when a combination of single-ended and differential channel routing is required within a single component. The device is suitable for applications needing to monitor supply voltages via switched V+ and GND outputs. Consider the 75Ω maximum on-resistance and 2pC typical charge injection when evaluating signal integrity requirements for precision analog paths.

Analog Switches - Special Purpose Part Context

The MAX4598 belongs to the Maxim Integrated low-voltage CMOS analog switch family. It provides flexible multiplexing capabilities by combining standard switching with addressable power rail monitoring. The C-grade variant specifies operation within the commercial temperature range, distinguishing it from the E-grade extended temperature version.
