The MAX4598 is a low-voltage, CMOS analog IC that can be configured as a single-ended 8:1 or differential 4:1 multiplexer. It has low on-resistance (up to 75Ω max) and TTL-compatible logic inputs, capable of handling rail-to-rail analog signals. The MAX4598 has two operating modes: standard multiplexer and latchable multiplexer. It features low off-leakage current and ESD protection. Suitable for applications such as ADC systems, battery-operated equipment, test equipment, avionics, audio-signal routing, and networking.
The MAX4598 is a CMOS analog IC that can be configured as a single‑ended 8‑to‑1 or differential 4‑to‑1 multiplexer. It supports both single‑supply (+2.7 V to +12 V) and dual‑supply (±2.7 V to ±6 V) operation, and allows V+ and GND to be switched to the output channels for power‑monitoring applications. Two operation modes are provided: a standard multiplexing mode and a latchable mode where address lines are strobed.
Key electrical characteristics include a maximum on‑resistance of 75 Ω, off‑leakage currents as low as 0.1 nA at 25 °C, and ESD protection exceeding 2 kV. The device is offered in 20‑pin SSOP, SO, and DIP packages and is suited for ADC systems, battery‑operated equipment, test equipment, avionics, and audio‑signal routing.
