MAX333ACWP

MAX333ACWP Description

The MAX333ACWP from Analog Devices Inc./Maxim Integrated is a high-performance, 4-channel SPDT (Single Pole Double Throw) analog switch designed for precision signal routing in demanding applications. Housed in a 20-pin SOIC package, this IC offers low on-resistance (45Ω max) and minimal leakage current (250pA max), ensuring high signal integrity. It supports dual (±4.5V to ±20V) and single (10V to 30V) supply voltages, making it versatile for mixed-voltage systems. Although marked as obsolete, its robust performance metrics, including fast switching (175ns Ton, 145ns Toff) and low charge injection (2pC), make it a reliable choice for legacy designs.

MAX333ACWP Features

• Low On-Resistance: 45Ω max ensures minimal signal attenuation.
• Low Leakage: 250pA max for high-precision applications.
• Fast Switching: 175ns (Ton), 145ns (Toff) for dynamic signal routing.
• Wide Voltage Range: Supports ±4.5V to ±20V (dual) and 10V to 30V (single) supplies.
• Low Charge Injection: 2pC reduces glitches in sensitive circuits.
• Channel Matching: ΔRon ≤ 2Ω for consistent performance across channels.
• Low Capacitance: 5pF (CS(off), CD(off)) minimizes crosstalk.
• 4-Channel SPDT: Ideal for multiplexing/demultiplexing (2:1 circuit).
