MAX333AEPP

MAX333AEPP Description

The MAX333AEPP from Analog Devices Inc./Maxim Integrated is a high-performance, quad SPDT (Single Pole Double Throw) analog switch designed for precision signal routing in demanding applications. Housed in a 20-pin DIP (Through Hole) package, this IC features low on-resistance (45Ω max) and minimal channel-to-channel matching (ΔRon ≤ 2Ω), ensuring consistent signal integrity across multiple channels. With a wide dual supply range (±4.5V to ±20V) and single-supply operation (10V to 30V), it accommodates diverse voltage requirements. Although marked Obsolete, its robust design remains relevant for legacy systems requiring reliable switching performance.

MAX333AEPP Features

• Low Leakage Current: 250pA max ensures minimal signal distortion in high-impedance circuits.
• Fast Switching: 175ns (Ton) / 145ns (Toff) enables rapid signal routing for time-critical applications.
• Low Charge Injection: 2pC reduces glitches during switching, ideal for precision data acquisition.
• Low Capacitance: 5pF (CS(off), CD(off)) minimizes crosstalk and bandwidth limitations.
• 4 Independent SPDT Switches: Integrates multiple channels in a compact 20DIP package.
• REACH Unaffected: Compliant with environmental regulations, suitable for industrial use.

MAX333AEPP Applications

• Test & Measurement Equipment: Precision signal multiplexing in oscilloscopes or data loggers.
• Audio/Video Routing: Low-distortion switching for professional AV systems.
• Industrial Control Systems: Reliable operation in harsh environments due to MSL 1 (Unlimited) moisture resistance.
• Legacy System Maintenance: Replacing older switches with superior performance metrics.
• Battery-Powered Devices: Efficient operation with ±4.5V dual supply for portable instruments.
