The MAX349EAP+T from Maxim Integrated is a high-performance, 8-channel precision analog multiplexer designed to provide superior switching performance for data acquisition systems, process controls, and instrumentation applications. This device offers a unique combination of low on-resistance, low leakage currents, and high-speed switching, making it an ideal choice for a wide range of applications where accuracy and speed are critical.

Key Features

• Low On-Resistance: The MAX349EAP+T features a low on-resistance of 100Ω max, which remains flat over the specified signal range (±15V). This ensures minimal signal distortion and preserves the integrity of the passed signal.
• Low Leakage Currents: With leakage currents as low as 2nA at +25°C, this multiplexer minimizes errors due to current leakage, thereby maintaining signal precision.
• High-Speed Switching: Fast transition times with t_ON of 250ns max and t_OFF of 175ns max, allow for rapid signal switching, which is essential for high-speed data acquisition and control systems.
• Single or Dual Supply Operation: It can operate from a single supply ranging from +4.5V to +36V or from dual supplies of ±4.5V to ±20V, offering flexibility in various circuit designs.
• ESD Protection: Integrated electrostatic discharge (ESD) protection circuitry guards the device against inadvertent static discharges.
• Low Crosstalk and Off-Isolation: These characteristics are critical in multiplexing applications to prevent signal interference between channels.
• Package: Offered in a 20-pin SSOP package, the MAX349EAP+T is designed for space-saving applications without compromising performance.
• Temperature Range: The device operates over an extended industrial temperature range of -40°C to +85°C, making it suitable for harsh environments.
