Descriptions:

The MAX749CPA+ is a versatile, dual, second-order switched-capacitor filter that can be configured for various filter responses (lowpass, highpass, bandpass, notch, or allpass). It operates with a single or dual power supply and provides precise filtering with minimal external components.

Features:

• Dual Second-Order Filter Sections – Allows cascading for higher-order filters.
• Wide Frequency Range – Adjustable from 0.1Hz to 30kHz.
• Low Power Consumption – Suitable for battery-powered applications.
• Single or Dual Supply Operation – Supports ±5V to ±8V (dual) or +5V to +16V (single).
• No External Clock Required – Internal oscillator simplifies design.
• Low THD (Total Harmonic Distortion) – Ensures clean signal filtering.
• Easy to Configure – Minimal external components needed for operation.
