### **Description:**
The MAX274BCWI is a monolithic, continuous-time active filter that integrates four independently programmable biquad sections. It allows for the implementation of high-order filters (up to 8th-order) without requiring external components for tuning. The device is suitable for applications requiring precise frequency response control, such as audio processing, communications, and instrumentation.
### **Features:**
- **Integrated 4 Biquad Sections:** Enables 8th-order filter configurations.
- **No External Components Required:** Eliminates the need for capacitors or resistors for tuning.
- **Wide Frequency Range:** Supports center frequencies from 0.1Hz to 150kHz.
- **Adjustable Q and Gain:** Programmable Q-factor (0.5 to 100) and gain (-40dB to +40dB).
- **Low Power Consumption:** Typically 50mW per biquad section.
- **Single or Dual Supply Operation:** Compatible with ±5V to ±15V (dual) or +10V to +30V (single) supplies.
- **Monolithic Design:** Ensures stability and reliability.
