### **Descriptions:**
The MAX262BCWG is a versatile, digitally programmable active filter that allows users to configure various filter responses (lowpass, highpass, bandpass, notch, and allpass) using an external clock and digital control inputs. It integrates two second-order filter sections, enabling the implementation of higher-order filters when cascaded. The device is designed for precision signal conditioning in communication, instrumentation, and audio applications.
### **Features:**
- **Digitally Programmable Filter Parameters:** Center frequency (f₀) and Q factor can be adjusted via a 6-bit parallel interface.
- **Wide Frequency Range:** Supports center frequencies up to 140kHz.
- **Multiple Filter Responses:** Configurable as lowpass, highpass, bandpass, notch, or allpass.
- **Low Distortion:** THD (Total Harmonic Distortion) typically < 0.1%.
- **Low Noise:** Input-referred noise of 40µV (Typical).
- **Single or Dual Supply Operation:** Compatible with ±5V or +10V supplies.
- **Cascadable:** Two independent second-order sections allow for higher-order filter designs.
