Description and Introduction

Digitally Adjustable LCD Bias Supply The MAX749 is a switched-capacitor, universal active filter manufactured by Maxim Integrated. It provides a versatile solution for designing lowpass, highpass, bandpass, and notch filters with minimal external components.  

### **Key Specifications:**  
- **Supply Voltage Range:** ±2.5V to ±6V (dual supply) or +5V to +12V (single supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Filter Types Supported:** Lowpass, Highpass, Bandpass, Notch  
- **Clock-to-Center Frequency Ratio:** 100:1 (typical)  
- **Total Harmonic Distortion (THD):** < 0.1% (typical)  
- **Signal-to-Noise Ratio (SNR):** > 80dB (typical)  
- **Power Consumption:** 12mW (typical, ±5V supply)  

### **Features:**  
- **Switched-Capacitor Architecture:** Eliminates the need for precision external components.  
- **Wide Frequency Range:** Adjustable via an external clock (up to 500kHz center frequency).  
- **Lowpass, Highpass, Bandpass, and Notch Configurations:** Selectable via pin configuration.  
- **Low Noise and Distortion:** Suitable for precision signal processing.  
- **Single or Dual Supply Operation:** Flexible power supply options.  
- **Small Footprint:** Available in 16-pin DIP and SO packages.  

The MAX749 is commonly used in audio processing, communications, and instrumentation applications where tunable filter responses are required.
