Description and Introduction

Digitally Adjustable LCD Bias Supply The MAX749CSA is a dual, second-order, switched-capacitor filter manufactured by Maxim Integrated. Here are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Dual, Second-Order, Switched-Capacitor Filter  
- **Package:** 8-Pin SOIC  
- **Operating Voltage Range:** ±2.5V to ±5.5V (Dual Supply) or +5V to +11V (Single Supply)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Cutoff Frequency Range:** 0.1Hz to 30kHz (Adjustable via External Clock)  
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (Typical)  
- **Total Harmonic Distortion (THD):** <0.1% (Typical)  
- **Power Supply Rejection Ratio (PSRR):** 60dB (Typical)  
- **Supply Current:** 6mA (Typical, per Filter)  

### **Descriptions:**  
The MAX749CSA is a versatile dual switched-capacitor filter that provides two independent second-order filter sections. It can be configured as a lowpass, highpass, bandpass, or notch filter. The device operates with either a single or dual power supply and offers precise frequency control via an external clock.  

### **Features:**  
- **Dual Independent Second-Order Filters**  
- **Programmable Cutoff Frequency via External Clock**  
- **Low THD (<0.1%)**  
- **Wide Operating Voltage Range**  
- **Low Power Consumption**  
- **No External Components Required for Filtering**  
- **Available in 8-Pin SOIC Package**

Description and Introduction

Digitally Adjustable LCD Bias Supply The MAX749CSA is a precision, dual, second-order, switched-capacitor filter manufactured by Maxim Integrated.  

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Dual, Second-Order Switched-Capacitor Filter  
- **Package:** 8-Pin SOIC (Small Outline Integrated Circuit)  
- **Operating Voltage:** ±2.375V to ±5.5V (Dual Supply) or +4.75V to +11V (Single Supply)  
- **Cutoff Frequency Range:** 0.1Hz to 30kHz  
- **Filter Type:** Lowpass, Highpass, Bandpass, Notch, or Allpass (configurable)  
- **Clock-to-Cutoff Ratio:** 100:1 (adjustable)  
- **Total Harmonic Distortion (THD):** 0.02% (typical)  
- **Power Consumption:** 4.5mA (typical, ±5V supply)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions and Features:**  
- The MAX749CSA provides two independent, second-order filter sections that can be cascaded for higher-order filtering.  
- It supports multiple filter responses (lowpass, highpass, bandpass, notch, or allpass) by configuring external resistors.  
- The device operates with either a single or dual power supply.  
- Features low noise and low distortion, making it suitable for precision signal conditioning.  
- Includes an internal clock oscillator or accepts an external clock for cutoff frequency control.  
- Ideal for applications such as anti-aliasing, noise reduction, and tone detection.
