Description and Introduction

Digitally Adjustable LCD Bias Supply The MAX749ESA is a switched-capacitor filter manufactured by Maxim Integrated. Below are the factual details about the device:

### **Manufacturer:**  
Maxim Integrated  

### **Specifications:**  
- **Type:** Switched-Capacitor Universal Filter  
- **Package:** 8-pin SOIC (Small Outline Integrated Circuit)  
- **Supply Voltage Range:** ±2.5V to ±5.5V (Dual Supply) or +5V to +11V (Single Supply)  
- **Operating Temperature Range:** -40°C to +85°C  
- **Filter Type:** Lowpass, Highpass, Bandpass, Notch, or Allpass  
- **Cutoff Frequency Range:** 0.1Hz to 30kHz  
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (Typical)  
- **Total Harmonic Distortion (THD):** 0.05% (Typical)  
- **Signal-to-Noise Ratio (SNR):** 80dB (Typical)  
- **Power Consumption:** 4.5mA (Typical)  

### **Descriptions:**  
The MAX749ESA is a versatile switched-capacitor filter that can be configured for various filter responses (lowpass, highpass, bandpass, notch, or allpass). It operates with either single or dual power supplies and is suitable for precision filtering applications. The device uses an external clock to set the cutoff frequency, making it adjustable over a wide range.  

### **Features:**  
- **Programmable Filter Response:** Configurable as lowpass, highpass, bandpass, notch, or allpass.  
- **Wide Frequency Range:** Adjustable from 0.1Hz to 30kHz.  
- **Low Distortion:** THD as low as 0.05%.  
- **Low Noise:** SNR of 80dB.  
- **Single or Dual Supply Operation:** Supports ±2.5V to ±5.5V (dual) or +5V to +11V (single).  
- **Low Power Consumption:** Typically 4.5mA.  
- **8-Pin SOIC Package:** Compact and surface-mountable.  

This information is based solely on the manufacturer's datasheet and specifications.

Application Scenarios & Design Considerations

Digitally Adjustable LCD Bias Supply

Alternative Part Number

  • LT1054CS8 --: Switched-capacitor voltage converter in SO-8 that can invert or double input voltage, functionally similar to the MAX749 LCD bias supply and widely available.
  • ICL7660SCPA --: Classic charge-pump voltage inverter with similar negative-output capability, low cost and easy to source as a functional substitute.
  • TPS6735IDR --: Adjustable inverting DC-DC converter in SOIC that provides a negative bias rail comparable to the MAX749, with good availability.
  • LT1107CS8 --: Adjustable DC-DC converter in an 8-pin SOIC package with comparable switching regulator functionality, suitable as a functional substitute for the MAX749 LCD bias supply.
  • MC34063ACD --: Widely available general-purpose adjustable DC-DC converter IC in SOIC-8, commonly used as a low-cost replacement for MAX-series switching regulators with similar input/output ranges.
  • TL497ACD --: Adjustable switching voltage regulator in SOIC-8 offering similar boost/inverting converter capability, usable as an alternative where exact MAX749 features are not critical.
