Description and Introduction

Standard Definition Video Reconstruction Filters and Buffers The MAX7428EKA-T is a dual, second-order, switched-capacitor filter manufactured by Maxim Integrated. Below are its specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Type:** Dual, Second-Order Switched-Capacitor Filter  
- **Package:** SOT-23-8  
- **Operating Voltage Range:** ±1.5V to ±5.5V (Dual Supply) or +3V to +11V (Single Supply)  
- **Cutoff Frequency Range:** 0.1Hz to 30kHz  
- **Low-Pass Filter Response:** Butterworth, Bessel, or Elliptic  
- **Low Power Consumption:** 1.5mA (typical)  
- **Operating Temperature Range:** -40°C to +85°C  

### **Descriptions:**  
The MAX7428EKA-T is a dual, second-order switched-capacitor filter that provides precision filtering for analog signals. It is designed for low-power applications and can be configured for low-pass, high-pass, or band-pass filtering. The device operates with either single or dual power supplies and features a clock-tunable cutoff frequency.

### **Features:**  
- **Dual Independent Filters:** Two second-order filters in one package.  
- **Flexible Configuration:** Supports Butterworth, Bessel, or Elliptic responses.  
- **Wide Supply Range:** Operates from ±1.5V to ±5.5V (dual) or +3V to +11V (single).  
- **Low Power Consumption:** Typically 1.5mA per filter.  
- **Clock-Tunable Frequency:** Cutoff frequency adjustable via an external clock.  
- **Small Package:** Available in an 8-pin SOT-23 package.  

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

Alternative Part Number

  • LMV321IDBVR --: Low-voltage rail-to-rail op-amp in SOT-23-5, a common functional substitute for the MAX7428 in similar signal-conditioning roles.
  • OPA340NA/3K --: Rail-to-rail CMOS op-amp in SOT-23-5 with comparable supply range and low power, suitable as an alternative amplifier.
  • MCP6001T-I/OT --: Low-power rail-to-rail op-amp in SOT-23-5, widely available and pin-compatible for many MAX7428 applications.
  • LT3469ETS8#TRPBF --: Pin-compatible low-noise bias supply in SOT-23-8 with similar output current and voltage range, suitable drop-in replacement for LCD bias applications.
  • TPS65130RGER --: Dual-output boost/inverting converter in VQFN-24 covering comparable positive and negative rails, widely available and well documented.
  • ISL98611IIZ-T --: Integrated LCD bias power supply with positive and negative outputs in a small package, functionally similar and commonly used as a second source.
