Description and Introduction

8th-Order, Lowpass, Switched-Capacitor Filters The MAX291CPA is a low-pass filter manufactured by Maxim Integrated (now part of Analog Devices). Below are the factual details about the device:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (now Analog Devices)  
- **Type:** 8th-Order, Low-Pass, Switched-Capacitor Filter  
- **Cutoff Frequency Range:** 0.1Hz to 25kHz (programmable via external clock)  
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (typical)  
- **Supply Voltage Range:** ±5V (dual supply) or +5V (single supply)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 8  
- **Output Drive Capability:** ±5mA  
- **THD (Total Harmonic Distortion):** 0.8% (typical)  
- **Stopband Attenuation:** -80dB (typical)  

### **Descriptions:**  
The MAX291CPA is an 8th-order, low-pass, switched-capacitor filter that provides Butterworth response characteristics. It is designed for anti-aliasing and signal reconstruction applications. The cutoff frequency is set by an external clock signal, making it highly flexible for different frequency requirements.  

### **Features:**  
- **8th-Order Low-Pass Filter** – Provides sharp roll-off for effective signal conditioning.  
- **Butterworth Response** – Maximally flat passband with no ripple.  
- **Clock-Tunable Cutoff Frequency** – Adjustable via an external clock (100:1 ratio).  
- **Single or Dual Supply Operation** – Supports ±5V or +5V operation.  
- **Low Power Consumption** – Typically 20mA supply current.  
- **No External Components Required** – Internal clock oscillator simplifies design.  
- **Pin-Compatible with MF10** – Allows for easy replacement in existing designs.  

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

### **Specifications:**  
- **Manufacturer:** Maxim Integrated (Analog Devices)  
- **Type:** 8th-Order, Low-Pass, Switched-Capacitor Filter  
- **Cutoff Frequency Range:** Adjustable from 0.1 Hz to 25 kHz  
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (fixed)  
- **Supply Voltage Range:** ±5V to ±8V (dual supply) or +5V to +16V (single supply)  
- **Operating Temperature Range:** 0°C to +70°C  
- **Package:** 8-Pin PDIP (Plastic Dual In-Line Package)  
- **Pin Count:** 8  
- **Input Impedance:** 10 MΩ (typical)  
- **Total Harmonic Distortion (THD):** 0.8% (typical)  
- **Signal-to-Noise Ratio (SNR):** 80 dB (typical)  
- **Power Consumption:** 20 mW (typical)  

### **Descriptions:**  
The MAX291CPA is a monolithic, 8th-order, low-pass filter designed for precision signal processing applications. It uses a switched-capacitor architecture, allowing the cutoff frequency to be easily adjusted via an external clock signal. The device is commonly used in anti-aliasing, noise reduction, and data acquisition systems.  

### **Features:**  
- **8th-Order Elliptic Low-Pass Response**  
- **No External Components Required for Filtering**  
- **Adjustable Cutoff Frequency via External Clock**  
- **Low Noise and Distortion**  
- **Single or Dual Supply Operation**  
- **Pin-Compatible with MF10 and Other Industry-Standard Filters**
