8th-Order, Lowpass, Switched-Capacitor Filters The **MAX292CSA** is a **4th-order, lowpass, switched-capacitor filter** manufactured by **Maxim Integrated (now part of Analog Devices)**.  

### **Key Specifications:**  
- **Filter Type:** 4th-order, lowpass, Butterworth response  
- **Cutoff Frequency Range:** Adjustable from **0.1Hz to 25kHz**  
- **Clock-to-Cutoff Frequency Ratio:** **100:1** (typical)  
- **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 SOIC (CSA)**  
- **Total Harmonic Distortion (THD):** **0.1% (typical)**  
- **Signal-to-Noise Ratio (SNR):** **80dB (typical)**  
- **Power Consumption:** **5mA (typical) at ±5V**  

### **Features:**  
- **Self-contained filter** – Requires no external components except a clock source  
- **Low noise and distortion** – Suitable for precision signal processing  
- **Easy clock tuning** – Cutoff frequency set by an external clock  
- **Single or dual-supply operation** – Flexible power supply options  
- **High accuracy** – Tightly controlled frequency response  

### **Applications:**  
- **Anti-aliasing filters**  
- **Data acquisition systems**  
- **Speech and audio processing**  
- **Medical instrumentation**  
- **Communication systems**  

The **MAX292CSA** is designed for applications requiring **high-performance, low-noise filtering** with minimal external components.
