5th-Order, Lowpass, Switched-Capacitor Filters The MAX7414CUA is a fifth-order, lowpass, switched-capacitor filter (SCF) manufactured by Maxim Integrated (now part of Analog Devices). Below are its specifications, descriptions, and features based on Ic-phoenix technical data files:
### **Specifications:**
- **Manufacturer:** Maxim Integrated (now Analog Devices)
- **Part Number:** MAX7414CUA
- **Package:** 8-pin μMAX
- **Filter Type:** Fifth-order, lowpass, switched-capacitor filter (SCF)
- **Cutoff Frequency Range:** 0.1Hz to 25kHz (adjustable via external clock)
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (typical)
- **Supply Voltage Range:** ±2.375V to ±5.5V (dual supply) or +4.75V to +11V (single supply)
- **Operating Temperature Range:** -40°C to +85°C
- **Power Consumption:** 4.5mA (typical at ±5V supply)
- **Stopband Attenuation:** -82dB (typical at 4 × f₀)
- **Input Noise:** 60μVrms (typical)
### **Descriptions:**
The MAX7414CUA is a monolithic, fifth-order, lowpass filter designed for precision signal processing applications. It uses a switched-capacitor architecture to provide a sharp roll-off and low passband ripple. The cutoff frequency is set by an external clock signal, making it highly flexible for various filtering needs. It operates from dual or single power supplies and is suitable for anti-aliasing, data acquisition, and noise reduction applications.
### **Features:**
- **Fifth-Order Lowpass Response:** Provides a sharp roll-off (-60dB/decade).
- **Adjustable Cutoff Frequency:** Set by an external clock (100:1 clock-to-cutoff ratio).
- **Low Noise and Distortion:** Suitable for high-precision applications.
- **Wide Supply Range:** Supports ±2.375V to ±5.5V (dual) or +4.75V to +11V (single).
- **Low Power Consumption:** 4.5mA typical at ±5V.
- **High Stopband Attenuation:** -82dB typical at 4 × f₀.
- **Compact Package:** 8-pin μMAX for space-constrained designs.
