Description and Introduction

5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters The MAX7427CUA is a precision, dual-channel, digital temperature sensor manufactured by Maxim Integrated (now part of Analog Devices). Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Part Number:** MAX7427CUA  
- **Package:** 8-pin µMAX®  
- **Operating Voltage Range:** 2.7V to 5.5V  
- **Temperature Measurement Range:** -55°C to +125°C  
- **Temperature Accuracy:** ±1°C (from -10°C to +85°C)  
- **Resolution:** 0.0625°C (12-bit digital output)  
- **Interface:** I²C-compatible (2-wire serial)  
- **Supply Current:** 200µA (typical)  
- **Shutdown Current:** 1µA (typical)  

### **Descriptions:**  
The MAX7427CUA is a low-power, high-accuracy digital temperature sensor with an I²C interface. It provides precise temperature measurements with minimal power consumption, making it suitable for battery-powered and portable applications. The device includes an on-chip temperature sensor and a 12-bit ADC for digital conversion.

### **Features:**  
- Dual-channel temperature sensing (internal + external diode)  
- Programmable overtemperature alarm with hysteresis  
- Low operating current (200µA typical)  
- Wide supply voltage range (2.7V to 5.5V)  
- Small 8-pin µMAX package  
- I²C-compatible serial interface  
- High accuracy (±1°C from -10°C to +85°C)  
- Shutdown mode for power savings

- **Cutoff Frequency Range:** 0.1Hz to 20kHz  
- **Filter Type:** Lowpass, Highpass, Bandpass, Notch, or Allpass  
- **Clock-to-Cutoff Frequency Ratio:** 100:1 (Typical)  
- **Total Harmonic Distortion (THD):** -80dB (Typical)  
- **Signal-to-Noise Ratio (SNR):** 80dB (Typical)  
- **Operating Temperature Range:** 0°C to +70°C  

### **Descriptions:**  
The MAX7427CUA is a versatile dual switched-capacitor filter that can be configured for various filter responses, including lowpass, highpass, bandpass, notch, and allpass. It operates with either single or dual power supplies and provides precise filtering with minimal external components.  

### **Features:**  
- Dual second-order filter sections in a single IC  
- Independently programmable cutoff frequencies  
- Low noise and distortion  
- No external components required for filter response  
- Low power consumption  
- Pin-compatible with industry-standard MF10
