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

Application Scenarios & Design Considerations

5th-Order, Lowpass, Elliptic, Switched-Capacitor Filters

Alternative Part Number

  • LTC1563-2IGN --: Pin-compatible low-pass switched-capacitor filter with similar cutoff range and supply voltage, from a different series and manufacturer.
  • AD8620ARZ --: Low-noise precision op-amp usable in the same filter signal path, offering comparable bandwidth and supply range as a functional substitute.
  • TLV2372IDGKR --: Rail-to-rail low-power op-amp with similar supply and bandwidth characteristics, suitable as a lower-cost alternative in the same circuit.
  • LTC1563-2CGN --: Pin-compatible low-pass switched-capacitor filter in the same 8-pin package class, widely used as a MAX7427 substitute with similar cutoff range.
  • LTC1060CN --: Versatile dual switched-capacitor filter that can be configured to replicate the MAX7427 low-pass response, available in DIP and SO packages.
  • MF10CCN --: Classic dual switched-capacitor filter offering configurable low-pass modes, a common cross-reference for Maxim switched-capacitor filter parts.
