Description and Introduction

Low-Cost, 1%-Accurate Signal Conditioner for Piezoresistive Sensors The MAX1450EAP is a signal conditioner for piezoresistive sensors manufactured by Maxim Integrated. Below are its key specifications, descriptions, and features:

### **Specifications:**  
- **Manufacturer:** Maxim Integrated  
- **Package:** 20-pin SSOP (Shrink Small Outline Package)  
- **Operating Voltage:** 4.5V to 5.5V  
- **Operating Temperature Range:** -40°C to +125°C  
- **Sensor Excitation:** Programmable current or voltage  
- **Gain Range:** 38V/V to 230V/V (programmable)  
- **Offset Compensation:** ±60mV (programmable)  
- **Output Voltage Range:** 0.5V to 4.5V (ratiometric to supply)  
- **Digital Interface:** SPI-compatible for calibration  
- **Resolution:** 16-bit (for calibration coefficients)  
- **Power Consumption:** Typically 2.5mA  

### **Descriptions:**  
The MAX1450EAP is a highly integrated analog sensor signal conditioner designed for piezoresistive transducers. It provides amplification, calibration, and temperature compensation for bridge-type sensors, such as pressure sensors. The device includes a programmable gain amplifier (PGA), offset compensation, and a 16-bit digital calibration interface.  

### **Features:**  
- **Sensor Compensation:** Compensates for offset, span, and temperature drift.  
- **Flexible Excitation:** Supports both current and voltage excitation for the sensor bridge.  
- **High Accuracy:** 16-bit calibration resolution ensures precise signal conditioning.  
- **Ratiometric Output:** Output is referenced to the supply voltage for improved noise immunity.  
- **SPI Interface:** Allows digital calibration and configuration.  
- **Wide Temperature Range:** Suitable for industrial and automotive applications.  
- **Low Power Consumption:** Ideal for battery-powered systems.  

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