TITMP235AQDBZRQ1
Overview
The TMP235AQDBZRQ1 is an automotive-qualified, high-precision analog output temperature sensor designed for linear temperature-to-voltage conversion. It operates over a wide range of -40 to +125 degrees Celsius with a positive slope of 10mV per degree Celsius, making it compatible with standard microcontroller ADC inputs. This AEC-Q100 qualified device is functional-safety-capable and features an extremely low quiescent current of 14.5 microamps.
Why Choose This Part
The sensor offers an excellent balance of low power consumption and high accuracy without the complexity of digital communication protocols. Its functional-safety-capable status and AEC-Q100 Grade 1 qualification make it a reliable choice for mission-critical automotive and industrial applications. The linear 10mV per degree Celsius output simplifies software development by requiring only a basic linear transfer function for ADC conversion.
Applications
Key Specifications
Getting Started
To integrate this sensor, connect the VDD pin to a stable 2.3V to 5.5V supply and the VOUT pin to a high-impedance ADC input on your microcontroller. Place a 0.1 microfarad ceramic bypass capacitor close to the VDD pin to minimize noise. Calibration is typically not required for standard precision needs, as the device is factory-trimmed for a 0.5 percent accuracy profile.
