MAX1452AAE+T Sensor Signal Conditioner IC - SSOP-16 SMD
MAX1452AAE+T Precision Sensor Signal Conditioner IC (SSOP-16)
The MAX1452AAE+T from Analog Devices is a highly integrated sensor signal conditioner IC designed for pressure sensors, transducers, and other resistive sensor applications. It provides analog voltage output with digital calibration, eliminating the need for external trims. With on-chip EEPROM and temperature compensation, it delivers high accuracy across a wide temperature range.

Compatibility
This IC works with standard 5V microcontrollers like Arduino, ESP32, STM32, and PIC. It outputs a conditioned analog voltage that can be read directly by ADC inputs. For digital calibration, a bidirectional serial interface is used, compatible with most MCUs supporting SPI-like communication.
Wiring Notes
Connect VDD to 5V and GND to system ground. The analog output (OUT) connects to an ADC channel. Use a 0.1ĀµF decoupling capacitor near the power pins. For serial calibration, the MAX1452 uses a single-wire bidirectional interface (DIO); pull-up resistor may be required as per datasheet.
Why Buy from Compoden
Every component is sourced from verified suppliers and tested for compatibility before listing. We've spent 10 years building projects for makers, schools, and institutions across India. Ships from Bengaluru in 3-5 days. If defective on arrival, replace within 7 days.
Is this compatible with Arduino?
Yes, the MAX1452 outputs a 0.5Vā4.5V analog signal that can be directly read by Arduino's 5V-tolerant ADC inputs. For calibration, you can use a digital I/O pin for the DIO interface with appropriate timing.
Can I use this for a 3.3V system like ESP32?
The MAX1452 operates at 5V, but the output voltage range is within 0.5Vā4.5V, so if your 3.3V ADC has enough headroom, you can directly connect it. However, ensure the ADC input can tolerate up to 4.5V; a voltage divider might be needed for safety.
Does it require external components for calibration?
No, all calibration coefficients are stored in on-chip EEPROM. Once programmed via the serial interface, no external trims or resistors are needed.
