What is a ADT7410 sensor ?

The ADT7410 is a high-precision digital temperature sensor designed by Analog Devices, known for its metrological stability and exceptional linearity.

It is a factory-calibrated sensor, directly readable on the I²C or SMBus, and capable of outputting data in 16-bit signed format (resolution of 0.0078 °C per LSB).

It is used in professional measurement chains, medical systems, or calibration instruments.

Operating principle

The ADT7410 is based on a calibrated diode sensor and a 16-bit ΔΣ converter.

Each sample is processed digitally, linearized, and compensated before transmission.

Standard conversion formula:

T(°C) = Signed codex / 128

(in 16-bit mode)

💡 Each bit represents 1/128 °C, or approximately 0.0078 °C of resolution.

Example of conversion

Signed hex value Temperature (°C)
0x0000 0,0
0x0800 16,0
0x1900 50,0
0x3200 100,0
0x7D00 250,0

🧮 Format 16-bit signed, 2 bytes (MSB/LSB).

Should I choose a ADT7410 sensor ?

Strengths points

  • 🎯 Metrological precision ±0.25 K
         → Comparable to the TMP117 and MCP9808, ideal for certified measurements.
  • 🧠 16-bit resolution→ A fineness of 0.0078 °C per LSB, perfect for detecting micro-thermal variations.
  • ⚙️ Factory calibrated and compensated
         → No software calibration required — plug & play via I²C.
  • 📉 Very low drift over time
         → Typically <0.05 K/year — excellent for long-term stability.

Weaknesses points

  • 🌡️ Slow conversion time (16-bit mode)
         → Up to 240 ms, therefore not well suited for rapid measurements.
  • 📡 Interface only I²C/SMBus
         → No SPI version available.
  • 💸 Slightly higher price
         → But justified by its precision and industrial certification.

Useful information

Here is some useful information regarding the ADT7410 sensors.

Adress (hex) Name
 Function
0x00 / 0x01 Temperature MSB/LSB Temperature data (16-bit signed)
0x02 Status Indicate the end of conversion
0x03 Configuration Resolution, mode, polarity
0x04 T_HIGH High alert threshold
0x05 T_LOW Low alert threshold
0x06 T_CRIT Critical threshold
0x07 Hysteresis Hysteresis for alerts
0x0B ID Component ID 
i2c_start();
i2c_write(0x48 << 1);
i2c_write(0x00);
i2c_start();
i2c_write((0x48 << 1) | 1);
MSB = i2c_read_ack();
LSB = i2c_read_nack();
i2c_stop();

raw = (MSB << 8) | LSB;
if (raw & 0x8000) raw -= 65536; // Signed value
temp = raw / 128.0; // Mode 16 bits

✅ Exemple :

MSB = 0x19, LSB = 0x00 → (0x1900 / 128) = 50,0 °C
