The MAX6612 is a low-power precision analog output temperature sensor from Texas Instruments. It has high accuracy and stability, and its operating temperature range is -10°C to +125°C.
The MAX6612 is a precision analog output temperature sensor packaged in a 5‑pin SC70. It provides a linear voltage output proportional to temperature with a high sensitivity of 19.53 mV/°C and a 400 mV offset at 0 °C, enabling direct interfacing to ADCs.
Key features include operation over a wide temperature range (‑55 °C to +150 °C), low supply current (35 µA no‑load), ability to drive high‑capacitive loads (≥1000 pF), and a small footprint. Typical applications are base stations, industrial equipment, home appliances, and other systems requiring accurate temperature monitoring.
| Supply voltage range | 2.4 V to 5.5 V |
|---|---|
| No‑load supply current | 35 µA |
| Output voltage at 0 °C | 400 mV |
| Operating temperature range | -55 °C to +150 °C |
| Turn‑on time (CLOAD=1000 pF) | 80 µs |
| Shutdown current (VCC < 0.8 V) | 1 µA |
V_OUT = 0.40 V + (0.01953 V/°C × T) – (2 × 10⁻⁶ × T²).
The device draws 35 µA of supply current when no load is connected.
A supply voltage of 5.5 V enables operation from –10 °C to +150 °C.
