AD22103 is a monolithic temperature sensor with on-chip signal conditioning. It can be operated over the temperature range 0°C to +100°C, making it ideal for use in numerous 3.3 V applications. The signal conditioning eliminates the need for any trimming, buffering or linearization.
The AD22103 temperature sensor IC provides a voltage output proportional to temperature and supply voltage, making it ideal for microprocessor‑based thermal management, battery monitoring, and system temperature compensation. It operates from a single 3.3 V supply (2.7 V‑3.6 V allowed) and delivers an output of 0.25 V at 0 °C up to 3.05 V at 100 °C.
The device features low quiescent current (350‑600 pA), high linearity (≤0.5 % FS), and built‑in ESD protection. Available in TO‑92 and SOIC‑8 packages, it can be mounted directly to a PCB or thermally attached with epoxy for improved response time. The datasheet includes absolute maximum ratings, pin descriptions, ordering information, and detailed thermal and electrical characteristics.
