Overview
The AD22103KRZ, produced by Analog Devices Inc., is a monolithic temperature sensor with on-chip signal conditioning. This device operates over a temperature range of 0°C to +100°C, making it suitable for various 3.3 V applications. The on-chip signal conditioning eliminates the need for trimming, buffering, or linearization circuitry, simplifying system design and reducing overall system cost. The output voltage is proportional to the temperature times the supply voltage, making it a cost-effective solution when interfacing with analog-to-digital converters (ADCs).
