AD7814:  Temperature Sensor: 10-Bit Digital in 6-Lead SOT-23

Product Details


The AD7814 is a complete temperature monitoring system in a SOT-23 package or 8-lead µSOIC package. It contains a bandgap temperature sensor and 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25 °C. The measurable temperature range is -40°C to +125°C, with a ±2°C temperature accuracy. The AD7814 features a standby mode that reduces the current consumption to 1 µA.
