-VDD = 2.3V to 5.5V (MCP9700/9700A)
-VDD = 3.1V to 5.5V (MCP9701/9701A) Low Operating Current: 6 ВµA (typical) Optimized to Drive Large Capacitive Loads MCP9700/9700A and MCP9701/9701A sensors with
Linear Active Thermistor Integrated Circuit (IC) comprise a family of analog temperature sensors that
convert temperature to analog voltage.
The low-cost, low-power sensors feature an accuracy
of В±2В°C from 0В°C to +70В°C (MCP9700A/9701A) and
В±4В°C from 0В°C to +70В°C (MCP9700/9701) while
consuming 6 ВµA (typical) of operating current.
Unlike resistive sensors, e.g., thermistors, the Linear
Active Thermistor IC does not require an additional
signal-conditioning circuit. Therefore, the biasing circuit …
