MCP9700/9700A  
MCP9701/9701A  
Low-Power Linear Active Thermistor™ ICs  
Features  
Description  
• Tiny Analog Temperature Sensor  
• Available Packages:  
The MCP9700/9700A and MCP9701/9701A family of  
Linear Active Thermistor™ Intergrated Circuit (IC) is an  
analog temperature sensor that converts temperature  
to analog voltage. It’s a low-cost, low-power sensor  
with an accuracy of ±2°C from 0°C to +70°C  
(MCP9700A/9701A) ±4°C from 0°C to +70°C  
(MCP9700/9701) while consuming 6 µA (typical) of  
operating current.  
- SC70-5, SOT-23-5, TO-92-3  
• Wide Temperature Measurement Range:  
- -40°C to +125°C (Extended Temperature)  
- -40°C to +150°C (High Temperature)  
(MCP9700/9700A)  
• Accuracy:  
Unlike resistive sensors (such as thermistors), the  
Linear Active Thermistor IC does not require an  
additional signal-conditioning circuit. Therefore, the  
biasing circuit development overhead for thermistor  
solutions can be avoided by implementing this low-cost  
device. The voltage output pin (VOUT) can be directly  
connected to the ADC input of a microcontroller. The  
MCP9700/9700A and MCP9701/9701A temperature  
coefficients are scaled to provide a 1°C/bit resolution  
for an 8-bit ADC with a reference voltage of 2.5V and  
5V, respectively.  
- ±2°C (max.), 0°C to +70°C (MCP9700A/9701A)  
- ±4°C (max.), 0°C to +70°C (MCP9700/9701)  
• Optimized for Analog-to-Digital Converters  
(ADCs):  
- 10.0 mV/°C (typical) MCP9700/9700A  
- 19.5 mV/°C (typical) MCP9701/9701A  
• Wide Operating Voltage Range:  
- VDD = 2.3V to 5.5V MCP9700/9700A  
- VDD = 3.1V to 5.5V MCP9701/9701A  
• Low Operating Current: 6 µA (typical)  
• Optimized to Drive Large Capacitive Loads  
The MCP9700/9700A and MCP9701/9701A provide a  
low-cost solution for applications that require measure-  
ment of a relative change of temperature. When  
measuring relative change in temperature from +25°C,  
an accuracy of ±1°C (typical) can be realized from 0°C  
to +70°C. This accuracy can also be achieved by  
applying system calibration at +25°C.  
Typical Applications  
• Hard Disk Drives and Other PC Peripherals  
• Entertainment Systems  
• Home Appliance  
In addition, this family is immune to the effects of  
parasitic capacitance and can drive large capacitive  
loads. This provides Printed Circuit Board (PCB) layout  
design flexibility by enabling the device to be remotely  
located from the microcontroller. Adding some  
capacitance at the output also helps the output  
transient response by reducing overshoots or  
undershoots. However, capacitive load is not required  
for sensor output stability.

• Battery Packs and Portable Equipment  
• General Purpose Temperature Monitoring
