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 (V_OUT) 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:

- V_DD= 2.3V to 5.5V MCP9700/9700A

- V_DD= 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.

• Office Equipment

• Battery Packs and Portable Equipment

• General Purpose Temperature Monitoring
