MCP9700/01

Low-Power Linear Active Thermistor™ ICs

Features

Description

• Tiny Analog Temperature Sensor

• Available Packages: SC70-5

• Wide Temperature Measurement Range:

- -40°C to +125°C

The MCP9700/01 Linear Active Thermistor™

Intergrated Circuit (IC) is an analog temperature sen-

sor that converts temperature to analog voltage. It’s a

low-cost, low-power sensor with an accuracy of ±4°C

from 0°C to +70°C while consuming 6 µA (typ.) of

operating current.

• Accuracy: ±4°C (max.), 0°C to +70°C

• Optimized for Analog-to-Digital Converters

(ADCs):

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

- MCP9700: 10.0 mV/°C (typ.)

- MCP9701: 19.5 mV/°C (typ.)

• Wide Operating Voltage Range:

- MCP9700: V_DD= 2.3V to 5.5V

- MCP9701: V_DD= 3.1V to 5.5V

• Low Operating Current: 6 µA (typ.)

• Optimized to Drive Large Capacitive Loads

directly connected to the ADC input of

microcontroller. The MCP9700 and MCP9701

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.

The MCP9700/01 provides a low-cost solution for

applications that require measurement of a relative

change of temperature. When measuring relative

change in temperature from +25°C, an accuracy of

±1°C (typ.) 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

• Office Equipment

• Battery Packs and Portable Equipment

• General Purpose Temperature Monitoring

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.
