Low-Power Linear Active Thermistor™ ICs
Features
Description
• Tiny Analog Temperature Sensor
• Available Packages:
- 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:
- ±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 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.
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.
The MCP9700/9700A and MCP9701/9701A provide 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 (typical) can be realized from 0°C
to +70°C. This accuracy can also be achieved by
applying system calibration at +25°C.

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.

APPLICATIONS INFORMATION
The Linear Active Thermistor™ IC uses an internal
diode to measure temperature. The diode electrical
characteristics have a temperature coefficient that
provides a change in voltage based on the relative
ambient temperature from -40°C to 150°C. The change
in voltage is scaled to a temperature coefficient of
10.0 mV/°C (typical) for the MCP9700/9700A and
19.5 mV/°C (typical) for the MCP9701/9701A. The output voltage at 0°C is also scaled to 500 mV (typical)
and 400 mV (typical) for the MCP9700/9700A and
MCP9701/9701A, respectively. This linear scale is
described in the first-order transfer function shown in
Equation 4-1 and Figure 2-16.

Relative Accuracy to +25°C
The change in accuracy from the calibration
temperature is due to the output non-linearity from the
first-order equation, as specified in Equation 4-2. The
accuracy can be further improved by compensating for
the output non-linearity.
For higher accuracy using a sensor compensation
technique, refer to AN1001 “IC Temperature Sensor
Accuracy
Compensation
with
a
PICmicro®
Microcontroller” (DS01001). The application note
shows that if the MCP9700 is compensated in addition
to room temperature calibration, the sensor accuracy
can be improved to ±0.5°C (typical) accuracy over the
operating temperature (Figure 4-3).

Improving Accuracy
The MCP9700/9700A and MCP9701/9701A accuracy
can be improved by performing a system calibration at
a specific temperature. For example, calibrating the
system at +25°C ambient improves the measurement
accuracy to a ±0.5°C (typical) from 0°C to +70°C, as
shown in Figure 4-2. Therefore, when measuring
relative temperature change, this family measures
temperature with higher accuracy.

4.2
Shutdown Using Microcontroller
I/O Pin
The MCP9700/9700A and MCP9701/9701A family of
low operating current of 6 µA (typical) makes it ideal for
battery-powered
applications.
However,
for
applications that require tighter current budget, this
device can be powered using a microcontroller Input/
Output (I/O) pin. The I/O pin can be toggled to shut
down the device. In such applications, the
microcontroller internal digital switching noise is
emitted to the MCP9700/9700A and MCP9701/9701A
as power supply noise. This switching noise compromises measurement accuracy. Therefore, a decoupling
capacitor and series resistor will be necessary to filter
out the system noise.
4.3
Layout Considerations
The MCP9700/9700A and MCP9701/9701A family
does not require any additional components to operate.
However, it is recommended that a decoupling
capacitor of 0.1 µF to 1 µF be used between the VDD
and GND pins. In high-noise applications, connect the
power supply voltage to the VDD pin using a 200Ω
resistor with a 1 µF decoupling capacitor. A high
frequency ceramic capacitor is recommended. It is
necessary for the capacitor to be located as close as
possible to the VDD and GND pins in order to provide
effective noise protection. In addition, avoid tracing
digital lines in close proximity to the sensor.
4.4
Thermal Considerations
The MCP9700/9700A and MCP9701/9701A family
measures temperature by monitoring the voltage of a
diode located in the die. A low-impedance thermal path
between the die and the PCB is provided by the pins.
Therefore, the sensor effectively monitors the
temperature of the PCB. However, the thermal path for
the ambient air is not as efficient because the plastic
device package functions as a thermal insulator from
the die. This limitation applies to plastic-packaged
silicon temperature sensors. If the application requires
measuring ambient air, consider using the TO-92
package.
The MCP9700/9700A and MCP9701/9701A is
designed to source/sink 100 µA (max.). The power
dissipation due to the output current is relatively
insignificant. The effect of the output current can be
described using Equation 4-2.
EQUATION 4-2:
EFFECT OF SELFHEATING
T J – T A = θ JA ( V DD I DD + ( V DD – V OUT ) I OUT )
Where:
TJ = Junction Temperature
TA = Ambient Temperature
θJA = Package Thermal Resistance
(331°C/W)
VOUT = Sensor Output Voltage
IOUT = Sensor Output Current
IDD = Operating Current
VDD = Operating Voltage
At TA = +25°C (VOUT = 0.75V) and maximum
specification of IDD = 12 µA, VDD = 5.5V and
IOUT = +100 µA, the self-heating due to power
dissipation (TJ – TA) is 0.179°C.
