Description

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)

(MCP9700/9701) while consuming 6 µA (typ.) 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 (V

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 measure-

ment of a relative change of temperature. When mea-

suring 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.

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

undershoots. However, capacitive load is not required

for sensor output stability.
