Description

The MCP9700/01 low-cost, low-power and tiny tem-

perature sensor family converts temperature to an

analog voltage. It provides an accuracy of ±4°C from

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

current.

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.

Unlike resistive sensors such as thermistors, this

family does not require a signal conditioning circuit.

The voltage output pin can be directly connected to an

ADC input of a 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.

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.
