Description
Linear Active Thermistor™ ICs are sensors whose output voltage is directly proportional to measured temperature. The MCP9700A can accurately measure temperature from -40C to +150C. The output of the MCP9700A is calibrated to a slope of 10mV/°C and has a DC offset of 500mV. The offset allows reading negative temperatures without the need for a negative supply. The MCP9700A is packaged in space saving 5-pin SC-70, and 3-ld TO-92 packages.

Engineer Comments

Traditional NTC or PTC thermistors are relatively basic components - they are but a resistor who changes its value as the temperature of the substrate is modified by the environment. Should you still be working with an analog signal acquisition system, giving the MCP9700 a chance might be a good idea.

The innovation in Microchip's approach is that the MCP9700 is not a simple slab of thermo-sensitive material. Instead, the American semiconductor powerhouse embeds a relatively complex set of logic along with the actual semiconductor sensing element.

This way, developers and users do not need to worry much about keeping accuracy high. The datasheet promises an average accuracy of but two degrees over an extremely wide temperature range; this makes the MCP9700 a high accuracy analog temperature sensor ideally suited to applications where an ADC is available.

One example for this would be an MCP9700 Arduino camera sensor - the Arduino already has an ADC, so measuring the voltage provided by the MCP9700 sensor is not a significant cost burden. Do, however, also keep digital sensors at the back of your head - TCO, after all, is and remains a factor...

Description
MCP9700/9700A and MCP9701/9701A sensors with Linear Active Thermistor™ Integrated Circuit (IC) com- prise a family of analog temperature sensors that convert temperature to analog voltage. The low-cost, low-power sensors feature an accuracy of ±2°C from 0°C to +70°C (MCP9700A/9701A) and ±4°C from 0°C to +70°C (MCP9700/9701) while consuming 6 µA (typical) of operating current. Unlike resistive sensors, e.g., thermistors, the Linear Active Thermistor IC does not require an additional sig- nal-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, respec- tively. The MCP9700/9700A output 0.1°C/bit for a 12- bit ADC with 4.096V reference. 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 (typical) 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 para- sitic 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, capaci- tive load is not required for the stability of sensor out- put.
