Frequently Asked Questions
What is the output sensitivity of MCP9700AT-E/TT and how does it interface with a microcontroller ADC?
The MCP9700AT-E/TT produces 10 mV/°C output sensitivity with a 500 mV offset at 0°C. This linear analog output connects directly to any ADC input, requiring no I2C or SPI peripheral. A 10-bit ADC running from a 3.3 V reference resolves approximately 0.3°C per LSB, which is sufficient for HVAC and consumer temperature monitoring applications.
Over what temperature range and supply voltage can MCP9700AT-E/TT operate reliably?
The MCP9700AT-E/TT operates from -40°C to +125°C and accepts a supply voltage of 2.3 V to 5.5 V. Its maximum accuracy specification of ±4°C applies across this full range without user calibration, and the device maintains linearity over the entire 165°C measurement span, making it reliable in both outdoor and industrial temperature monitoring installations.
How does MCP9700AT-E/TT compare to an NTC thermistor when designing a low-component-count PCB?
Unlike an NTC thermistor, the MCP9700AT-E/TT provides a linear 10 mV/°C output that requires no look-up table or Steinhart-Hart linearization in firmware. It also needs only a single decoupling capacitor and no precision resistor divider, reducing the total BOM to 3 pins from the SOT-23-3 package and simplifying production testing compared to a thermistor-and-resistor network.
What packaging and tape-reel options are available for MCP9700AT-E/TT in high-volume production?
The MCP9700AT-E/TT is supplied in a SOT-23-3 package with a 2.9 mm body length and 1.3 mm width, which fits standard 8 mm tape-and-reel reels for automated pick-and-place assembly. The T suffix in the part number confirms tape-and-reel packaging, with standard quantities of 3000 units per reel for high-volume production runs.
