Frequently Asked Questions
How accurate is MCP9808T-E/MS across its full operating temperature range?
MCP9808T-E/MS provides ±1°C maximum accuracy from -20°C to +100°C and ±2°C over the full -40°C to +125°C industrial range, making it one of the more precise low-cost I2C temperature sensors available for embedded designs.
What I2C address options does MCP9808T-E/MS support, and why does that matter in multi-sensor systems?
The MCP9808T-E/MS supports 5 user-selectable I2C addresses via 3 address pins, allowing up to 5 devices on a single 2-wire bus operating at up to 400 kHz, which simplifies wiring in multi-zone thermal monitoring applications without additional multiplexers.
How does the 8-pin MSOP package affect PCB layout complexity for MCP9808T-E/MS?
The 8-pin MSOP package has a 3 mm x 3 mm body with 1.1 mm height, consuming minimal board area and enabling standard SMT reflow assembly, which is beneficial for space-constrained designs like wearables or compact industrial sensors requiring surface-mount placement.
What supply current does MCP9808T-E/MS draw in active versus shutdown modes?
MCP9808T-E/MS draws approximately 200 µA during active measurement and drops to as low as 0.1 µA in shutdown mode, making it well-suited for battery-powered applications where minimizing idle power consumption over extended monitoring intervals is a priority.
