M117/M117B Series Digital Temperature Sensors
Product Overview
The M117 and M117B series are high-precision digital-analog mixed-signal temperature sensor chips designed for a wide operating range of -70C to +150C. Offering exceptional accuracy up to 0.1C or 0.5C without user calibration, these chips leverage CMOS semiconductor PN junction temperature characteristics and bandgap voltage relationships. They feature a 16-bit ADC with a resolution of 0.004C, providing fast temperature readings, low power consumption, and flexible programmable configurations. The integrated non-volatile E2PROM stores chip ID, alarm thresholds, calibration coefficients, and user-defined information. An ALERT pin facilitates hardware alarm extensions. These sensors are ideal for applications requiring accurate and reliable temperature monitoring, including smart wearables, medical electronics, cold chain logistics, and industrial environments.
