The 6-pin AD7414 and 5-pin AD7415 are complete temperature monitoring systems squeezed into a tiny SOT-23 package. Both contain a band-gap temperature sensor and 10-bit ADC to monitor and digitize the temperature reading to a resolution of 0.25¡C. The devices are well suited to portable applications where low power is required and size is a key factor.With its SAR architecture, each device consumes less than 3 mW power, while providing one temperature reading per second. The measurable temperature range is -40¡C to +85¡C with ±2¡C temperature accuracy. Another key feature of the devices is a two-wire serial interface, compatible with SMBus and I2C interfaces. The AD7414 also contains on-chip registers that can be programmed with high and low temperature limits. Pricing is $0.94 each/1,000 for the AD7414 and $0.92 for the AD7415.
