Digital Temperature Sensors Offer 0.5°C Accuracy
The ADT7310 and ADT7410 are digital temperature sensors offering industry-leading temperature accuracy of ±0.5°C over a –40°C to +105°C operating range. The devices contain a band gap temperature sensor and a 13-bit ADC to monitor and digitize the temperature to a resolution of 0.0625°C. Alternatively, the resolution can be configured to 16 bits to give a 0.0078°C resolution. Also included is a preset critical overtemperature indicator, which is set to +147°C, along with a programmable overtemperature and undertemperature interrupt functionality. The parts are specified for operation from –55°C to +150°C with operating voltage from 2.7 V to 5.5 V. The ADT7310 has an SPI interface, and the ADT7410 has an I2C interface. Both are available in an 8-lead, narrow SOIC package.
ADT7410 Features
Quad SPST Switches Offer Industry-Leading 2 Ω Max On Resistance in Small Packages ADI's iCMOS™ manufacturing process allows for the development of ICs that offer industry-leading performance in very small form factors enabling board area space savings. This proprietary process technology enables the production of switches and multiplexers that offer ultralow power dissipation, making the parts ideally suited for portable and battery-powered instruments. Our ADG1611 device contains four independent single-pole/single-throw (SPST) switches. It offers 1 Ω typical on resistance and 0.2 Ω on resistance flatness over the full signal range. The ultralow on resistance of these switches makes them ideal solutions for data acquisition and gain switching applications where low on resistance and distortion is critical. The on resistance profile is very flat over the full analog input range, ensuring excellent linearity and low distortion when switching audio signals. The ADG1611 is specified for –40°C to +125°C operation and has a continuous current specification of 280 mA. Other products in the family—ADG1612 and ADG1613—offer alternate logic inversion options.
