The LTC2461/LTC2463 are ultra tiny, 16-Bit analog to digital converters with an integrated precision reference. They use a single 2.7V to 5.5V supply and communicate through an I2C Interface. The LTC2461 is single-ended with a 0V to 1.25V input range and the LTC2463 is differential with a 1.25V input range. Both ADCs include a 1.25V integrated reference with 2ppm/?C drift performance and 0.1% initial accuracy. The converters are available in a 12-pin 3mm ? 3mm DFN package or an MSOP-12 package. They include an integrated oscillator and perform conversions with no latency for multiplexed applications. The LTC2461/LTC2463 include a proprietary input sampling scheme that reduces the average input current several orders of magnitude when compared to conventional delta sigma converters.Following a single conversion, the LTC2461/LTC2463 automatically power down the converter and can also be configured to power down the reference. When both the ADC and reference are powered down, the supply current is reduced to 200nA.The LTC2461/LTC2463 can sample at 60 conversions per second and, due to the very large oversampling ratio, have extremely relaxed antialiasing requirements. Both include continuous internal offset and fullscale calibration algorithms which are transparent to the user, ensuring accuracy over time and the operating temperature range.Applications System Monitoring Environmental Monitoring Direct Temperature Measurements Instrumentation Data Acquisition Embedded ADC Upgrades

Demonstration circuit DC1555C is intended to demonstrate the performance of the LTC4365 and LTC4365-1 Undervoltage, Overvoltage and Reverse Supply Protection Controllers. The LTC4365/LTC4365-1 protect circuits from input voltages that may be too high, too low or negative. It operates by controlling the gates of two back-to-back connected MOSFETs to keep the output in a safe range. The OV and UV protection levels are adjusted by resistive dividers at the OV and UV pins. Asserting the SHDN pin disables the MOSFETs and places the controller in a low-current shutdown state. The FAULT pin is asserted when the Controller is in shutdown mode or when the input voltage is outside of the UV or OV level.
