• LTC2485/LTC2487 - How to stop a conversion or prevent a conversion from starting.

    I am using both the LTC2485 and LTC2487 in an application. 

    When my I2C bus finishes reading the results of a conversion, a new conversion automatically starts.  This locks me out from writing a new conversion configuration for upwards of 150 mS.

  • LTC2485: can it be used for shunt high side measurement?

    Hello,

    I would like to use the LTC2485 for directly measuring a high side shunt voltage for measuring a highly dynamic current.

    The shunt resistance will be 30 ohms and the voltage after the shunt will be regulated (to compensate for the shunt variable…

  • LTC2485 reference circuit

    The data sheet (page 32) of the LTC2485 includes a reference circuit for thermocouple measurement, which can also be found here:  Solutions - LTC2485 Complete Type K Thermocouple Measurement System (I2C) with Cold Junction Compensation 

    The description…

  • RE: Selecting and ADC for weigh scale

    I just realized this can't work with the LTC2485, because while IN+ - IN- will be 20mV, the common mode voltage will be 5V, which is outside the specs of the LTC2485 when powered by 3.3V, so I will have to use an I2C level shifter after all.

  • Circuit Design for Low Current [nA] & Low Voltage [uV] Precise/Accurate Measurement.

    Hello everyone,

    Can you please suggest set of 24 Bit high speed ADCs & DAC for low current & voltage measurement. I want precise & fast ADC for measuring current in nano Amperes (nA) & voltage in micro Volt (uV).

    Necessary speed for data…

  • RE: EasySMU and Firmware for DC2591A

    Hi NoahC,

    Unfortunately the engineers that worked on this project are long gone, so a few of us that were around when it was designed are in sustaining mode on. While the hardware design is considered robust, the firmware relies on libraries provided by…

  • LTC2453 Reference voltage input range

    We are using the LTC2453 to directly read a sensor. In our applcation the specified minimum reference voltage of 2.5 is not ideal. Is it feasible to use this ADC with lower voltages lets say 1 to 2V?

    I'am asking since the datasheet of the LTC2485 explicitly…
