• LTC2449 Data Issue

    Hi All,

    I'm using an LTC2449 for a project that requires a large number of high precision ADCs. I usually prototype chips with an Arduino before migrating them to the full board, but I'm having trouble getting this chip to work properly with an Arduino…

  • LTC2449 Anti-aliasing filter in the MUX/ADC loop

    What constrains the settling time of an RC anti-aliasing filter incorporated into the MUXOUT/ADCIN loop of an LTC2449 when operating in External Serial Clock, 2-wire I/O mode and using multiple channels (i.e. muxing the input)?  From the datasheet, it…

  • LTC2449 reset after data transfer prematurely aborted. CS line permanently tied Low.

    Years ago (2012 and beyond) we began using the LTC2449 as our ADC of choice.

    During development we started noticing data transfer failures. These failures appeared to be tied to "soft resets", someone depressing the CPU reset button, which caused the…

  • RE: Ltc2439-1 in SPI communication data output is high first out or low first out?

    Look at datasheet, LTC2449 is half as noisy as LTC2448, right?So I want to choose LTC2449, ok?

    Thank you very much for your reply!

  • ADuCM360 24-bit Delta Sigma INL Spec

    In the preliminary datasheet for the ADuCM360, it says the ADC's Integral Nonlinearity (INL) at Gain=1 is +/-15 ppm of FSR (same as in the ADuC7060). If I do the math for the number of accurate bits in this worst-case nonlinearity scenario, it comes to…

  • ltc2448 input impedance problem

    Hello all,

    we're using the ltc2448 for our design (see schematic). We're able to control the ADC over SPI and we're also able to receive converted values. These values are somehow plausible.

    But during conversion time we're seeing a voltage…
