• LTC6362输出温漂问题

    各位好,

           近期使用LTC6362进行单端转差分信号输出,经过高低温考核试验后,发现输出温漂从-40~0℃时约有接近1.几mV,0-125℃过程中,最大温度漂移也差不多有1.几mV。

           整个信号调理电路是通过仪表放大器放大后输出0.2-3.1V的电压,再通过下图的分压电路降低电压至约50mV,之后通过LTC5400和LTC6362进行单端转差分信号的输出。仪表放大器使用的是INA826,电压跟随器使用的是OPA2210,在下图电路POUT处的温度漂移约几百uV,不到1mV。

           输出差分信号通过DEWESOFT进行采集…

    DC1805A uses the LTC6362 fully differential amplifier for a driver. DC1783A uses the LT6350 single-ended to differential driver.

  • RE: AD8137 Output when gain is 1 (unity).

    Hi Hasan,

    I did an experiment with LTC6362

    Note that this is differential input and output voltages. Everything works as it should. You can also conduct an experiment to verify the incorrect behavior of the SPICE model. Simply eliminate all feedback…

  • RE: ADC Driver Low noise for AD7380

    Hi Jocs,

    Here is a list of ADI fully differential amplifiers sorted for low distortion (< -100dB), and low noise (<3nV) as a first pass at zeroing in on suitable drivers for the AD7380 (16 bit, SAR, diff input ADC):

  • LTC2380-24 Figure11b condition

    Hi

    In LTC2380-24 datasheet, 

    Which setting is used in LTC2380? (How ns is acquisition time?)

    With Precision ADC Driver Tool,

    ・ADC Driver is LTC6363(short circuit current is near LTC6362).

    ・fin=2kHz Rext=35.7Ω Cext=6.8nF Sample Rate =2MSPS Vref=5V…

  • RE: AD7380 Analog Input Range

    I just encountered exactly the same issue with the absolute input voltage range that asdf28 ran into.  I was using an LTC2324 driven by an LTC6362 with a common mode input ~1.65V and didn't notice that the AD7380 restricts the absolute input range when…

  • Missing MSB in LTC2292

    Hello,

    I am using an LTC2292 and it seems I'm missing the 12th bit. Here is some background:

    1) I have a differential op-amp (LTC6362) to do a DC conversion from 0V to 2V to +/-1V, with common mode voltage of 1.5V.

    2) I am checking the output of the…
