• RE: LT3082 Set Pin

    The gain stage is needed in this circuit because the chosen DAC doesn't have the required voltage range.  If your DAC can reach the highest desired VOUT voltage, you don't need any amplification.

    Another issue I ran into is the LT3082 doesn't tolerate…

  • RE: 最近需要一款0-3.3V输入,4-20mA输出,3.3V或5V或12V供电的芯片,有什么好推荐的吗

    我想你應該是指定電流輸出吧???

    如果試的話  可以參考這顆LT3082 Datasheet and Product Info | Analog Devices

    或者是一般的linear type LED Driver

    在如果你是要定電壓  但輸出要有4-20mA 的話

    其實挑ADP12X 系列就很夠用了

  • RE: LT3090 output voltage controlled by DAC

    The image below shows the basic concept of how to control an LDO output using a DAC.  The LT3082 in the image is a positive LDO and the LT3090 that you want to use is a negative LDO, but it should still be possible to drive the LT3090 SET pin in a similar fashion…

  • LT3080 Dropout Voltage

    A customer asks concerning the LT3080:  "We operate at: Vin = 3.3V Vout = 3V, Vcontrol = 5V, output current max. = 200mA. Is this ok?"

    This is a common question so I will answer it myself in a REPLY post.

  • LT3080 Exposed Pad Is Soldered to Ground by Mistake

    I get this question frequently so I will post the question and then answer myself:

    "I made a mistake and did not notice that the LT3080 datasheet says for the DD PACKAGE that "EXPOSED PAD (PIN 9) IS OUT, MUST BE SOLDERED TO PCB".  I made…
