• LT3082 Set Pin

    I'd like to use the LT3082 in a DAC controlled mode as shown in the typical applications section of the datasheet, but I'd like to do so without the gain stage shown. This should work as the op amp internal to the LT3082 has very high input impedance…

  • LT3082 Set pin open

    Hi

    I'm a DFAE in Japan. Our customer has a question. When the SET pin of LT3082 is disconnected from RSE and CSET, I think the OUT pin is Hi-Z. Is it correct?

    Regards,

    Hiroyuki

  • 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: AD5270 stays in midscale

    The AD5270 is supplied with 5V (provided by a Zener Diode) on VDD and the VSS and GND Pins are connected to the board ground reference(DUT_S), as seen in the schematic below.

    The LT3082 sets a voltage on the output depending on the resistance between…

  • 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…

  • RE: LTC2668 initialization issue

    Here is the schematic.  The SPI lines are usually controlled by another board.  I was doing a "smoke test" before attaching the other board.  I tied CS#/LD to 3.3V to OVP to prevent unintended SPI interaction.  My tech looked and found a solder…

  • 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
