  • TL072: -18V TO -12V voltage reference

    Resolved
    Part Number: TL072 Hi team, 1. Here is the circuit which achieve the -18V DC to -12V DC via TL072 and the load is about 10mA. The input and V- is connected to -18V and VDD is connected to the GND. 2. could you help me double check the schematic to…

  • RE: TL072: Does Passive Tone Stack Resistance Get Included in Pole Calculations?

    Resolved
    Hi Kai, At 2:55 in this video, it says the customizable model is embedded in the presentation, but I cannot find it anywhere. I do not think the model in TINA TI is accurate for the TL072 and I want to create one, but I cannot find this generic…

  • TL072: Why the input current increase so much when configure TL072 as comparator

    TI Thinks Resolved
    Part Number: TL072 Other Parts Discussed in Thread: OPA196 Hi, My customer meet one issue when I used TL072. First, when they configure it as amplifier, it works normally. the input current is about 6mA. When they configure TL072 as a comparator…

  • RE: WEBENCH® Tools/TL072: TL072 pre-amp design

    Hi Wilson, Take a look at this circuit cookbook on the non-inverting configuration, it walks through the design steps. Change the parameters to what you need for your system. http://www.ti.com/lit/an/sboa271/sboa271.pdf Thanks, Paul

  • LM2904: LM2904+TL072 stability

    Part Number: LM2904 Other Parts Discussed in Thread: TL072 Hi team, There is a design with the LM2904+TL072 in below. VG1 is a 0 to 15V square wave @732Hz. VM3 is the output but with a 500KHz signal on it as below test waveform. We didn't see…

  • RE: TINA/Spice/TL072: Supply current result of TL072 SPICE model

    Hi Satoshi, Yes this seems to be a bug in the model. There is a resistor connected between positive and negative power supply pins with a value of 2.143kOhm ( Line 32: RP 3 4 21.43E3 ). It should have been 21.43kOhm to produce the right 1.4mA supply…

  • TL072: 10dB increase in noise when using TL072CP vs. TL072IP

    Part Number: TL072 Other Parts Discussed in Thread: TL082 Hello - In a small amplifier circuit I have designed, I am reliably getting 10dB more noise on the FFT when using the TL072CP as opposed to TL072IP. In the data sheet I can only see a few small…

  • TL072: the output of the voltage follower is amplified to the power supply voltage with a zero input

    Resolved
    Part Number: TL072 Greetings, I'm using tl072ip in a voltage follower as a TTL buffer. The chip is powered by a 30V single supply. The output during duty+ periods is correct, but not for duty- period. During duty- periods, the value of the output…
