  • LMH6624: LM6624MAX/NOPB

    TI Thinks Resolved
    Part Number: LMH6624 Hello, This is Jeon from SEMITECH CO.,LTD I have bought LMH6624MAX/NOPB .2500pcs 44pcs of 2500pcs are not working. the ultrasonic value of the part is down and it does not work. you know the stanard value is 3Volit but 44pcs is…

  • RE: TINA/Spice/LMH6624: TINA TI

    Hi Stefan, if you power the LMH6624 with a single supply voltage, you need to set a DC operating point like shown in figure 56 of datasheet. Kai

  • LMH6624: Can it be used in the place of instrument amplifiers

    TI Thinks Resolved
    Part Number: LMH6624 Other Parts Discussed in Thread: ADS9110 , LMH6551 Hi, Can this chip be used in the place of instrument amplifiers? Saw on the datasheet it can be used for instrumentation sense amplifiers. Instrument amplifiers I am seeing have…

  • RE: LMH6624: Stability at Av <10

    Hi Jonathan, thanks for reaching out. I try to understand your stability problem but can you please provide more information: - what is the DAC's output for the op amp? - do you want to use an inverting configuration by saying "resistor in series…

  • LMH6624 spurious anomalies

    Other Parts Discussed in Thread: LMH6624 I am using the LMH6624 in a high gain, non-inverting configuration with a gain of 51 (Rf = 499 Ohms, inverting input to ground resistor = 10 Ohms). Layout guidelines have been followed with ample ground plane in…

  • RE: LMH6624 unexpected frequency response (peak at 250 MHz)

    Resolved
    First, thanks a lot for answering. Before I go deep into them, I will just make some short comments. 1. The Cpd is roughly 40 pF. The PD is biased at 5V 2. Is it possible to simulate myself or get that Aol information from the LMH6624? I checked…

  • ultrasound (piezoelectric sensor) preamplifier using LMH6624

    Other Parts Discussed in Thread: LMH6624 I try to use LMH6624 to make a prea-amp for a piezoelectric sensor. I chose it for the wide band and low noise characteristics. I tried to use it in a traditional circuit where imput resistor is 1M or higher. Due…
