    Ravindra, There are examples of output filters in the EVM User's Guides if the information in the datasheet is not enough. The TAS5630DKD2 has a good example for the TAS5630. The recommended inductor is a 7uH/5A (30 mR) Low THD+N Ferrite Inductor. Take a look at the Fe-Tronic TIC-INDC-026....

    Brian Burk
    Ravindra, Driving a transformer should work as I've seen other applications of this. The main concern is during no-load, what is the inductance of the transformer? You don't want to send the part into over-current protection. When loaded it should not be a problem as long as the impedance...

    lalonde charles, Officially, the manufacturer (TI) does not guarantee any device specs outside of the noted operating temperature range. Unofficially, many devices will operate just fine at operating temperatures outside of the specified range. Specs that typically change at high temperatures include...

    The data sheet says 25 - 52.56V but it doesn't look like PVDD is monitored for under voltage only VDD. Will the TAS5630 function with less than 25V.

    Hi, there have been already 2 posts relating the usage of this IC in a low-freq or even DC application, still I'd like to elaborate on the problem as the IC does not work how I expect it to. In my application, I need to amplify analog inputs (between 0 and 10kHz) to the level of about 50V...

    My application for the TAS5630 is as a DC input amplifier with a bandwidth up to 10Khz for a field cancellation controller. In order to evaluate the TAS5630 IC for this application, I am testing one channel of the TAS5630DKD2EVM module with the following conditions: Using only the right channel. The...

    Hi Don, Thanks for your quick response. Our application is for an improved version of our magnetic field cancellation controller that suppresses the fields within a confined space by opposing the magnetic field with external coils. For this application, we need class D amplifiers with analog DC...

  • Forum Post: Re: TAS5630 OSC pin inputs

    SteveCrump
    I think you will want to drive OSC+/- differentially for best audio quality, avoiding edge contamination as much as possible. There may be some timing considerations here. I will check and let you know. Best regards, Steve Crump.

  • Forum Post: Re: TAS5630 OSC pin inputs

    SteveCrump
    In a modular system like yours I would absolutely discourage single-ended clocking. I believe a differential system is required. As long as the entire transmission system is differential and skew is small, like the 100pS you cited, your approach should work fine. Best regards, Steve.

    Generally the switching frequency for analog-input devices in TI's TAS56xx family ( TAS5611 , TAS5613 , TAS5615 , TAS5630 ) is controlled by a single resistor. It is also possible to use an external clock. Each device includes a master clock oscillator, and its frequency can be trimmed with a...

    A customer named John E. asked the following question outside the forum. Can you tell me the current consumption of the 12V pins (VDD and GVDD) for the TAS5630 class-D amp? I’m designing a board and need to figure in the power consumption of the 12Vdc supply. I couldn’t find that specification...

  • Forum Post: Re: TAS5630 Ivdd+Igvdd

    SteveCrump
    John, there is some complication to determing the value you want. I.vdd and I.gvdd can be found in the data sheet, but a little computation is required to get the total. See page 10 of the data sheet SLES220B for the individual values. Total 12V supply current is I.vdd + 4 * I.gvdd or about 73mA nominal...

    Aubrey, I will try to help with this. As Don explained, we didn't develop TAS5630 for DC operation, so we haven't characterized it for that and aren't certain what is required. However, I'll try to suggest some paths to a solution. First, is it possible to provide a slow start for...

    SteveCrump
    Tomasz, the first series, WE-HCC, may be able to work, but only if you reduce the OCP current level by increasing the resistance at OC_ADJ. Making the resistance 36.5k will lower the OCP level to about 10A. (Note that this is as low as this level can be set. Reducing the resistance more simply shifts...

    Masa, I have puzzled about what caused this. I do not see why it should be the transformer load, so I think maybe it is the input signal. Can you capture the input signal as you turned it on the second time? Connect it to the EVM as before, and repeat the turn on a few times and capture it each time...
