  • THS4222: THS4222 Issue

    TI Thinks Resolved
    Part Number: THS4222 Other Parts Discussed in Thread: TLC074 , OPA2690 , OPA2890 Hi, I need support about a simple circuit involving THS4222. Attached you can see the circuit. The input signal is a sinewave 3Vp 50Hz (0 offset), the output signal shows…

  • RE: THS4222: Output's Rising time and delay time question during high temp condition

    Hello Paul, Are you still observing the output rise time & delay time extensions during high temperature? I can assist with recommending a different package type or high-speed op-amp. I did notice the use of the LMH6643 IC on the schematic you sent…

  • THS4222: PowerPad connection when Dual Supply is used

    Resolved
    Part Number: THS4222 Good morning, in some of my circuits I've aready used your High Speed Dual OpAmp THS4222 in 8VSSOP package (THS4222DGK, Without PowerPad) and I'm very interested in continuing to use it. I need now to switch, for power dissipation…

  • THS4222: Maximum quiescent current

    Resolved
    Other Parts Discussed in Thread: THS4222 Hi TI community, sorry to bother you with a most probably stupid question, but I am a bit confused now. I am using the THS4222 with a +/-5V supply. Looking at the measured quiescent current I can see approx. 28mA…

  • THS4222 gain performance.

    Other Parts Discussed in Thread: THS4222 , OPA2690 , OPA2691 Hi TI technical Support, Please find the figure below. Here i am confusing with first parameter. In small signal bandwidth: test conditions it is showing that G=1,Pin = -7dBm. what is this mean…

  • RE: SN10502: About current consumption specifications

    Well the TSC you inserted is using an encrypted op amp model and is locked - can't do much with that, but looking at it - that 100uF capacitance may be causing a self oscillation in the input stages - try putting 100ohm in series with each V+ input. Also…

  • RE: AD828 vs 826 EMG

    Resolved
    Hello Mike, You state the AD828 in the SUBJ and the AD A 828 in the text, and both of these are Analog Device parts, therefore, we cannot comment on the usage. If you wish to do a design with a similar/better TI device, please look at the THS4222 or the …
