Forum Post: TSC2007 - could PENIRQ not be used
Hi Team, Currently my customer has one application question as below about TSC2007 : Could the PENIRQ pin not used, and just leave floating, and MCU just use regular reading TSC2007 for touch signal...

Hi, I understand the requirements should be followed but the requirements about the voltage levels are not clear. Hence my first two questions. Regarding the third question about voltage on/off slope,...

Durmus, Unfortunately, I haven't been able to find the information about the level. But I consider that 120mV shouldn't be an issue, I think that the tolerance should be higher. On the other hand, if...

Hello, I would like to connect the external transducers to the TX-SDK-V2 EVAL board. In order to properly match the transducers to the pulser output (J3 connector), I need to know the output impedance...

Hi Dmitrijs, Impedances: The pulser ( LM96550 ) output on the TX-SDK-V2 board is "loaded" to simulate a transducer. If you like to attach an external transducer, you'd have to remove the "load"...

Hi Hooman, Thank you for your response! Impedances: Since CB51 to CB58 = 330pF & RB0 to RB8 = 2.49kΩ are there only to model the transducer, is there any reason to keep RB0 to RB8 when connecting...

Hi Dmitrijs, Removing shunt resistive load : All LM96550 Electrical Characteristics are with RL= 2kohm. That's the purpose R80 to R88 serve. Having the resistance or not may affect some of the AC...

Hi Hooman, Thank you for this information! Replacing the load with a single series 50Ohm resistor: the reasoning for doing this is that it would be much easier for me to electrically match the external...

Continued investigation shows that, although the DRV2624 seems to properly drive a load >8ohm (per data sheet suggested minimum), elevating the impedance above the 8 ohm mark does not prompt DRV to...

Hi Dmitrijs, I've talked to the LM96550 designer and here is what he said: "The pulser can drive 50 Ohms. It’s just that the swing is reduce because of the output impedance is about 5 Ohms. So the...
