Part Number: TS3A227E Other Parts Discussed in Thread: MSP-EXP430G2ET e2e,
I have ordered https://www.ti.com/tool/TS3A227E-EVM for to do evaluation. However, it doesn’t come with MSP-EXP430G2 LaunchPad Rev 1.5 where I’ve ordered MSP-EXP430G2ET as…
Part Number: TS3A227E Hi Sirs, Can we operate the TS3A227E EVM without Launchpad installed? We failed to enable TS3A227E EVM's Mic function with the following process: 1. Applied 3.3V to J1 2. Connected 4-pole cable (male-to-male) from J10 to laptop PC…
Part Number: TS3A227E-EVM Other Parts Discussed in Thread: TS3A227E
Hi Sirs, Would you pls advise: 1. If the DET_TRIGGER# has an internal 1Mohm pull low or pull up. I assume it should be pull low, am I correct? 2. Should reserve a 100kOhm pull up at…
Hi Adam,
That doesn't make any sense because I am using the same audio connector as the TS3A227E-EVM (SJ-43515TS-SMT-TR).
While the TS3A227E-EVM doesn't have the audio codec included, I confirmed it behaves the same as my crude drawings indicate…
Part Number: TPA6166A2 Other Parts Discussed in Thread: TS3A227E Hi Sirs, As title, we have two questions of schematic design of the TPA6166 which need product line's suggestion: 1. Can we leave MOUNT open and connect C3 to GND for Single-Ended mic design…
David,
I think we will need to simulate how the algorithm will behave when it sees 3.3 V on SLEEVE and GND on RING2. This can take some time with the design team. I think the fastest approach is to get a TS3A227E-EVM and just try it and see how the…

Yusuke-san,
The audio jack you show does not contain a switch that can be used to trigger a detection sequence. You will need to select on that has a switch like shown in the TS3A227E EVM if you want to make use the insertion of an audio accessory triggering…
Other Parts Discussed in Thread: TS3A227E Question on behalf of customer:
So far, I can control the TS3A227E EVM board and the basic function is work.
But I still have two questions about the TIP pin and switch. Could you help to clarify it?
…
Peter,
I have asked our team about obtaining this characterization data. Unfortunately, when this part was designed this use case was not thought about and the off state capacitance of the switches was not characterized.
We are looking into a test…
