Currently, the main problem is that the first valid data value after decoding with 8 pieces of chips fluctuates, and the 8 pieces cannot guarantee that the first valid data is the same, which will cause deviations in the subsequent data, as shown in the following figure. We have used trig before each link establishment and performed the synchronization operation on the 8 pieces. ...https://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095031/tca9535-tca9535pwr---lead-color-change-observed-after-reflow-soldering/3943074Mon, 21 Sep 2026 00:13:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:52f9cdff-29c9-4e56-9844-6c453368e286Alice[quote userid="122283" url="~/support/data-converters/f/data-converters-forum/1095031/tca9535-tca9535pwr---lead-color-change-observed-after-reflow-soldering/3942270"]E2E技术论坛旨在解决客户在使用TI产品过程中遇到的技术问题。 如有更多疑问，建议您请按照以下方式联系客户支持部门，会有客服为您提供帮助。 www.ti.com/.../customer-support.html [/quote]https://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095488/amc60804t/3943068Sun, 20 Sep 2026 23:41:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:07d9735c-842a-4039-8e2c-104fc9184549Eirwen请通过下面链接申请： www.ti.com/.../AMC60804-DESIGNhttps://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095488/amc60804t/3943063Sun, 20 Sep 2026 23:12:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:fd98b70d-c5d2-451c-9ae5-37462e40fff3Eirwen已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095279/afe4403-ppg-21-21/3943062Sun, 20 Sep 2026 23:10:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:8cbb4bfd-deea-4ccf-9585-a7d455ed8308Eirwen已经收到了您的案例，调查需要些时间，感谢您的耐心等待。https://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095031/tca9535-tca9535pwr---lead-color-change-observed-after-reflow-soldering/3943042Sun, 20 Sep 2026 05:08:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:5581f0ee-fc58-4b32-9fb6-54d023e5f4f8user4727740工艺参数已经确定按照规格书要求来的，想确认下，这颗器件过回流焊后，PIN脚颜色变化，是否正常？https://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095488/amc60804tSun, 20 Sep 2026 03:14:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:824f6417-47ff-4408-9bb8-e6447b0d9e46l aPart Number: AMC60804T 希望获得完整规格书,以便选型AMC60804Thttps://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095279/afe4403-ppg-21-21Fri, 18 Sep 2026 10:19:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:c2132369-8d37-403d-b2c5-75b1f042ddcdwang chaoPart Number: AFE4403 如图，参考最上面的一条曲线，有明显噪声，占空比为22%，下面这幅图占空比为21%，无噪声。可穿戴设备（非医用）AFE4403https://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095269/ads4149-ads4149-vcm-0-95v/3942385Fri, 18 Sep 2026 07:07:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:cc41906b-ea2c-49ed-a426-f9089bca812dDaniel您好 这个值是在上述条件下测得的，并给出如图参考，所以排除损坏的情况下，应该在0.95左右。https://e2echina.ti.com/support/data-converters/f/data-converters-forum/1095269/ads4149-ads4149-vcm-0-95vFri, 18 Sep 2026 06:46:00 GMT91561404-af28-475a-b96b-cb6cbaadd097:b5218a3a-1642-44ee-892b-28b0a15b5241shi zhenguoPart Number: ADS4149 Each circuit board incorporates two ADS4149 chips. We have manufactured several such board prototypes: on some boards, one of the two ADS4149 chips has a VCM output voltage of 0.95 V, while the other chip's VCM output is 0 V; on other boards, the VCM output voltage for both chips is 0 V. I would like to know whether the VCM state of the ADS4149 chips is random upon power-up. I have attached the schematic diagram; could you help me determine the cause of this behavior? Thank you.
