Update on this - it turns out the PID tuning is critical here. I used the Matlab system identification tool to use the above response data to estimate the plant model, and then the PID tuner app to compute the PID constants. After applying them to my…
您好：
我是ADN8831的用户，最近在调试时发现以下问题，亟待您的技术支持：
1.在控制TEC温度中，稳定时间有点长，调整P参数后，变得不稳定；
2.制热状态时，OUT1输出能够和温度设定电压跟随，但在制冷模式时，OUT1和温度设定电压差很大，长时间不能锁定
3.在上述2描述的状态中，TEC的温度确是能够正常体现的？
电路设计，参数配置，我们参考的ADN8831评估板（AN-695）
亟待您的解决方案，望尽快回复！

Hello,
i'm trying to understand the typical application circuit in ADN8831 and i've got a couple questions and i've got a couple questions.
1) It says that the soft start is set with a capacitor connected from SS (pin 14) to ground, but…
Where are the AGND and PGND tied on the ADN8831 eval board?
It looks to me like the eval board has everything separated on the top layer and then going to one solid ground on Layer 2. If so, the analog and power ground symbols on the eval board schematic…
Hi,
I'm having problems getting the ADN8831 to work. My design intent is to have three of drivers controlling 3 separate thermal bodies. My schematic is attached - although it shows the P channel FETs mirrored and i've actually corrected this and…
Hello. Help solve the problem, with a thermoelectric controller ADN8831 used in an 695. Tell me the formula to determine the unknowns R1, R2, R3 for given values of the variables R(mid) R(low) R(high) to adjust the desired temperature range 0 - 6 C.…
I would like to ask about the current that can flow to the TEC when using the ADN 8831.
# 1 Selection table has Iout = 4 A, but where do you see the rules if you look at the datasheet?
# 2 If there is not it in the datasheet, is there any data…
I have a question to the TEC controller chip.
My laser diode output depends on the temperature.
So, using the TEC controller chip, i want to maintain the temperature automatically when the laser output is 1W.
In other words, the laser…
