about ADA2200

Question

Hello. 
 
 I am working for the development of biomedical device. 
 
 To deal with the signal, we are considering lock-in amplifier. 
 
 To make circuit for it, we are considering AD630/ADA2200 IC. 
 
 In case of the AD630, there is price problem.(relatively expensive) 
 
 So we want to apply ADA2200 but the official website show me that it will be discontinued. 
 
 So, please recommend similar IC with ADA2200. 
 
 Thank you 
 best regard.

Hi Mr.KANG , 
 Did you find this article already ? 
 https://www.analog.com/en/analog-dialogue/articles/synchronous-detectors-facilitate-precision.html 
 It shows how you can build such an lock-in amplifier based on AD4077 precision amplifier and a few components around it if the AD630 is too expensive.)
