Dear all,
Our customer is studying BUF16821-Q1 now.
I have gotten some questions regarding BUF16821-Q1 from the customer.
So please teach me about it.
1. Is the LPF which is composed of resistors and capacitors necessary?
In the circuit diagram of Figure 19. "Typical Application Configuration" of the datasheet, there are RC LPF circuits which are at DAC output terminals (OUT1 ~ 16, VCOM1, 2).
Aren't these LPFs used for compensation of phase margin?
In the case that there is no LPF at DAC output terminals, Is it no problem?
2. If these LPFs are necessary, please teach me the recommended value of resistors and capacitors.
I know that the capacitors must be less than 220 pF.
3. If there is no LPF on DAC output terminals, is there any possibility that the output signals on these terminals oscillates?
Best regards,
M. Tachibana
