FAQ
Hi,
I am using the ADA4899-1YCPZ.
I would like to know if it can be used with an asymmetric power supply +7/-2.5V.
In such case, should the EP be connected to Gnd [0V] or to VEE [-2.5V]?
Best Regards
Alfonso
Hello,
I am using ADA4899 as fully differential ADC driver with gain = 5.
I am simulating this circuit in LTSpice. When I leave the "disable pin floating", i see a total noise of my circuit as 89.057nV/rtHz. When I connect the "disable pin to the positive…
Could the power supply of ADA4899-1 be ±2.5V? Thanks!
The SOIC version of ADA4899-1 has two '-Vs' pins, I wonder if I can only use pin 5 and leave pin just floating, will this degrade the performance of it?
Thanks.
读ADA4899-1的datasheet,输入端有二极管保护,而Absolute maximum ratings里面,说输入差分电压是±1.2V,这种情况还需要在外部加限压吗?应该是靠内部二极管保护就可以了吧?输入脉冲电压,幅度随机,一般在1V以内,少数可能达到3V以上。±3.3V供电。偶尔出现运放失效的情况。
