Thank you for your reply.
Could you teach me about the maximum junction temperature of AD820 ?
This is not described in the datasheet.
Alomost all of parts is desribed as 150 degree celcius but AD820 is not descibed.
So , our customer…
I'm using the AD820 in a loop filter in an RF circuit and I would like to maximize the ground plane area. Can the "NC" pins on the AD820 (SOIC-8) be grounded without ill effects? I am also using the ADP151 voltage regulator. Since the datasheet for the…
What is the input impedance (ohm||pF) of the AD8627?
I'm using the AD820 now but I would like to find alternative parts. The AD820 data sheet shows imput impedance spec
but AD8627 does not.
I think that AD820 spice model does not include temperature charachtristcs.
Is it correct ?
Our customer uses AD820 spice simulation (using LTspice)
but the current consumption in simulation result is 2ma@ 25 degree celcius and ~9mA @ 85 degree…
The plus and minus inputs on the second AD820 are swapped. See figure 50
on the AD8510 datasheet for a correct schematic.
it is allowed to view simplified schematic of op amps AD711 and AD820
what is inside in outline
HMC703 vco use HMC531 in the library
pfd 50M out frequency 12.8~14.2G
Question1:whatever parameter(loop filter) i choose, i can't lock to 10Hz,unless i choose lock to single frequency
Question2:i choose different OPA ,like AD820 it can lock to…
