Please refer to the timing diagram on Page 5 under Timing Specifications on the Datasheet.
Hope this helps.
I have two questions about the output inductors for the ADA4961.
1) According to the ADA4961 datasheet, the recommended output inductors are Coilcraft 0805CS-471XJLC. The reason given in the datasheet is: "The self resonant frequency of these…
What is logic level needed on PWUP pin 19 to enable the ADA4961? I am operating at 3.3V, low performance (PM= Low).
The logic levels for the SPI bus and ATTEN controls are defined VHIGH= 1.4V min. Does this include the PWUP pin as well?
On p. 21 of the datasheet, the Coilcraft 0805CS-471 470nH inductor was recommended as the output chokes for the ADA4961. We found that using these chokes caused a 1-dB drop in gain around 1GHz due to their internal parasitics. I suggest either the Coilcraft…
I am looking to do a simulation of the ADA4961 input driver circuitry using a SPICE simulation tool.
I am only able to find the S parameters for the ADA4961 on the ADI website.
I unfortunately do not have access to any software packages that…
Is it ok to operate the ADA4961 with a supply between the 3.3 volts and 5 volts quoted in the data sheet ( say 4.5 volts)?
My assumption is that the performance will then be somewhere between the specs quoted for 3.3 volts and 5 volt operation - is this…
For ADA4961, the datasheet shows the curve above 10MHz, and I wonder the spec between 10MHz and 1MHz, whether or not the performance will decline between 10MHz and 1MHz.
My requirement is that one amplifier covers 1MHz to 600MHz, with…
I'm looking to use an ADA4961 to drive an AD9255.
CN-0279 provides a design procedure for using a BPF which seems to target amplifiers with a higher output impedance (the note suggests 200 to 400 ohms) so I want to sanity check the approach when using…
What should be done with A1, A0 and LATCH inputs on the ADA4961 when using the serial interface? Should they be open, grounded, pulled high/low?
I have the ADA4961 evaluation board EV-ADA4961SDP1Z and it is not working even though the SPI interface software seems to work all right.
There is an instruction to load the eeprom file ADA4961_eval_board.sdpeeprom, but it was not included in the software…
