alternative to AD8608 op amp for active filter design - ADAU1701
Hi all, I've been looking to implement an active reconstruction filter on the DAC output of my custom ADAU1701 however the op-amp recommended in the datasheet seems to be end of life and highly priced

Adau1701 dac output passive vs active.
Hi guys, I'm not sure which type of adau1701 output I should use (Passive vs Active), what are the advantages of one over the other, not to mention the cost? When using AD8608 or another operational a

ADAU1361 differential amplifier not working, no internal bias on input pins - damaged part, or just misconfigured?
I'm bringing up a new design that utilizes an ADAU1361, and I've run into a bit of a snag that I'm hoping is just due to a misconfiguration of the device, but which I fear is actually evidence that th

DC coupled input on ADAU1761
Hello there, is it possible to use a DC coupled input on the ADAU1761 in a single-ended input configuration? Specifically the line input pins LINP, LINNP, RINP, RINNP ? I'd like to be able to measure

EVAL-ADAU1761Z - interfacing with an electret microphone - CCPL input needed
Hello, For my project (active noise control in an experimental rocket), I'm planning to use this microphone : http://www.bksv.fr/doc/bp2055.pdf It needs a CCPL supply (2 to 20mA, 24 to 30V) to work. M

need to use the bias voltage for the differential inputs adau1761?
I am designing a mic mixer project that will be connected to the output from a wireless recieved (balanced xlr). do i need the circuitry used o the evaluation board, and do i need to use the BIAS volt

Bias Voltage from an ADAU1701
I'm sure this is a simple question, but is there an easy way to supply a bias voltage to a mic input on the 1701? I was using the 1761 previously, and it provided it for me... Thanks! --> freddie Audi
