Unknown Neve Module

Hi Team,

I came across these modules and got no clue what these actually are:

[EDIT: PICS REMOVED]

Got them off an old A/D card. Hope some can help me.

Thanks,

Sure looks like a DOA type footprint, huh?

That was my first thought too. Will retrace the host PCB soon to identify the pin out.

If it's from an old A/D card then I can imagine that it might be an A/D converter or related to it. The Neve company was actually pioneering in the early days of digital audio, which is probably very much forgotten nowadays.

Didn't find the time to retrace the pin out yet.

But I doubt this part is digital-related due to the low pin count.
The digital and logic ICs on the board are mainly DIP20 and above.
Mostly manufactured by Analog Devices.

Maybe Geoff Tanner will know the answer?

Maybe a 20khz filter?

You may have a voltage to frequency converter, an early but slow way to digitize analog, useful for volt meters. The two pins on one side would be analog in and analog ground, the other five would be +/-, dig ground, osc output, and offset.

I have a similar one here, a BB VFC12, 1mV in=1hz, so 1V=1Khz, 7V=7Khz, like that.

Ahh, found it, different form factor, but see if it seems to make sense in the circuit:
