Part Number: ADS930 Tool/software: Inheriting an old circuit driving an ADS930E.
The ADS930E is powered by +3.3V
VIN- (pin 26) is driven with an external +2.5V reference. An op amp circuit presents a voltage between 2.0V and 3.0V to +IN (pin 27).…
Other Parts Discussed in Thread: ADS930 Hi,
I have a linear CCD module and it is interfaced with ADS930E high speed ADC.
But I am not getting the reliable reading.
For 1V at IN+ pin, ADC digital output is 0 and for 2V at IN+ pin ADC digital output…
Other Parts Discussed in Thread: ADS930 Hi All.
I am in the process of using the ADS930 ADC, and I would like to be able to tristate the digital outputs, or put them in a high impedance state, in order to also be able to write to an LCD screen that…
Part Number: TM4C1294NCPDT Other Parts Discussed in Thread: ADS930 Hi. We are trying to set up TM4C1294NCPDT EPI interface to read data from ADS930.
Example of low speed read:
I set up EPI clock to 20 MHz, which is working fine.
Then I check the…
Hi User5102208,
In the high speed catalog, I am not aware of any ADC or DAC that will fulfill this requirement.
The closest ADC I know of is the ADS930 which is 8-bit, Differential input at 30M.

The closest DAC I know…
Joseph,
Thank you for your very clever idea. I compared ADS932E with ADS930 and ADS931 because these chips have the same packages unlike ADS932. But ADS930 and ADS931 is 8 bit ADC but ADS932E has working pin number 4.
Deu to your information I am…
Couple of quick things Akash,
1. Where is your DC bias current path for the V+ inputs to the op amps?
2. This differential I/O op amp circuit sometimes has a common mode oscillation - probably not here, but we did see that in the OPA838 decomp device…
