Hi Niels,
I'm only aware of quad FDAs (THS4524: 1.2mA/channel, 490V/us, 145MHz, RR out, ), and not Octal or other arrangement, which is probably your best bet.
For your 14 bit ADC (ADS5294, ENOB= 12.2), the sine wave quantization SNR is:
SQNR =…
Other Parts Discussed in Thread: THS4531 , THS4531A , THS4524 , THS4522 , THS4521 I think there are errors in the spice models for the THS4531, the THS4531A and TH4532.
The THS4531.TSC example (in EXAMPLES\TI Test Circuits) yields an operating current…
OK Greg, here I go again with a new approach based on your suggestions. Please review it and tell me if it is OK or not.
I use a +2.5 V reference for the ADS1274 ADC. The common-mode input voltage of the ADC is 2.5 V, too.
With a reference voltage…
Other Parts Discussed in Thread: THS4524 Hello,
I want to achieve a gain of 2000 using a rail-to-rail output differential op-amp.
op-amp that i have selected is a THS4524. quad configuration.
for 2 opamps i will be using a unity gain. for one opamps…
Other Parts Discussed in Thread: OPA4350 , THS4524 , TPS63061 , TPS63060 does anybody have the footprint for Eagle from this device in DSC package? also for THS4524 in DBT and OPA4350 SOIC(D).
Thanks!
Thanks for the insight!
In my test, there is no input resistors, since both input+ are shorted to ground
The output drives THS4524 (see below)
FYI: the DC-drift is measured at the output of THS4524, but if I short the output of OPA2209, there…
Other Parts Discussed in Thread: THS4524EVM , THS4524 , TINA-TI Questions concerning the THS4524EVM.

Other Parts Discussed in Thread: THS4521 , THS4524 , THS4522 Hi,
I request your suggestion for proper IC selection for very low voltage signal amplification. I am getting a signal (a negative going pulse of about 10ns width and voltage of -3mV) from…
Shuhrat,
Thanks for your patience. I am now back at my desk with all of my reference material and there are a few things that we need to fix.
the formula for hte BW of the amplifier is actually fo * Q * 100. Please note that the 3dB bandwidth term…
Other Parts Discussed in Thread: THS4524 , ADS1274 , OPA2365 , TPS717 Hello,
on a board I am using a TPS71750 (DSE type) in order to power: ADS1274 (75 mA max in high resolution mode), THS4524 (5.2 mA max), OPA2365 (10 mA max) and three accelerometers…
