Other Parts Discussed in Thread: THS4281 , ADS8329 HI
I have aads8329.
this ADC is pseudo diff inputs.
I want connect 200mv to invert input and connect 100mv to REF negative input. how drive or buffer
these inputs?
CAN I BUFFER 100mv,200mv WITH THS4281 …
Hi Sebastian,
Performing a quick calculation, assuming the ADS8860 (16B resolution) device is used in the application, it may be feasible to drive all three ADCs using one REF5045 voltage reference and one composite buffer (OPA333+THS4281) and stay within…
Hi Brian,
I apologize for the delay in the response.
The THS4281 is a high bandwidth amplifier (90MHz), and the maximum voltage across the negative and positive voltage supply is a unipolar 16.5V or bipolar +/- 8.25V.
The amplifier at this node is not…
Other Parts Discussed in Thread: ADS8860 , REF5045 , THS4281 , OPA333 Hello everyone,
I'm designing a three channel ADC conversion using the ADS8860 at a 1MSPS. I would like to use only one reference voltage for all three channels with the REF5045 and the…
Hi Karen,
Missing codes and code saturation are typically associated with excessive variation in the reference voltage during the ADC conversion phase.
A critical component of the reference drive circuit that is missing from your design is the 10uF decoupling…
Hello,
Currently I am using THS4021 in front of DAC900 with one current output terminated to ground with 50E. THS4021 o/p is given to LMH6321 to boost the drive current. Here I am using Boosted supply +/- 15V.
Further I came to know that if from the differential…
Hi Brian,
Thank you for answering.
I am working with below.
https://e2e.ti.com/support/data_converters/precision_data_converters/f/73/t/412866
The application requires low power consumption and OPA350 5.2mA Iq is not acceptable.
Considering a composite…

Hi Mike,
1) As the document explains, the filter cap value is determined by constraining the voltage droop across the capacitor after charge transfer be <= 5% of its initial value. This is a conservative rule of thumb that ensures that the driving op…
HI CWilson,
By changing voltage on pin#10-PKLM you can adjust current limit . To make better noise immunity keep PKLM level 2.5-3.3 V. To "boost" output from Si85xx I am using THS4281. Works good on 250kHz , and gain up to 10.
THS4281 is…
