Shinichi-san,
I think it would take some time to build up a design, but I don't think this design topology is unique and it could certainly be done with TI components.
First, The ADS7042 would be a good small device to use, but it does not have…
Hello Ryan,
Thank you for your response! Because our system had some hard requirements regarding reference voltage (package size, noise, Iq), we had to go for an LDO option (REF3325-KGD was also investigated but is not preferred by project because of…
Hi Sven,
What is the noise target in uVRMS or the resolution required? We also have the ADS7056 is a 14-B 2.5MSPS ADC available on the X2QFN 1.5x1.5mm package with a thickness of 400um. It is ultra low power consumption, it consumes only 158uW when operated…

Since this part has an open collector output, does it mean…
Hello Pinar,
The reference input to ADS7959 is not internally buffered. The external circuit will be presented a switched cap load.
The worst case switch cap load is expected to be 8.2pF.
If you plan to use resistive divider to generate 2.5V, I will…
Part Number: ADS7952 Other Parts Discussed in Thread: REF3325 , , OPA320 , OPA625 , OPA314 , OPA192 Hello
Intro:
i am designing a board that will have 11 photo-diodes (PD). The PD are connected to transimpedance amplifier (TIA) and the output of TIA is routed…
Hi Chris,
The REF1004I-2.5 is a legacy product. It appears that it didn't have a Spice model developed. That wasn't too unusual for products developed in the arly '90s. If you can consider using one of the newer series 2.5 V references some of…
Other Parts Discussed in Thread: CC2530 , Z-STACK , REF3325 , CC2530EM Hi all,
I'm doing some test with CC2530 and the internal 12-bit ADC but the results are very poor..
I use a very high precision Vref of 2500mV in P0_7 and I do a 12bit conversion as…
