Part Number: ADS7953 I have ADS7953 and ref4132-3.0v.
The power supply voltage of my system is 5V and the reference voltage is 3.0V.
If the ADC input signal is 4.0 Vpp,
I have problems for these 2 cases
1) 1xVref
Does digital output is full…
Part Number: ADS7954 Other Parts Discussed in Thread: ADS7953 Hi! We're interested to use ADS7954 with our own board. However, in TI's web site we failed to find ADS7954's own EVM, only ADS7953EVM, ADS7957EVM or ADS7961EVM are available. We are wondering…
Other Parts Discussed in Thread: ADS7954 Hello,
I would need an advice for a ADC input filter design. The idea is that I need to design an input filter for ADC ADS7954 . The problem is that I have just one information: Input voltage range is 5V. That…
Other Parts Discussed in Thread: ADS7954 Hi all, Please let us know about this ADS7954. I saw [Figure 59] in the datasheet. I guess, when channel be ON, internal 20M-ohm resistor changes to 200-ohm. Is my guess correct? Regards, Nagai
Other Parts Discussed in Thread: ADS7954 Hi all, Please let us know about ADS7954. We know must have the three voltage inputs for this device. +VA, Vref, and +VBD. Does this device have a power-on sequence? Regards Nagai
Other Parts Discussed in Thread: ADS7954 Hello,
Could you please let me know reccomended pin connections of ADS7954 TSSOP PKG ?
(1) GPIO1~3
Should we pulled up or pulled down these pins? If yes, please let me know recomended resistor value.…
Other Parts Discussed in Thread: ADS7954 Hello,
Please let me know about ADS7954 Manual Channel Sequencing Mode.
Our customer sequence is as below.
Is this sequence correct ?
If no, please let me know this possible cause ?
I see the datasheet…
Other Parts Discussed in Thread: ADS7954 Hello,
In the datasheet P.40 of ADS7954, there the discriptuon about restrinction on source impedance. Could you please let me know maximum source impedance with buffer between the MXO and AINP pins ? Our customer…
Part Number: ADS7945 Other Parts Discussed in Thread: ADS7954 Hi,
I have connected a separate digital supply and a separate analog supply to DVDD and AVDD respectively. The digital supply is always connected to ADS7945 while the analog supply is normally…
Other Parts Discussed in Thread: ADS7955 , ADS7954 Hello,
Could you please let me know the supply current of REFP pin for ADS7954 and ADS7955?
Can I calculate by reference voltage and reference resistance ?
Best Regards,
