Hi Jason and welcome to E2E,
There is a pad layout description on page 45 of the OPA4322 datasheet found here www.ti.com/.../opa4322.pdf .
You may have to make your own pad for this one.
Best regards,
Sean
Other Parts Discussed in Thread: OPA4322 , PGA411-Q1 Hello TI,
I have project about EV motor control need you help or suggest suitable TI Design.
Our The 3-phase PMSM spec is power rating 13 KW, 130 N.m, 6000 r/min. Battery Pack Voltage 144VDC.

Leo, OPA4388 will NOT be fast enough to settle to within 16-bit resolution at 1Msps sampling rate. If you use the op amp in an inverting configuration, please take a look at OPA4350 (GBW of 38MHz) while for the non-inverting configuration you should use…
Hi Aj,
what do we see on the scope plots? Is it uncorrelated noise? Or is it the 300kHz signal from the ultra sonic sensor?
The OPAmps: Is it the OPA2322 or OPA4322?

Hi Jacob,
you violate the common mode input voltage range of LM2901. This chip can only handle input voltages which don't exceed 3.3V-1.5V=1.8V. But the OPA4322 gives out up to 3.2V! You might need a comparator which can input rail to rail.
Ka…
Hi Mark,
Q1: The UAF42 datasheet specifies under "Filter Performance" that the frequency range, 'fn' is typically from 0 to 100 kHz. Does this mean that if the high-pass filter cutoff frequency is set to 20 kHz, that the pass-band will…
Hi Ronald,
Whats a pity, the maximum supply voltage in some corner case would be 6V, but OPA4322's maximum supply voltage is only 5.5V, could you help to recommended one amplifier with higher than 6V supply voltage? And its VoL should be as low as…
Hi Frank, First of all, I apologize for the issues you've run into. As you've seen, we've attempted to partially rectify the situation by adding an appropriate voltage reference circuit and notes about the problems with the controlCARD in the infosheet…
Hello,
In that case, I do not know where the oscillations in my signal chain could be coming from. Could I share the schematic with you offline? We are using two TI amps: LMV861 and OPA4322.
Other Parts Discussed in Thread: OPA4322 Hello,
An OPA2322AIDR is being using in the attached schematic as a charge amplifier for a piezoelectric receiver array.
With the following parameters:
Input 50ohm-terminated to ground (i.e. no signal input)
