Part Number: OPA350
I use an OPA350 to buffer the ADC's unbuffered voltage output (VCOM). The ADC's VCOM pin provides a voltage output equal to AVDD/2 to set the output common-mode level of the analog input drivers - in this case, 8 differential amplifiers…
Hi Herman,
thank you for your answer it initiated the solution. I have read the manual further and there is PSPICE compatibility mode. I use ngspice 3.0 and setting the compatibility mode fully solve the issue. Your PSPICE .lib files run without issue…
Part Number: OPA350 Other Parts Discussed in Thread: LM7705 Hello,
The OPA350 datasheet says the Voltage Output Swing from Rail is 10 mV Typical, 50 mV Max @ 10kOhm.
With the same opamp output impedance and 10 times lower current, shall we expect…
Part Number: OPA350 Other Parts Discussed in Thread: TINA-TI , I made a mistake in a circuit design and ended up with results I am struggling to understand. It seems there is about 50 ohms from the output pin to ground. Is this number stated anywhere…
Part Number: OPA350 Other Parts Discussed in Thread: TINA-TI , , OPA171 Tool/software: TINA-TI or Spice Models Hi,
I am trying to use the OPA350 SPICE model into Altium Pspice Simulation, but I am getting lots of errors from the OPA350 PSPICE model…
Other Parts Discussed in Thread: OPA350 , PCM4202 , OPA1632 , LM833 When i use the OPA350 in non inverting configuration with Rg = 2k7 and Rf = 1M
when i feed 5mV to the positive Input via Frequency Generator i Need to set an
DC Offset of 2,5mV to…
Other Parts Discussed in Thread: OPA350 , TINA-TI Hello,
I am designing power electronics converter in which I will measure the DC capacitor voltage. As an isolated voltage sensor, I will use ACPL-C87X from Avago. This IC needs a post amplifier to combine…
Other Parts Discussed in Thread: OPA350 Hi,
In order to make a lowcost circuit, i used Application report SBEA001, in partilcular the laserdiode driver - 1.
but instead of using vcc of OPA350 at the same voltage of transistor, i tried a variant schematic…
Hi Yiyang,
Welcome to the TI E2E Forums!
I do not see any issues with what you are proposing! The OPA350 can certainly drive this capacitive load. Additionally, giving each ADS1255 its own reference filter will prevent transient current from one ADC…
Other Parts Discussed in Thread: OPA350 , ADS1278 , THS4521 , OPA2188 Hello,
In the datasheet for the THS4521, there's an application circuit showing it driving a ADS1278 ADC. In that circuit, OPA350 is being used to buffer the common mode output from…
