Part Number: OPA838 Other Parts Discussed in Thread: OPA855 , OPA695 Tool/software: TI C/C++ Compiler My source signal is 5mv, 5ns pulse signal.I want to amplify it by gain 100V/V. What amplifier I can use? Is there any reference circuit can solve my problem…
Part Number: OPA838 Other Parts Discussed in Thread: OPA4354 Hello TI.
I'm simulating with the OPA838 amplifier in a single supply design. The Bias current does not match the datasheet. I have created a design where the absolute voltage in relation to…
Part Number: OPA838 Other Parts Discussed in Thread: TINA-TI Tool/software: TINA-TI or Spice Models I tried to use the OPA838 with LTspice :-P, however the TINA SPICE model has occrred a floating error at GRA and GRC node.
I have solved this error to modify…
Part Number: OPA838 Other Parts Discussed in Thread: TINA-TI , Tool/software: TINA-TI or Spice Models Hello,
My colleague is trying to use the OPA838 with OrCAD Capture, but the TINA model does not seem to be compatible. It is comprised of many .subckt…
Part Number: OPA838 Other Parts Discussed in Thread: OPA354 What is the maximum dual supply rating for the part? It appears to be 5.5v/2=2.75v so the part cannot be operated with anything greater than +2.75v to -2.75v. Is this true? I was hoping to operate…
Part Number: OPA838 Other Parts Discussed in Thread: OPA615 , TINA-TI Hi - I have a signal that varies between 2MHz and 30MHz and can also vary in amplitude between 100mV peak to peak and 1000mV peak to peak. I'm attempting to count pulses using a counter…
Hello Peter,
At TI we cannot provide tested models or support debugging LTSpice software. Our best recommendation is to take the PSPICE model and import the netlist into LTSPICE: this does not always create a complete working model but may work well enough…
Part Number: OPA838 Other Parts Discussed in Thread: TLV3541
Hi,
I'm using TI's op-amps (OPA838 7V/V + TLV3541 1.3V/V) as two-stage amplifier for a current signal. The schematic is shown as following. The amplified signal goes to a MAX comparator.…
Thanks Evan.
On the external amplification , can I use OPA838IDBVT or you have any other recommendations?

Part Number: OPA836 Other Parts Discussed in Thread: OPA838 , , OPA837 Hi team,
My customer is using our OPA836 & OPA838 now.
And they wonder if we have a newer device to recommend.
Requirements:
BW: >200MHz
slew rate:>200V/us
Iq:<1mA
Thanks…
