Part Number: OPA699 Tool/software: Hi
I am using the opa699 to bulid a comparator A 5kHz square signal from a signal generator is using as the input, but the output's rising edge is very slow, form the waveform it appears that oscillation has occurred…

I am using OPA699 as limiting amplifier after a TIA stage
I wish to use mutiple comparators , arround 6 Nos each with different voltage references
what are the parameters to be considered while interfacing multiple comparators to…
Part Number: OPA699
Greetings TI engineers! I am using an OPA699 for a sweep circuit and am witnessing some unexpected distortion. Here are the facts:
1. Dual supply = +/- 5V. G = +6 with Rf = 750 ohms. No capacitors. Opamp and limit pins bypassed with…
Part Number: OPA699 Hello,
I have some question regarding the OA699 wideband high gain voltage limiting amplifier
1. Is it possible to give differential inputs to OPA699?
2. What is the propagation delay expected from worst case point of view?
3. What…
Hey,
Few suggestions based on your requirements:
OPA843 (800 MHz GBW, 8-12V Total supply, 1000 V/us slew)
OPA699 (1GHz GBW, 5-12V Total supply, 1400 V/us slew)
You can also look at some integrated analog current sense amplifiers here .
Thanks Aditya Go…
Part Number: OPA699 Dear TI Team,
In my application circuit should convert LVDS SPI (10MHZ) signal to single ended signal with variable High and Low voltage levels. Attached is the circuit for your reference. Below are some of my questions.
1. Since the…
Part Number: OPA699 Hi all,
A circuit is being studied to remove minute noise from the input signal using the OPA699 limiter function. When the power supply is +/- 5 V, can both VL and VH be used by applying a positive voltage? For example, in the case…
Part Number: OPA320 Other Parts Discussed in Thread: TINA-TI , OPA699 Tool/software: Hi, I have an OPAMP integrator stage with single supply (VCC=3.3V, VEE=0V). OPAMP is the OPA320.
When I do a simulation with TINA-TI I see a delay time of around 5.2us…
Part Number: OPA699 Other Parts Discussed in Thread: OPA857 , , LMH6629 Hi
What is the clamping circuit of OPA857?
I can see the figure 38 about internal ESD protection.
Is the meaning of clamping circuit is nearly equal to ESD protection circuit?
I just…
Stephen Ziel The power supplies rails are powering the high speed(500Mhz) TIA like OPA699, so your recommendation of increasing input i shall follow, may i keep 2.85V and 5.35 on both Positive and negative rails ?
