Part Number: OPA699
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…
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…
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 ?
TIA is Transimpedance amplifier
LA is limiting Amplifier
The chasis ground is connected to mouting holes for external ground lug, AGND is TIA + LA + Comparator GND, and Power ground is for DCDC and LDO.
I star connect these ground together.
A 10nS pulse…
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…
Other Parts Discussed in Thread: OPA699 one of my design involves pulse signal processing from photodiode, i am using OPA699 as a limiting amplifier stage before to comparator and next to preamplifier, current gain i have set for OPA699 is 10 using 680…
