Hello Sean,
I do recommend working with the OPA891 and OPA810. The OPA891 is a part of our family of high-voltage, low noise op-amps.
We also have the OPA2891 if you require a dual-channel amplifier. Thank you for trying and testing the method I recommended…
Part Number: LMH6611 Other Parts Discussed in Thread: THS3491 , OPA2675 , OPA891 Tool/software: Hi team,
Do we have higher current amplifier but with similar spec with LMH6611 ? LMH6611's 100mA drive current is not enough.
Hello Jerry,
From above spec table, the LMH6611 should still be able to obtain 2.0V if power supplies are set to +/-2.5V. As a quick test to eliminate current/load dependence, set the load resistor from scope to high impedance. Impedance matching shouldn…
Part Number: LMH6611 Other Parts Discussed in Thread: OPA810 , TINA-TI I want to simulate a circuit which is showed in the TI's document :SLUUC92. The amplifier LMH6611 and mosfet SIS412DN-T1-GE3 are used by the circuit.
But when I simulate this circuit…
Hey Brad,
The LMH6611 isn't being limited by slew rate here, the plot looks more like an RC response... Recommending a different amplifier wouldn't be helpful without finding the cause of the issue first. Outside of disconnecting the sink device, can…
Part Number: LMH6611 Figure 67 appears to be wrong; the parts I have are behaving as if there is only one back-to-back diode combination, and not two. In shutdown I have approximately 0.8V across the inputs, and am drawing about 10mA. Can you verify this…
Part Number: LMH6611 In one of our projects an LMH6611MK will have to drive a capacitive load of 1uF from 0V to 6V, and the other way around, in less 10-20uS, at a repetition rate of 10mS (100Hz).
In a PSPICE simulation (with TI LMH6611 model) the output pulsed…
Part Number: LMH6611 Other Parts Discussed in Thread: OPA837 The datasheet SNOSB00K – provides guidance to use Rf between 500 ohms & 1kOhms on page 22/ Figure 68.
Is there a problem with using a higher resistance in the amplifier such as ~ 49…
