Input crossover distortion is only a problem when the common mode is not held constant. Best performance from any op-amp, be it brand new design or decades old, usually requires the common mode to be constant. So, these op-amps solve a problem that doesn…
Hi Rob,
Thanks for reading! The TIDA-00349 reference design includes more information about the incremental input impedance differences between a typical inductor based buck converter versus a simple charge-pump buck. This the main reason that inductor…
Hi Colin
This is definitely of interest to me. I want to make a 2 wire transmitter with a sensor that doesn't need isolation, and needs 5.5mA @ 5VDC regulated, using XTR11X. I would also have a low power micro, A/D, D/A, total budget 500uA.
I have…
Rail-to-Rail (R/R) op amps are extremely popular, especially useful with low supply voltage. You should know how R/R inputs are accomplished and understand some trade-offs.
Figure 1 shows a typical dual-input R/R stage comprised of both N and P-channel…
Other Parts Discussed in Post: DAC8830 , OPA340 , OPA388 This post is co-authored by Richard Barthel and Errol Leon .
In applications such as position sensors, data-acquisition systems and resistance temperature detectors (RTDs), it is important to design…
In part 5 of this blog series , I discussed the construction of an input-isolated 2-wire sensor transmitter. Input-isolated 2-wire transmitters require isolating the sensor power and data signals from the 2-wire loop supply and 2-wire loop return (RTN…
