9 Power Supply Recommendations
To minimize supply noise, power supplies must be decoupled by a 0.1-μF ceramic capacitor in parallel with a
Due to the nanosecond edges on the output transition, peak supply currents will be drawn during output transitions. Peak current depends on the capacitive loading on the output. The output transition can cause transients on poorly bypassed power supplies. These transients can cause a poorly bypassed power supply to ring due to trace inductance and low self-resonance frequency of high ESR bypass capacitors.
Treat the LMV6x as a high-speed device. Keep the ground paths short and place small (low-ESR ceramic) bypass capacitors directly between the V+ and V– pins.
Output capacitive loading and output toggle rate will cause the average supply current to rise over the quiescent current.
