9 Power Supply Recommendations

The TLV7011 and TLV7021 have a recommended operating voltage range (VS) of 1.4 V to 5.5 V. VS is defined

as VCC – VEE. Therefore, the supply voltages used to create VS can be single-ended or bipolar. For example,

single-ended supply voltages of 5 V and 0 V and bipolar supply voltages of +2.5 V and –2.5 V create comparable

operating voltages for VS. However, when bipolar supply voltages are used, it is important to realize that the logic

low level of the comparator output is referenced to VEE.

10 Layout

10.1 Layout Guidelines

A power-supply bypass capacitor of 100 nF is recommended when supply output impedance is high, supply

traces are long, or when excessive noise is expected on the supply lines. Bypass capacitors are also

recommended when the comparator output drives a long trace or is required to drive a capacitive load. Due to

the fast rising and falling edge rates and high-output sink and source capability of the TLV7011 and TLV7021

output stages, higher than normal quiescent current can be drawn from the power supply. Under this

circumstance, the system would benefit from a bypass capacitor across the supply pins.
