8.3 Power Supply Recommendations

The TLV3012x-EP has a recommended operating voltage range (VS) of 1.8 V to 5.5 V. VS is defined as (V+) –

(V-).

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 reference (REF) and logic low

level of the comparator output is referenced to (V-). Output capacitive loading and output toggle rate will cause

the average supply current to rise over the quiescent current in the EC Table.

8.4.1 Layout Guidelines

To minimize supply noise, power supplies should be capacitively decoupled by a 0.1-μF ceramic capacitor.

Comparators are sensitive to input noise and precautions such as proper grounding (use of ground plane),

supply bypassing, and guarding of high-impedance nodes minimize the effects of noise and help to ensure

specified performance.
