Follow to 5V below the negative supply voltage (below ground in good design practice by bypassing the power supplies close single supply operation). No external protection circuitry is to the op amp pins. In most cases 0.1m F ceramic capacitors required, as it is with other common single-supply op amps. are adequate. Furthermore, the OPA1013 is free from phase-reversal prob- lems common with other single-supply op amps. When the SINGLE POWER SUPPLY OPERATION inputs are driven below ground (or below the negative The OPA1013 is specified for operation from a single power power supply), the output polarity remains correct. supply. This means that linear operation continues with the input terminals at (or even somewhat below) ground poten- tial. When used in a non-inverting amplifier, 0V input must COMPARATOR OPERATION produce 0V output. In practice, the output swing is limited The OPA1013 functions well as a comparator, where high to approximately 15mV above ground with no load. Output speed is not required. Sometimes, in fact, the low offset and swing near ground can be optimized when the output load is docile characteristics of the OPA1013 may simplify the connected to ground. If the output must sink current, the design of comparator circuitry. The two op amps in the ability to swing near ground will be diminished. The output OPA1013 use completely independent bias circuitry to avoid swings to within approximately 200mV of ground when interaction when the inputs are over-driven.
