Operational Amplifier Parameter Glossary PARAMETER ABBV UNITS DEFINITION INFO Temperature coefficient of input offset voltage Total current into V CC +/ V DD+ Total current out of V DD– αV IO µV/°C mA mA Total harmonic distortion THD dB Total harmonic distortion plus noise THD+N dB Total power dissipation P D mW Turn-on voltage (shutdown) Turn-off voltage (shutdown) V IH– SHDN V IL– SHDN Turn-on time (shutdown) t EN µs Turn-off time (shutdown) t DIS µs Unity gain bandwidth B 1 MHz V V The ratio of the change in input offset voltage to the change in free-air temperature. This is an average value for the specified temperature range. Maximum current that can be supplied to the positive power terminal of the op amp — usually specified as an absolute maximum. Maximum current that can be drawn from the negative power terminal of the op amp — usually specified as an absolute maximum. The ratio of the RMS voltage of the first nine harmonics of the fundamental signal to the total RMS voltage at the output. The ratio of the RMS noise voltage and RMS harmonic voltage of the fundamental signal to the total RMS voltage at the output. The total dc power supplied to the device less any power delivered from the device to a load. Note: At no load: P D = V CC+ × I or P D = V DD+ × I The voltage required on the shutdown pin to turn the device on. The voltage required on the shutdown pin to turn the device off. The time from when the turn-on voltage is applied to the shutdown pin to when the supply current has reached half of its final value. The time from when the turn-off voltage is applied to the shutdown pin to when the supply current has reached half of its final value. The range of frequencies within which the open-loop voltage amplification is greater that unity. 11.3.1 11.3.14 11.3.15 Table 11–2.
