(1) All voltages are measured with respect to the ground pin, unless otherwise specified.
(2) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for
which the device is functional, but do not ensure specific performance limits. Electrical Characteristics state DC and AC electrical
specifications under particular test conditions which ensure specific performance limits. This assumes that the device is within the
Operating Ratings. Specifications are not specified for parameters where no limit is given, however, the typical value is a good indication
of device performance.
(3) Typicals are measured at 25°C and represent the parametric norm.
(4) Limits are specified to TI's AOQL (Average Outgoing Quality Level).
(5) Datasheet min/max specification limits are specified by design, test, or statistical analysis.
(6) The quiescent power supply current depends on the offset voltage when a practical load is connected to the amplifier.
(7) The NGY0010A package has its exposed-DAP soldered to an exposed 1.2in
2
area of 1oz printed circuit board copper.
(8) The DGK0008BA package is thermally limited to 595 mW of power dissipation at room temperature. Referring to Figure 21 in Typical
Performance Characteristics, the power dissipation limitation for the package occurs at 300 mW of output power. This package limitation
is based on 25°C ambient temperature and θ
JA
= 210°C. For higher output power possibilities refer to POWER DISSIPATION.
