Note 1: All voltages are measured with respect to the ground pin, unless otherwise specified.
Note 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 guarantee specific performance limits. Electrical Characteristics state DC and AC electrical specifications under particular test conditions which
guarantee specific performance limits. This assumes that the device is within the Operating Ratings. Specifications are not guaranteed for parameters where no limit
is given, however, the typical value is a good indication of device performance.
Note 3: The maximum power dissipation must be derated at elevated temperatures and is dictated by T_JMAX, θ_JA, and the ambient temperature T_A. The maximum
allowable power dissipation is P_DMAX = (T_JMAX–T_A)/θ_JA or the number given in Absolute Maximum Ratings, whichever is lower. For the HWD2190, see power derating
curves for additional information.
Note 4: Human body model, 100 pF discharged through a 1.5 kΩ resistor.
Note 5: Machine Model, 220 pF–240 pF discharged through all pins.
Note 6: Typicals are measured at 25˚C and represent the parametric norm.
Note 7: Limits are guaranteed to CSMSC’s AOQL (Average Outgoing Quality Level).
Note 8: For micro SMD only, shutdown current is measured in a Normal Room Environment. Exposure to direct sunlight will increase I_SD by a maximum of 2µA.
Note 9: Datasheet min/max specification limits are guaranteed by design, test, or statistical analysis.
Note 10: ROUT is measured from each of the output pins to ground. This value represents the parallel combination of the 10k ohm output resistors and the two 20k
ohm resistors.
Note 11: If the product is in shutdown mode and V_DD exceeds 6V (to a max of 8V V_DD), then most of the excess current will flow through the ESD protection circuits.
If the source impedance limits the current to a max of 10 ma, then the part will be protected. If the part is enabled when V_DD is greater than 5.5V and less than 6.5V,
no damage will occur, although operational life will be reduced. Operation above 6.5V with no current limit will result in permanent damage.
Note 12: All bumps have the same thermal resistance and contribute equally when used to lower thermal resistance. All bumps must be connected to achieve
specified thermal resistance.
Note 13: Maximum power dissipation (P_DMAX) in the device occurs at an output power level significantly below full output power. P_DMAX can be calculated using
Equation 1 shown in the Application section. It may also be obtained from the power dissipation graphs.
Note 14: PSRR is a function of system gain. Specifications apply to the circuit in Figure 1 where A_V = 2. Higher system gains will reduce PSRR value by the amount
of gain increase. A system gain of 10 represents a gain increase of 14dB. PSRR will be reduced by 14dB and applies to all operating voltages.
