Note 1: All devices 100% production tested at T A = +85°C. Limits over the operating temperature range are guaranteed by design.
Note 2: Treble = bass = 0dB. C CB_ = open, C CT _ = short, left input signal = right input signal = +2V.
Note 3: See Tables 3 and 4 and Figure 7. V DD = +2.7V, V SS = -2.7V.
Note 4: Guaranteed by design.
Note 5: Measured with A-weighted filter.
Note 6: Supply current measured while attenuator position is fixed.
Note 7: Set _OUT = 0dB and shutdown device SHDN = 0. t
WU is the time required for _OUT to reach 0dB after SHDN goes high.
