* Typical figures are at 25°C with nominal+ 5V supplies and are for design aid only: not guaranteed and not subject to production testing.
♣ The 2W impedance and THL are modified to the required value by external feedback applied by the programmable codec to the hybrid where required.
Values quoted are for the hybrid on its own with no external feedback. Ref. 600Ω, 300Hz to 3400Hz
