ANALOG CHARACTERISTICS

(Test conditions (unless otherwise specified): RS =0; RL =2kΩ; CL = 20 pF; 10 Hz to 20 kHz Measurement Band-

width)

Vin =[(VFS Max -VFS Min)-1.6V]Vp-p, 1 kHz, Volume = 0 dB.

Note that for (VA+) = -(VA-) = 5 V, Vin =5.7 Vp-p =2VRMS.

Measured with input grounded and volume = 0 dB. Will increase as a function of volume settings >0 dB.

Power-down is defined as RESET = low, all clock and data lines held static, and no analog input signals

applied.
