NOTES: (1) Dynamic performance specs are tested with external 20kHz low pass filter and THD-B specs are test with 30kHz LPF, 400Jz HPF, Average Mode,
Shibasoku #725 THD Meter. (2) RSTB pin, MD pin, MC pin, and ML pin include an internal pull-up resistor. (3) RSTB pin, MD pin, MC pin, and ML pin include
internal Schmitt trigger circuits. (4) ZERO pin is an open drain output. (5) Line output should be connected by a coupling capacitor. (6) Headphone output should
be connected by a coupling capacitor. (7) Supply current and power dissipation are measured at CLKO pin = no load, XTO pin = no load.
