ELECTRICAL CHARACTERISTICS (continued)

(VPVDD = 20V, VVS = 5V, VAGND = VPGND = 0V, VMOD = VSHDN = VMUTE = 5V, REGEN = MONO = AGND, C1 = 0.1μF, C2 = 1μF,

RIN_ = 20kΩ and RFB_= 20kΩ, RL = ∞, AC measurement bandwidth 22Hz to 22kHz, TA = TMIN to TMAX, unless otherwise noted.

Typical values are at TA = +25°C.) (Notes 4, 5)

All devices are 100% production tested at +25°C. All temperature limits are guaranteed by design.

Stereo mode (MONO = GND) specified with 8Ω resistive load in series with a 68μH inductive load connected across BTL

outputs. Mono mode (MONO = 5V) specified with a 4Ω resistive load in series with a 33μH inductive load connected

across BTL outputs.

Output swing is specified with respect to VCOM.

For typical applications, an external 5V supply is not required. Therefore, set REGEN = 5V. If thermal performance is a

concern, set REGEN = 0V and provide an external regulated 5V supply.

Output amplifier gain is defined as:

Note 9: Amplifier inputs AC-coupled to GND.

Note 10: Specified at room temperature with an 8Ω resistive load in series with a 68μH inductive load connected across BTL outputs.

Mode transitions controlled by SHDN control pin.
