ELECTRICAL CHARACTERISTICS (continued)
(VCC = VCPVDD = VSHDN = 3.6V, VGND = VCPGND = 0V, RIN+ = RIN- = 10kΩ, RFB+ = RFB- = 10kΩ, RFS = 100kΩ, C1 = 4.7F, C2 =
10F; speaker load resistors (RL) are terminated between OUT+ and OUT-, unless otherwise stated; TA = TMIN to TMAX, unless other-
wise noted. Typical values are at TA = +25°C.) (Notes 1, 2)
Note 1:
All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Note 2:
Testing performed with resistive and inductive loads to simulate an actual speaker load. For dynamic speakers,
RL = 8Ω, 68H.
Note 3:
Designed for 1.8V logic.
Note 4:
RIN_ and RFB_ have 0.5% tolerance.
Note 5:
Amplifier inputs AC-coupled to GND.
Note 6:
Testing performed at room temperature with 8
Ω resistive load in series with 68H inductive load connected across BTL
output for speaker amplifier. Mode transitions are controlled by
SHDN. VCP is the peak output transient expressed in dBV.
Note 7:
Voltage gain is defined as: [VOUT+ - VOUT-] / [VIN+ - VIN-].
Note 8:
Mode A tone burst tested at full amplitude for one cycle and half amplitude for nine cycles. Mode B tone burst tested at
full amplitude for three cycles and half amplitude for seven cycles. Full amplitude is defined as 1% THD+N at full battery
(VCC = 4.2V). Electrical Characteristics table targets must be met at THD+N = 1% for one cycle (Mode A) and THD+N <
5% for three cycles (Mode B).
Note 9:
Dynamic range is calculated by measuring the RMS voltage difference between a -60dBFS output signal and the noise
floor, then adding 60dB. Full scale is defined as the output signal needed to achieve 1% THD+N.
