PARAMETER
All devices are 100% production tested at room temperature. All temperature limits are guaranteed by design.
Testing performed with resistive and capacitive loads to simulate an actual ceramic/piezoelectric speaker load,
Z
Input DC bias voltage determines the maximum voltage swing of the input signal. Inputing a signal with a peak voltage
of greater than the input DC bias voltage results in clipping.
1.8V logic compatible.
Amplifier/inputs AC-coupled to GND.
Testing performed at room temperature with 10Ω resistive load in series with 1µF capacitive load connected across the BTL
output for speaker amplifier. Mode transitions are controlled by SHDN. V
Voltage gain is defined as: [V
PV
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.
