Note 1:
All devices are 100% production tested at TA = +25°C. Specifications over temperature limits are guaranteed by design.
Note 2:
Total quiescent current depends on overall efficiency and varies with the LX inductor value and ESR, diode turn-on volt-
age, and the parasitic losses in all external components.
Note 3:
Input DC bias voltage determines the maximum voltage swing of the input signal. An input signal with an amplitude
greater than the input DC bias voltage results in clipping.
Note 4:
Amplifier inputs AC-coupled to GND.
Note 5:
Voltage gain is defined as [VOUT+ - VOUT-]/[VIN+ - VIN-].
Note 6:
VOUT is defined as [VOUT+ - VOUT-].
Note 7:
Matching of external AC-coupling input capacitors and gain resistors is critical to achieving good CMRR.
Note 8:
Dynamic range 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.
Note 9:
Peak output current depends on external power-supply components and the signal frequency.
Note 10: Boost converter current limit is tested with a DC sweep. Actual current-limit values under transient conditions may be high-
er. At high input supply, VBAT, and low inductance, L, transient current limit might be higher than 1.7A.
