Section 3. Typical Connection Diagrams to show 10 μ F and 0.1 μ F power-supply decoupling
capacitors.
– Reorganized location of individual specifications in electrical characteristics tables based on measured
device performance in different operational modes ( “Electrical Characteristics - All Operational Modes”
on page 9 , “Electrical Characteristics - SD Mode” on page 10 , “Electrical Characteristics - FSD Mode”
on page 11 , “Electrical Characteristics - HD Mode” on page 12 , and “Electrical Characteristics - FHD
Mode” on page 13 ).
– The following specification changes have been made in “Electrical Characteristics - SD Mode” on
page 10 , “Electrical Characteristics - FSD Mode” on page 11 , “Electrical Characteristics - HD Mode” on
page 12 , and “Electrical Characteristics - FHD Mode” on page 13 :
– Added “Common-Mode Rejection Ratio” test conditions (V
ripple
= 1 V
PP
and f
ripple
= 217 Hz)
– Updated “Signal to Noise Ratio” to be specified as A-Weighted
– Updated “Idle Channel Noise” to be specified as both A-Weighted & Unweighted
– Updated “Idle Current Draw” to be specified with no load at 3 voltages (5.0 V, 4.2 V, and 3.7 V)
– Changed “Max Input Before Clipping specification to “Input Voltage @ 1 % THD+N”
– Updated specification typical values for 1% Output Power, 10% Output Power, THD+N @ 1 W, SNR
A-Weighted, Idle Channel Noise A-Weighted, Idle Channel Noise (unweighted), Frequency
Response, Output Switching Frequency, Input Impedance, and Input Voltage @ 1% THD+N
– Updated “Operating Efficiency” to be specified with 8 Ω + 33 μ H and 4 Ω + 33 μ H in “Electrical
Characteristics - All Operational Modes” on page 9 .
– Modified “Power-Up Time” specification into “Start-Up Time” and “Zero Crossing Power-Up” and added
a cross-reference in “Power-Up & Power-Down Characteristics” on page 14 .
– Moved power-up and power-down timing specifications from “Electrical Characteristics - All Operational
Modes” on page 9 to their own specification table, “Power-Up & Power-Down Characteristics” on
page 14 .
– Renamed “Thermal Error Wait Time (W
TE
)” to “Thermal Error Retry Time (R
TE
)” in “Electrical
Characteristics - All Operational Modes” on page 9 and in Section 5.5 Over Temperature Protection and
added (Note 10) Thermal Error cross reference from spec table to description section.
– Updated “Operating Efficiency” specification ( η) in “Electrical Characteristics - All Operational Modes”
on page 9 .
– Updated “MOSFET On Resistance” specification (R
DS(ON)
) in “Electrical Characteristics - All
Operational Modes” on page 9 .
