FDA2100LV 2 x 180 W / 1 x 300 W PWM digital input power amplifier with built-in diagnostics features and step-up driver Data brief - production data Description The FDA2100LV is a new BCD technology dual bridge class D amplifier, specially intended for car * *36 radio applications. TQFP64 (exposed pad up) Thanks to the BCD6-SOI (Silicon On Insulation) technology it is possible to integrate a high Features performance D/A converter together with powerful MOSFET output amplifier working in class D, to Integrated 105 dB D/A conversion get outstanding efficiency with respect to the 2 I S & TDM digital input (3.3/1.8 V) standard class AB. Input sampling frequency: 44.1kHz, 48 kHz, The D/A conversion on board allows the 96 kHz, 192 kHz performance to reach an outstanding 110 dB S/N Step-up driver included ratio with 105 dB of dynamic range. The feedback EMI control for FM/AM compatibility loop includes the output L-C low-pass filter, Dithering possibility allowing superior frequency response linearity and lower distortion independently of the inductor Capable to operate down to 6 V (e.gstart-sto) and capacitor quality. 6 V - 35 V operating range (R = 8 ) L A full diagnostics array communicates the status Low component count output low-pass filter 2 of each speaker through the I C bus. The Output low-pass filter included in the feedback possibility to control the device by means of the 2 Low radiation function (LRF) I C bus makes FDA2100LV very flexible. High output power capability Thanks to the solutions implemented to solve the 2 x 80 W/4 25 V, 1 kHz, 10 % THD EMI problems, the device can be used in the 2 x 120 W/4 30 V, 1 kHz, 10 % THD standard single DIN car-radio box together with 1 x 150 W/2 25 V, 1 kHz, 10 % THD the tuner. 2 Full I C bus driving (3.3/1.8 V): A built-in step-up driver allows up to 150 W output 2 I C bus digital diagnostics (including DC power with the standard 14 V supply voltage. and AC load detection) AC and DC The FDA2100LV is moreover compliant to the loudspeaker diagnostic most recent OEM specifications for low voltage Very flexible fault detection through integrated operation (so called start-stop battery profile diagnostic during engine stop), helping car manufacturers to Protected against several kinds of reduce the overall emissions and thus misconnections contributing to environment protection.
