FDA4100LV 4 x 135 W / 2 x 270 W PWM digital input automotive power amplifier 2 with I C diagnostics, step-up driver and low voltage operation Data brief 6 V operation (start - stop) Description 0 03 The FDA4100LV is a new BCD- SOI (silicon on HiQUAD-92 (slug-up) insulation) technology QUAD BRIDGE class D amplifier, specially intended for car radio Features applications. AEC-Q100 qualified Thanks to the technology used, it is possible to integrate a high performance D/A converter Integrated 108 dB D/A conversion together with powerful MOSFET outputs in class 2 I S and TDM digital input (3.3/1.8 V) D, to get an outstanding efficiency compared with Input sampling frequency: 44.1kHz, 48 kHz, the standard class AB. 96 kHz, 192 kHz The integrated D/A converter allows to reach MOSFET power outputs outstanding performances (110 dB S/N ratio with Step-up driver included 108 dB of dynamic range). The feedback loop includes the output L-C low-pass filter, allowing EMI control for FM/AM compatibility superior frequency response linearity and lower EMI compliance at the CEI EN 55025 (2009-10) distortion independently of the inductor and Dithering possibility capacitor quality. Very low component count 2 FDA4100LV is fully configurable through I C bus Output low-pass filter included in the feedback interface and integrates a full diagnostics array specially intended for automotive applications Low radiation function (LRF) (with the status of each single speaker). High output power capability Thanks to the solutions implemented to solve the 4 x 85 W/4 25 V, 1 kHz, 10% THD EMI problems, the device is conceived to be used 2 x 150 W/2 25 V, 1 kHz, 10% THD in the standard single DIN car-radio box together Max. output power with the tuner. 4 x 135 W/4 25 V, 1 kHz The possibility to parallelize the outputs allows to 2 x 270 W/2 25 V, 1 kHz drive both 2 and 1 speakers. 2 A built-in step-up driver allows to provide high Full I C bus driving (3.3/1.8 V): output power even using the standard 14 V Independent front/rear soft play/ mute supply voltage. 2 I C diagnostics (DC and AC load detection, Moreover FDA4100LV is able to work down to 6 V internal test signal generated) supply, thus supporting the most recent low Very flexible fault detection though integrated voltage ( start-stop ) car-makers specification. diagnostic Table 1.
