FDA4100LV 4 x 135 W / 2 x 270 W PWM digital input automotive power amplifier with I2C 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 insulation) technology QUAD BRIDGE class D amplifier, specially intended for car radio applications. HiQUAD-92 (slug-up) Features AEC-Q100 qualified Integrated 108 dB D/A conversion I2S and TDM digital input (3.3/1.8 V) Input sampling frequency: 44.1kHz, 48 kHz, 96 kHz, 192 kHz MOSFET power outputs Step-up driver included EMI control for FM/AM compatibility EMI compliance at the CEI EN 55025 (2009-10) Dithering possibility Very low component count Output low-pass filter included in the feedback Low radiation function (LRF) High output power capability - 4 x 85 W/4 @ 25 V, 1 kHz, 10% THD - 2 x 150 W/2 @ 25 V, 1 kHz, 10% THD Max. output power - 4 x 135 W/4 @ 25 V, 1 kHz - 2 x 270 W/2 @ 25 V, 1 kHz Full I2C bus driving (3.3/1.8 V): - Independent front/rear soft play/ mute - I2C diagnostics (DC and AC load detection, internal test signal generated) Very flexible fault detection though integrated diagnostic Thanks to the technology used, it is possible to integrate a high performance D/A converter together with powerful MOSFET outputs in class D, to get an outstanding efficiency compared with the standard class AB. The integrated D/A converter allows to reach outstanding performances (110 dB S/N ratio with 108 dB of dynamic range). The feedback loop includes the output L-C low-pass filter, allowing superior frequency response linearity and lower distortion independently of the inductor and capacitor quality. FDA4100LV is fully configurable through I2C bus interface and integrates a full diagnostics array specially intended for automotive applications (with the status of each single speaker). Thanks to the solutions implemented to solve the EMI problems, the device is conceived to be used in the standard single DIN car-radio box together with the tuner. The possibility to parallelize the outputs allows to drive both 2 and 1 speakers. A built-in step-up driver allows to provide high output power even using the standard 14 V supply voltage. Moreover FDA4100LV is able to work down to 6 V supply, thus supporting the most recent low voltage ('start-stop') car-makers specification. Table 1.
