Description
The TDA7803A is a single chip quad bridge amplifier in advanced BCD technology integrating: a full D/A converter, digital input for direct connection to I2S (or TDM) and powerful MOSFET output stages.
The integrated D/A converter allows the performance to reach an outstanding 115 dB S/N ratio with more than 110 dB of dynamic range.
Features
• AEC-Q100 qualified
• 24-bit digital processing
• 115 dB dynamic range (A-weighted)
• SB-I (SB - improved) high efficiency operation
the highest ’non - class D’ efficiency
• Parallel mode function availability
• High output power capability:
– 4 x 27 W 4Ω@ 14.4 V, 1 kHz, THD = 10%
– 4 x 47 W 2 Ω @ 14.4 V, 1 kHz, THD = 10%
• Flexible mode control:
– Full I2C bus driving 1.8V/3.3V) with four
addresses selectable (only for PowerSO36
package option)
– Independent front/rear play/ mute
– Selectable digital gains for very-low noise
line-out function
– Digital diagnostic with DC and AC load
detections
