Data brief High efficiency digital input automotive quad power amplifier with built-in diagnostics features, Class-G integrated, ’start stop’ compatible
Features
• AEC-Q100 qualification ongoing GAPGPS00071 • 24-bit resolution PowerSO36 (Slug-up) • High Resolution Bandwidth support: – Up to 40 kHz (I2S 96 kHz) with attenuation [0 dB, -2 dB] – Up to 80 kHz (I2S 192 kHz) with attenuation [0 dB, -2 dB] • 117 dB dynamic range (A-weighted) • Real-time load current monitoring • Voltage monitoring feature on I2C • High Efficiency SB-I (SB-Improved) and Class-G operation • 1 Ω driving capability • High output power capability: – 4 x 27 W 4Ω@ 14.4 V, 1 kHz, THD = 10 % – 4 x 47 W 2Ω@ 14.4 V, 1 kHz, THD = 10 % • Flexible mode control: – Full I2C bus driving (1.8 V/3.3 V) with eight addresses selectable – Independent front/rear play/mute – Selectable digital gains – Very low noise – Digital diagnostic with DC and AC load Detections
Product status link
– Digital diagnostic with OL and OD in play TDA7901 – Current Offset Detection
Product summary
• EMI compliance evaluated following normative CISPR25 • Start-stop compatibility (operation down to 4.5 V)
Order code Package Packing
• Sample rates: 44.1 kHz, 48 kHz, 96 kHz, 192 kHz Tape and TDA7901-ZST PowerSO36 • Flexible serial data port (1.8 V/3.3 V): reel (Slug-up) – I2S standard, TDM 4Ch, TDM 8Ch, TDM 16Ch TDA7901-ZSX Tube • Output Voltage Offset Detector • Independent front/rear clipping detector • Programmable diagnostic pin • CMOS compatible enable pin • Thermal protection • Pop free in mute to play transitions and vice versa
Description
The TDA7901 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.
