Shenzhen Meiyuxin Technology Co., Ltd. [recycling factory waste materials] supply TPA2005D1DGNRQ1 automotive 1.4W mono, analog input class D audio amplifier quality assurance brand new original! ! !

Product Description:

The TPA2005D1-Q1 device is a 1.4-W high-efficiency filterless Class-D audio power amplifier in a SON or MSOP-PowerPAD package requiring only three external components.

Features such as 84% efficiency, –71-dB PSRR @ 217 Hz, improved RF rectification immunity, and 15-mm2 total PCB area make the TPA2005D1-Q1 ideal for low-power audio applications in infotainment and clusters.

The device achieves independent gain control by summing the signals for each function while reducing noise to only 48 µVRMS. In addition, the TPA2005D1-Q1 device offers a fast start-up time of 9 ms with minimal pop and pop, and features short-circuit and thermal protection.

Features:

• Qualified for automotive applications

• AEC-Q100 qualified with the following results:

– Device Temperature Grade 3 (DRB and DGN packages without T suffix): –40°C to +85°C ambient operating temperature range

– Device temperature grade 2 (DGN package T suffix): –40°C to +105°C ambient operating temperature range

– Equipment HBM classification level 2

– Equipment CDM classification level C5

• 1.4 W into 8 Ω from 5 V supply THD = 10% (typical)

• Longest battery life and least heat

– Efficiency of 8 Ω speaker:

– 84% at 400 mWh

– 79% at 100 mWh

– 2.8mA Quiescent Current

– 0.5µA Shutdown Current

• Only three external components

– Optimized PWM output stage eliminates LC output filter

– Internally Generated 250 kHz Switching Frequency Eliminates Capacitors and Resistors

– Improved PSRR (–71 dB at 217 Hz) and wide supply voltage (2.5 V to 5.5 V) eliminate the need for voltage regulators

– Fully differential design reduces RF rectification and elimination of bypass capacitors

– Improved CMRR eliminates two input coupling capacitors

• Space saving package

Application:

• Head unit

• Telematics

• Emergency call (eCall)

• noise generator
