InnoMain is probably the most cost-effective amplifier platform in the market. Based on a low-cost system-on-chip which integrates an industry-standard ARM Cortex CPU core with dedicated DSP engine offering up to 800 MFLOPS of processing power, a 4-channel high-quality audio ADC, a CAN FD controller and other communication and audio I/O peripherals.
Combining this SOC with a System-Basic-Chip and integrated Class-AB and/or Class-D output stages, a powerful solution for entry-level to mid-range automotive sound systems has been created.
Integrating the InnoPower digital boost supply technology, the output power of each stage can be scaled up to 150W/channel.
SW-wise a full-featured real-time operating system enables simple and fast changes of the application software. For Audio processing the crispAudio iFidelity Suite is used – DSPConcepts‘ Audio Weaver can be integrated as well on request as well as other 3rd party algorithms available for the ARM Cortex familty.
The InnoMain reference amplifier is available with 8 Class-AB output stages, 4 analogue inputs and CAN, LIN and A2B connectivity today. CrispAudio also provides the Automotive OEM Diagnostics stack for CAN, LIN and A2B.
