ISD91260

The ISD91260 series is an audio system-on-chip optimized for low power audio applications such as voice recognition and audio record/playback products. The device embeds ARM® Cortex™-M0 core running up to 50 MHz with 128 K / 64 K byte of non-volatile flash memory and 12 K-byte of SRAM . It also comes equipped with a variety of peripheral devices and serial interfaces. The audio function includes a Sigma-Delta ADC with 91 dB SNR performance coupled with a Programmable Gain Amplifier and volume control in digital domain to enable direct connection of a microphone. Audio output is provided by a Differential Class-D amplifier ( D PWM ) that can deliver 0.5 W of power to an 8 Ω speaker.
