ISD15D00 Digital ChipCorder with Digital Audio Interface DATASHEET
■The ISD15D00 is a digital ChipCorder® featuring digital compression, comprehensive memory management, and integrated analog/digital audio signal paths. The ISD15D00 utilizes serial flash memory to provide non-volatile audio playback for a two-chip solution. The ISD15D00 provides an I²S digital audio interface, faster digital programming, higher sampling frequency, and a signal path with SNR 80dB.
■The ISD15D00 can take digital audio data via I²S or SPI interface. When I²S input is selected, it will replace the analog audio inputs and will support sample rates of 32, 44.1 or 48kHz depending upon clock configuration. When SPI interface is chosen, the sample rate of the audio data sent must be one of the ISD15D00 supported sample rates.
■The ISD15D00 has inbuilt analog audio inputs, analog audio line driver, and speaker driver output. The analog audio input, Aux-in, has a fixed gain configured by SPI command. Aux-in can directly feed-through to the analog outputs; it can also mix with the DAC output and then feed-through to the analog outputs.
■Analog outputs are available in two forms: (1) Aux-out is an analog single-ended voltage output; (2) Class-AB BTL(bridge-tied-load) is an analog differential voltage output. Class-AB BTL delivers 0.7-watt output power at V-CCSPK= 4.5V
■Class-D PWM direct-drive is also available, which delivers 0.9-watt output power at V-CCSPK= 4.5V.
