This low-power, 3- volt product enables customers to quickly and easily integrate 4 to 8 minutes of voice storage features such as one-way and two-way (full du- plex) call record, voice memo record, and call screening/answering machine functionality. Like other ChipCorder products, the ISD5008 inte- grates the sampling clock, anti-aliasing and smoothing filters, and the multi-level storage array on a single-chip. For enhanced voice features, the ISD5008 eliminates external circuitry by also in- tegrating automatic gain control (AGC), a power amplifier/speaker driver, volume control, sum- ming amplifiers, analog switches, and a car kit in- terface. Input level adjustable amplifiers are also included, providing a flexible interface for multiple applications.
