Eeprom 24Lc32; Class Ab Stereo Headphone Driver Tda1308; Saw Filters - Hitachi 42PD3200A Service Manual

9. EEPROM 24LC32

The Microchip Technology Inc. 24AA32A/24LC32A(24XX32A*) is a 32 Kbit Electrically Erasable PROM. The
device is organized as four blocks of 8K x 8-bitmemory with a 2-wire serial interface. Low-voltage design
permits operation down to 1.8V, with standby and active currents of only 1μA and 1mA, respectively. It has
been developed for advanced, low-power applications such as personal communications or data acquisition.
The 24XX32A also has a page write capability for up to 32 bytes of data. Functional address lines allow up to
eight devices on the same bus, for up to 256Kbits address space.

10. CLASS AB STEREO HEADPHONE DRIVER TDA1308

The TDA1308 is an integrated class AB stereo headphone driver contained in a DIP8 plastic package.
The device is fabricated in a 1 mm CMOS process and has been primarily developed for portable digital
audio applications.
