1 Multimedia ICs Analog signal I / O interface for portable audio applications BH7760KV The BH7760KV contains the complete audio I / O analog block on a single-chip IC. Therefore, all necessary func- tions for a DVC audio analog I / O interface are provided on one chip. • Applications Portable audio applications • Features 1) Contains the input amplifier, wind noise deletion fil- ter, ALC, 30kHz LPF, line amplifier, stereo head- phone amplifier, and BTL monaural speaker amplifi- er required to configure a analog signal I / O inter- face (audio I / O) all on one chip. 2) With the internal 3-line serial control decoder circuit, serial control enables the setting of the various modes for the IC. • Absolute maximum ratings (Ta = 25°C) • Recommended operating conditions (Ta = 25°C) ParameterSymbolLimits Unit Applied voltage Power dissipation Operating temperature Storage temperature V CC Pd Topr Tstg + 7.0 – 10 ~ + 70 – 55 ~ + 125 V mW °C °C ∗ Reduced by 9.0mW for each increase in Ta of 1°C over 25°C with the IC unmounted. ∗ When mounted on a 70mm × 70mm × 1.6mm glass epoxy board. 900 ∗ ParameterSymbolLimitsUnit Power supply voltage (analog system) Power supply voltage (for SP) Power supply voltage (digital system) AVcc SPVcc DVcc + 4.0 ~ + 6.0 + 4.0 ~ + 6.0 + 2.7 ~ + 3.3 V V V s Not designed for radiation resistance.
