LA74310LP

Ordering number : ENA0904 www.DataSheet4U.com Monolithic Linear IC LA74310LP Overview Audio Interface for DSC + Video Driver The LA74310LP is an AV interface IC for digital still cameras (DSCs). It incorporates all the functions necessary for analog audio signal processing for microphone and loudspeaker amplifiers. It also incorporates video output drivers that require no output coupling capacity. The IC is ideal for reducing the number of components and further miniaturization of digital still cameras. Features AUDIO INTERFACE block Three-wire type SERIAL communication MIC AMP, MIC power supply incorporated (with built-in pull-up resistor) ALC PB input method: Analog or digital for inputting (∆Σ) signal 3rd order LPF (for REC/PB switching control, option of fc=4kHz or 11kHz) SPEAKER AMP (The BEEP signal can be mixed.), with electronic VOLUME (controlled by Serial communication) LINE output (with SERIAL MUTE) STANDBY control (current drain < 10µA) VIDEO DRIVER block Not requires output coupling capacity Low voltage drive (VCC=2.7V to 3.6V) V sag does not occur 6th order LPF (fc=9MHz) is built-in. 0µA current dissipation on standby mode. 3 ways amplifier gains (6, 12, 16dB) can be selected. (Pin control (GND/Open/VCC)) The video output has the capacity where one load of 75Ω impedance can be driven.
