NJW1102

The NJW1102 is a monolithic BiCMOS IC designed for used not only in Dolby Pro-Logic Surround but also in other types of surround systems such as HALL, MATRIX, SIMULATED, etc,. This IC incorporates all functions, necessary for Dolby Pro-Logic and other surround types except time delay. The NJW1102 features serial data control for all functions includin center and surround channel level trim.

The features of NJW1102 can be summarized as (1)dolby operating level: 300mVrms; (2)operating supply voltage range: 5V and 9V - 13V, or ±5V; (3)level trim: -15 to 15dB/1dB step (-15 to 3dB/1dB step at Pro-Logic Mode); (4)internal mode control switches.

The absolute maximum ratings of NJW1102 are (1)supply voltage: Vcc 13.0 V/VDD 6.5V; (2)power dissipation PD SDIP: 700 mW/QFP: 1,000 mW; (3)operating temperature range TOPR: -20~75 °C; (4)storage temperature range TSTG: -40 ~125°C.
