NJW1199 8-CHANNEL ELECTRONIC VOLUME WITH INPUT SELECTOR ■ GENERAL DESCRIPTION The NJW1199 is a 8-channel electronic volume with Input Selector. It includes 13-in 4-out stereo audio selector , REC Output and Multi-channel inputs. The NJW1199 performs low noise and low distortion characteristics with resistance ladder circuit. All of functions are controlled via three-wired serial bus. Selectable 2-Chip address is available for using two chips on same serial bus line. The NJW1199 is suitable for multi-channel audio system, such as AV amplifier, DVD receiver, and others. ■ FEATURES ● Operating Voltage ● 3-Wired Serial Control ● 13-input 4-output stereo selector ● Multi-Channel input (8ch x 2) ● Input Selector Gain Control ● Volume NJW1199FC2 ±4.5 to ±7.5V Chip Address Select Function Gain : 0/-3/-6/-9/-12dB Main 8ch : +31.5 to –95dB / 0.5dB step, Mute Sub 2ch : +31 to –94dB / 1dB step, Mute ● Bi-CMOS Technology ● Package Outline REC B QFP100-C2 REC A ■ BLOCK DIAGRAM ■ PACKAGE OUTLINE Main Volume : +31.5 to -95dB / 0.5dBstep Lout StereoLin Multi-Rin Multi-Lin Input Selector Rout Lout for ADC Rout for ADC Input Selector Gain : 0 / -3 / -6 / -9 / -12dB / Mute StereoRin LSout MultiLSin RSout MultiRSin LBout MultiLBin SUb Volume : +31 to -94dB / 1dBstep Input Selector Cout MultiCin Sub-Lout RBout MultiRBin Sub-Rout SWout MultiSWin Ver 2.3 for web Sub-Rin Sub-Lin REC B REC A Control Logic Data Clock ADR MUTE Latch –1– NJW1199 ■ ABSOLUTE MAXIMUM RATING (Ta=25°°C) PARAMETER SYMBOL RATING UNIT V+/V- +8/-8 V Maximum Input Voltage VIM V Power Dissipation PD V+/V1600 Power Supply Voltage NOTE: EIA/JEDEC STANDARD Test board (76.2x114.3x1.6mm, 2layer, FR-4) mounting mW Operating Temperature Range Topr -40 to +75 °C Storage Temperature Range Tstg -40 to +150 °C ■ ELECTRICAL CHARACTERISTICS (Ta=25°°C, V+/V-=± ±7V, RL=47kΩ Ω, Volume=0dB) PARAMETER SYMBOL TEST CONDITION MIN.
