NJM2153 SOUND ENHANCEMENT AUDIO PROCESSOR ■ GENERAL DESCRIPTION The NJM2153 is a sound enhancement audio processor for professional audio equipments. It regenerates high definitive and nearly real sound. The internal VCA (voltage controlled amplifier) suppresses the boost gain in high band to reduce noise when faint signals are inputted. The NJM2153 is suitable for mixer and effecter for musical instruments, and high-end audio equipment requiring low distortion and wide dynamic range. ■ PACKAGE OUTLINE NJM2153M ■ FEATURES ● Operating Voltage (±9 to ±18V) ● Low Operating Current (5.2mA typ.) ● Low Output Noise (20µVrms typ. at BBE ON) ● Low Distortion (0.02% typ. at BBE ON) ● Internal BBE ON/OFF Switch ● Bipolar Technology ● Package Outline DMP20 ■ BLOCK DIAGRAM OUT IN VCA DETECT PEAK -1- NJM2153 ■ ABSOLUTE MAXIMUM RATING (Ta=25°C) PARAMETER Supply Voltage Power Dissipation Operating Temperature Range Storage Temperature Range SYMBOL + V /V PD Topr Tstg + RATING ±20 350 -40 to +85 -40 to +125 UNIT V mW °C °C - ■ ELECTRICAL CHARACTERISTICS (V /V =±15.0V,Ta=25°C,Vin=-12dBV/1kHz,Rg=600Ω,RL=100kΩ) PARAMETER Operating Voltage Supply Current SYMBOL + Icc Mid Voltage Gain GVMF High Voltage Gain 1 GVHF1 High Voltage Gain 2 GVHF2 High Voltage Gain 3 GVHF3 Attack Time TATC Recovery Time TRCV Maximum Input Voltage VIM Maximum Output Voltage VOM Output Noise 1 VNO1 Output Noise 2 VNO2 Total Harmonic Distortion 1 THD1 Total Harmonic Distortion 2 THD2 Vth MIN.
