NJM8068 Low Noise, Bipolar Input Dual Audio Operational amplifier ■ DESCRIPTION NJM8068 is a low noise bipolar input dual audio operational amplifier has 3.5nV/√Hz at 1kHz. The NJM8068 features Low distortion, high slew rate, wide bandwidth and high open-loop gain. In addition, unity-gain stable allows voltage-follower operation. These features make NJM8068 ideal for audio pre amplifier, microphone amplifier, line amplifier and other audio applications. NJM8068 operate over a wide temperature range of -40°C to +125°C, making this IC ideal for use in industrial measurement instruments. The NJM8068 is available in the 8-pin SOP8 and MSOP8 (TVSP8) packages. ■ PACKAGE OUTLINE ■ FEATURES ●Designed for High-Quality Sound ●Low Noise 3.5nV/ Hz at 1kHz ●Low Distortion 0.001% ●Slew Rate 6.8V/µs ●Gain Bandwidth Product 19MHz ●Open-Loop Voltage Gain 120dB ●Unity-Gain stable ●Bipolar Input ●Supply Voltage ±4V to ±18V ●Operating Temperature -40°C to +125°C ●Supply Current (All Amplifier) 5mA typ. ●Package SOP8 MSOP8(TVSP8)* *MEET JEDEC MO-187-DA / THIN TYPE ■ PIN CONFIGURATION ■ APPLICATIONS ●Professional Audio sets ●Audio pre/microphone amplifiers ●Analog/Digital mixer ●AV Receiver ●Car Audio ●Industrial Measurement Instruments ■ Related Products NJM8068G (SOP8) NJM8068RB1 (MSOP8(TVSP8)) (Top View) A OUTOUT 1 8 V+ A -INPUT 2 7 B OUTPUT A +INPUT 3 6 B -INPUT V- 4 5 B +INPUT Package Product Name SOP8 NJM8068G TVSP8 NJM8068RB1 Features Product 5nV/√Hz, 0.0005%, 5V/μs, 15MHz NJM8080 (Low Noise, Low distortion Audio OP-AMP) ■ BLOCK DIAGRAM (1 amplifier) © New Japan Radio Co.,Ltd.

(2) Input voltage is the voltage should be allowed to apply to the input terminal independent of the magnitude of V+. The normal operation will establish when any input is within the Common Mode Input Voltage Range of electrical characteristics. (3) Power dissipation is the power that can be consumed by the IC at Ta=25°C, and is the typical measured value based on JEDEC condition. When using the IC over Ta=25°C subtract the value [mW/°C]=PD/(Tstg(MAX)-25) per temperature. 2-layer: EIA/JEDEC STANDARD Test board (76.2x114.3x 1.6mm, 2layers, FR-4) mounting 4-layer: EIA/JEDEC STANDARD Test board (76.2x114.3x 1.6mm, 4layers, FR-4) mounting ■ RECOMMENDED OPERATING CONDITIONS (Ta=25°C) PARAMETER SYMBOL + Supply Voltage ■ ELECTRICAL TEST CONDITION - V /V MIN.
