J NJM2096 LOW VOLTAGE DUAL POWER AMPLIFIER @ GENERAL DESCRIPTION @ PACKAGE OUTLINE The NJM2096 is a dual power amplifier, which operates with 1.0V minimum supply voltage. The NJM2096 is suitable to small radio and head-phone stereo. The NJM2096 is resemble to the NJM2076, but two amplifiers are the same. FEATURES Low Operating Voltage (1.0V min) Minimum external components Low Operating Current i DIP8, DMP8, SIP9 Package Outline Bipolar Technology APPLICATION NJM 2086 M @ Head-phone Stereo, Portable Radio, Portable TV, Hand-carry Tele-communication Set. = PIN CONFIGURATION PIN FUNCTION PIN FUNCTION 1 8[] 1.

Stable with large capacitor of less high frequency distortion and worse tand. For example: IwF. tandS0.6 (3) Layout on PCB Be careful to get maximum output power and low distortion set. DIP/DMP: _ Signal ground has to be close to IC ground pin. Impedance of ground line must be low. SIP: Two terminals (Power GND, GND)are connected at one point on PCB. New Japan Radio Co.Ltd. 4-61
