| NTE891M & NTE891SM Integrated Circuit Dual Audio Operational Amplifier Description: The NTE891M and NTE891SM are dual general purpose operational amplifiers designed with particular emphasis on performance in audio systems. Thiese devices deliver low noise, high speed and wide bandwidth without increasing external components for all closed loop gains and is therefore optimized for all preamp and high level stages in PCM and HiFi systems. Features: D Wide Dynamic Range D Low Input Noise Voltage D High Slew Rate D High Gain Bandwidth Product D Wide Power Bandwidth D Low Distortion D Low Offset Voltage D Large Phase Margin D Available in 8-Lead Mini DIP (NTE891M) and Surface Mount SOIC-8 (NTE891SM) Absolute Maximum Ratings: Supply Voltage, VCC - VEE . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36V Differential Input Voltage (Note 1), VID . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30V Input Voltage Range (Note 1), VIC . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V Power Dissipation (Note 2), PD . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mW Operating Temperature Range, Topr . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -40 to +85C Storage Temperature Range, Tstg . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . -60 to +150C Lead Soldering Temperature (10 seconds), TL . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +260C Note 1.
