NTE891M & NTE891SM Integrated Circuit Dual Audio Operational Amplifier Description: The NTE891M and NTE891SM are dual general purpose operational amplifiers designed with partic- ular 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 opti- mized for all preamp and high level stages in PCM and HiFi systems. Features: Wide Dynamic Range Low Input Noise Voltage High Slew Rate High Gain Bandwidth Product Wide Power Bandwidth Low Distortion Low Offset Voltage Large Phase Margin Available in 8Lead Mini DIP (NTE891M) and Surface Mount SOIC8 (NTE891SM) Absolute Maximum Ratings: Supply Voltage, V V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 36V CC EE Differential Input Voltage (Note 1), V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 30V ID Input Voltage Range (Note 1), V . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 15V IC Power Dissipation (Note 2), P . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 500mW D Operating Temperature Range, T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 40 to +85C opr Storage Temperature Range, T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . 60 to +150C stg Lead Soldering Temperature (10 seconds), T . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . . +260C L Note 1. If supply voltage is less than 15V, it is equal to supply voltage. Note 2. This is a permissible value at T +85C.
