NTE891M Dual Audio Operational Amplifier PDIP-8
Info als pdf File
See also >>> NTE891SM
Description:
The NTE891M and NTE891SM are dual general purpose operational amplifiers designed with particular emphasis on performance in audio systems. These 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 HiHi 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 8-Lead Mini DIP (NTE891M) and Surface Mount SOIC-8 (NTE891SM)
