NJM4580 datasheet


Description :

The NJM4580 is a dual operational amplifier, specially designed for improving the tone control, which is most suitable for the audio application.

Featuring noiseless, higher gain bandwidth, high output current and low distortion ratio, and it is most suitable not only for acoustic electronic parts of audio pre-amp and active filter, but also for the industrial measurement tools.

It is also suitable for the head phone amp at higher output current, and further more, it can be applied for the handy type set operational amplifier of general purpose in application of low voltage single supply type which is properly biased of the low voltage source. The D-Rank type products (NJM4580DD / NJM4580LD / NJM4580MD / NJM4580ED) have specified maximum limits for equivalent input noise voltage.

Features :

1. Operating Voltage  ±2V~±18V

2. Low Input Noise Voltage  0.8µVrms typ. (RIAA)

3. Wide GBW  15MHz typ.

4. Low Distortion  0.0005%typ.

5. Slew Rate  5V/µs typ.

SAF7741 datasheet

Description :

The SAF7741 is a combined Intermediate-Frequency (IF) car radio and audio Digital
Signal Processor (DSP) with several powerful cores integrated onto a single device. It
combines analog IF input, digital radio and audio processing, sample-rate converters and
digital and analog audio output to enhance listening clarity and noise suppression while
reducing multipath channel effect.


1. Dual/Single, low-IF car radio and audio software DSP
2. Low-IF concept for high performance at reduced system cost
3. New PDC including IQC
4. Dedicated dual digital radio interface to co-processors for HD Radio and DRM
5. Supports co-processors for any digital radio standard such as DAB/DMB and SDARS


The SAF7741HV is designed for use in high-performance car radio systems.
