Seiko NPC develops products by fully using our lengthy experience with digital and analog circuit design technologies. We have acquired abundant experience and know-how in such process technologies as CMOS and BiCMOS. Seiko NPC's broad lineup can satisfy your needs by offering you the greatest choice of the most suitable products.
Seiko NPC offers analog audio ICs, using CMOS technologies. We also offer digital audio ICs, which are based on our signal processing technology which we have cultivated since the advent of the first digital audio system.
The digital audio ICs include high-performance digital filters, DA converters, sample rate converters, and sound skip prevention ICs.
For the analog audio ICs, we offer electronic volume controls for analog sound, headphone amplifiers with built-in electronic volume control, and surround ICs.
Seiko NPC's video buffer ICs consist of a lowpass filter to handle the video signal band, and an output buffer. Because their cutoff frequency can be freely set externally, our video buffer ICs cover a wide range of video signals, from ground wave to HD broadcasting.
These ICs are available in a wide range of products that are intended for DTV, PDP, DVD, projectors, digital cameras, and car navigation systems.
| Crystal oscillator applications |
Seiko NPC offers a wealth of crystal oscillator ICs used to satisfy a variety of needs in electronic devices.
Seiko NPC's years of know-how as well as our original technologies and ancillary functions provides you with excellent oscillation start-up, stable oscillation, and output waveform in these ICs.
Our diverse assortment of clock generators supports a wide range of applications, such as DVD players and digital cameras, where more than one clock is necessary. All these clock generators flexibly support your output frequency requirements, and are easy to use in set designs, due to their low jitter characteristics and low current consumption.
| Communication applications |
Seiko NPC offers FSK/DTMF receiver ICs and DTMF tone dialer ICs for communication applications using analog telephone circuits. We also offer general-purpose PLLs, PLLs for pagers, and POCSAG decoders.
Seiko NPC produces drivers for ELs and white LEDs used in digital cameras, mobile devices, and PDAs. The EL driver can handle from small to large EL sheets and is capable of highly efficient, stable driving. The white LED driver can light from two to four LEDs connected in series, lowering dispersion in luminance among the serial LEDs and thus contributing to cost reduction, power conservation, and miniaturization in an application.
| Power supply applications |
Seiko NPC's battery chargers, which are ICs purposed for charging nickel-hydrogen and nickel-cadmium batteries, ensure safe, high-speed charging with just a few components.
The power supplies we offer are setup type DC/DC converter ICs that provide high efficiency and low power consumption through PFM control.
Seiko NPC offers a variety of analog clock and watch ICs featuring low power consumption. We also offer real-time clocks that can use a wide range of supply voltages that lets you employ them in a variety of applications.
