PHILIPS TEA0679T I 2 C-bus controlled dual Dolby* B-type noise reduction circuit for playback applications handbook
TEA0679T is a dual Dolby B noise reduction circuit with head and equalization amplifiers for use in car radios.
PHILIPS TEA0678 Dual Dolby* B-type noise reduction circuit automatic music search with differential outputs mute handbook
TEA0678 is a bipolar integrated circuit that provides two channels of Dolby B noise reduction for playback applications in car radios. It includes head and equalization amplifiers with electronically switchable time constants. Furthermore it includes electronically switchable inputs for tape drivers with reverse heads. This device also detects pauses of music in Automatic Music Search (AMS) mode, with a delay time fixed externally by a resistor. The short-circuit proof output stage of the TEA0678 is differential and provides muting. The device will only output a signal when both NR channels are active.
PHILIPS TEA0677T handbook
TEA0677T is a monolithic bipolar integrated circuit intended for applications in car radios. It includes head and equalization amplifiers with electronically switchable time constants. Furthermore it includes electronically switchable inputs for tape drives with reverse heads. The device is intended to replace the regular TEA0675T in low-cost car radios using the same PCB. External components that are necessary for Dolby B and music search features can be omitted.
PHILIPS TEA0676T handbook
The TEA0676T is a monolithic bipolar integrated circuit intended for applications in car radios. It includes head and equalization amplifiers with electronically switchable time constants. Furthermore it includes electronically switchable inputs for tape drivers with reverse heads.
PHILIPS TEA0675 handbook
This document describes the features and applications of the TEA0675 Dual Dolby B-type noise reduction circuit, including dual noise reduction channels, head pre-amplifiers, reverse head switching, etc.
Philips Semiconductors LM124/224/324/324A/ SA534/LM2902 handbook(1)
Philips Semiconductors LM219/319 handbook
The LM319/319 are high-speed dual comparators fabricated on a single monolithic chip. They are designed to operate over a wide range of supply voltages down to a single 5V logic supply and ground. Further, they have higher gain and lower input currents than devices like the μA710. The uncommitted collector of the output stage makes the LM319 compatible with RTL, DTL, and TTL as well as capable of driving lamps and relays at currents up to 25mA. Although designed primarily for applications requiring operation from digital logic supplies, the LM319 series are fully specified for power supplies up to ±15V. It features faster response than the LM111 at the expense of higher power dissipation. However, the high-speed, wide operating voltage range and low package count make the LM319 much more versatile than older devices like the μA711.
