LA7256規(guī)格書詳情
Overview
The LA7256 provides the record and playback amplification functions required for high-fidelity audio signal processing in VCR systems. The record system supports S-VHS and over-recording, and also supports the provision of an adjustment-free record current by using a constant-current regulated output scheme incorporating an AGC circuit. The playback system consists of a high-gain preamplifier with a small DC offset, and includes a builtin EP gain increasing function.
Features
? Minimal number of required external components
? The playback amplifier output DC offset is small.
? Built-in EP mode gain emphasis
? Record AGC that handles three modes (for an
adjustment-free record current)
? Built-in buffer amplifier that can be used to construct an
active filter.
Functions
? Preamplifier (two channels)
? RF switching between CH1 and CH2
? Record AGC amplifier (for over-recording and S-VHS)
? Constant-current regulated output record amplifier
? Buffer amplifier that can be used in both record and
playback
