LV1605M Datasheet Monolithic Linear IC Analog Signal Processor

Manufacturer: SANYO (now Panasonic)

Overview

www.DataSheet4U.com Ordering number : ENN*7809 Preliminary SANYO Semiconductors DATA SHEET Monolithic Linear IC LV1605M Overview Analog Signal Processor for CD Players The LV1605M implements the analog signal processing and servo control required by compact disc players, and, when combined with a CD DSP such as the LC78604E or LC78605E, can implement a CD player with a minimal parts count.

The LV1605M also provides a gain switching pin to allow it to support playback of CD-RW discs.

Functions IV amplifier, RF amplifier (with AGC and hold function on defect detection), APC, FE (with VCA), TE (with VCA and auto-balance), focus servo amplifier (with offset canceller and hold function on defect detection), tracking servo amplifier (with offset canceller and hold function on defect detection), spindle servo amplifier (with gain switching function and hold function on defect detection), sled servo amplifier (with on/off function and hold function on defect detection), focus detection (DRF and FZD), track detection (HFL and TES), defect detection, shock detection, and disc mode gain switching function.
