Overview
The LA4166M is a recording and playback system IC that
incorporates an on-chip moter control governor, making it
ideal for use in microcassette and compact cassette recorders. The LA4166M features single-pin control for selecting recording or playback mode and a recording-mode indicator LED driver. The LA4166M is pin-compatible with
the LA4165M. The LA4166M incorporates a preamplifier ,
an automatic level control (ALC) circuit and a power amplifier.
The preamplifier functions as both recording microphone
amplifier and playback equalization amplifier. The ALC
circuit cuts high-level inputs and boosts low-level inputs
during recording. The power amplif ier outputs 215mW (typ)
into a 4Ω speaker. The LA4166M operates from a 1.8 to
3.6V supply and is available in 24-pin MFPs.
