Sanyo LA8515N Specifications
Any and all SANYO products described or contained herein do not have specifications that can handle
applications that require extremely high levels of reliability, such as life-support systems, aircraft’s
control systems, or other applications whose failure can be reasonably expected to result in serious
physical and/or material damage. Consult with your SANYO representative nearest you before using
any SANYO products described or contained herein in such applications.
SANYO assumes no responsibility for equipment failures that result from using products at values that
exceed, even momentarily, rated values (such as maximum ratings, operating condition ranges,or other
parameters) listed in products specifications of any and all SANYO products described or contained
herein.

Overview
The SANYO LA8515N telephonic speech network provides
amplification, switching and line drive functions for telephone equipment. It can perform 2 to 4 line conversion and
impedance matching, and supports both DTMF and keytone
signals.
The LA8515N’s low operating current reduces line load.
Switching between the DTMF/keytone and voice circuits
is controlled directly from a single MUTE input.
The LA8515N is available in plastic 20-pin DIPs.
Features
• Direct connection to low-impedance receiver.
• DTMF/keytone and voice circuit switching controlled by
a single MUTE input.
• Receive and transmit gain are adjusted automatically in
response to the line current.
• Applicable to a wide v ariety of tr ansmitters and receivers
by selecting external components.
