Sanyo LA7058R 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.

Monolithic Linear IC

Overview

The LA7058R, being a video/audio signal processor IC for
UHF band RF modulator use, is suited for RF modulators
that require no TSG (test signal generator). The LA7058R
contains a video clamp circuit, a white clip circuit, and an
audio FM modulator. The characteristics of the LA7058R
are highly stable to supply voltage variations because of

the on-chip voltage regulator.

Functions

• Audio FM modulator.

• Sync pulse peak clamp.

• White clip.

• Voltage regulator.

Features

• Capable of being operated from low supply voltage
(VCC=5V).

• Highly stable to supply voltage variations because of on­chip voltage regulator.

• Excellent frequency characteristic of white clip.

• Large amplitude of audio carrier and less high-frequency
spurious radiation.

• Low audio distortion.

• Low current drain : –30% (compared with our similar
ICs).

• Minimum number of external parts required.

• Small-sized package : 9Z-pin SIP.

Specifications of any and all SANYO products described or contained herein stipulate the performance,
characteristics, and functions of the described products in the independent state, and are not guarantees
of the performance, characteristics, and functions of the described products as mounted in the customer's
products or equipment. To verify symptoms and states that cannot be evaluated in an independent device,
the customer should always evaluate and test devices mounted in the customer's products or equipment.

SANYO Electric Co., Ltd. strives to supply high-quality high-reliability products. However, any and all
semiconductor products fail with some probability. It is possible that these probabilistic failures could
give rise to accidents or events that could endanger human lives, that could give rise to smoke or fire,
or that could cause damage to other property. When designing equipment, adopt safety measures so
that these kinds of accidents or events cannot occur. Such measures include but are not limited to protective
circuits and error prevention circuits for safe design, redundant design, and structural design.
