Monolithic Linear IC
LA7058R
Video, Audio Signal Processor for UHF Band RF Modulator Use
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.

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. In the event that any or all SANYO products(including technical data,services) described or contained herein are controlled under any of applicable local export control laws and regulations, such products must not be expor ted without obtaining the expor t license from the authorities concerned in accordance with the above law.
