Overview
The LA7837,7838 are vertical deflection output ICs developed for use in high-grade TVs and displays. The interlace and crossover distortion responses, in particular, have been greatly improved, allowing excellent picture quality on large size televisions and high precision interlace mode displays.
Also, pulse signals can be used for input signals due to the on-chip sawtooth wave generating circuit and driver circuit. Further, the DC and AC feedback circuits can be formed with these ICs alone, simplifying pattern design of sets and ensuring stable performance, All of the functions in a color TV signal system can be processed by connecting these ICs with Sanyo's single-chip IC LA7670 series (NTSC)and LA7680/85 series (PAL/NTSC) (VIF/SIF, video, chroma, deflection).
The LA7837 has maximum deflection current of 1.8Ap-p, making it appropriate for use in portable to mid-size televisions.
The LA7838 has a maximum deflection current of 2.2Ap-p, so it can be used for large size sets, and can drive from 33 to 37 inches.
