Sanyo EP58B specifications LA76835A, LA76835NM

I2 C Bus Control Lineup

LA76810 Series

LA76835A

Overview

The LA76810 series are I2C bus controller ICs that support the different TV broadcast formats used worldwide and aim for rationalization of color TV set design, improved manufacturability, and lower total costs.

Single crystal multiformat system that supports the different TV broadcast formats used worldwide. ICs optimal for each individual broadcast standard deployed as a pin-to-pin compatible lineup.

·Multiformat system: LA76818A (YCbCr support), LA76828N (YCbCr and E/W support)

·NTSC system: LA76843N/LA76835A (YCbCr and E/W support), LA76835NM (YCbCr and E/W support)

Adjustment-free VIF/SIF, audio trap/audio bandpass filters

Adjustment-free horizontal resonator system

Simplified SG

Supply voltage: VCC = 5 V/9 V

Package: DIP54S (600mil), QIP80E (14 20) (LA76835NM only)
