TDA4481-D Rev. A1 is a sound processor for mono TV sets. It has high signal sensitivity, high signal to noise ratio, easy alignment of multistandard filters, converter for different intercarrier frequencies, AF output level matched to SIMAVELEC condition, few external components, alignment free AM demodulator for standard L, standardized SCART interface, Standard-, SCART- and Mute-switch, TTL compatible AF attenuator, ESD protected, Case: 20-pin dual inline plastic.
The TDA4481-D is a multistandard quasi parallel‑sound processor designed for mono TV sets. It integrates high‑sensitivity audio input, AM/ FM demodulation, and a selectable intercarrier converter, all in a 20‑pin DIP package.
Key features include a high signal‑to‑noise ratio, few external components, a standardized SCART interface, and TTL‑compatible switching for standard, SCART and mute functions. The datasheet lists absolute maximum ratings, detailed pin functions, and electrical characteristics such as supply voltage, current consumption, and temperature limits.
