INTEGRATED CIRCUITS DATA SHEET TDA3810 Spatial, stereo and pseudo-stereo sound circuit Product specification File under Integrated Circuits, IC02 January 1985 Philips Semiconductors Product specification Spatial, stereo and pseudo-stereo sound circuit DESCRIPTION TDA3810 The TDA3810 integrated circuit provides spatial, stereo and pseudo-stereo sound for radio and television equipment. Features · Three switched functions: ­ spatial (widened stereo image) ­ stereo ­ pseudo-stereo (artificial stereo from a mono source) · Offset compensated operational amplifiers to reduce switch noise · LED driver outputs to facilitate indication of selected operating mode · Start/stop circuit to reduce switch noise and to prevent LED-flicker · TTL-compatible control inputs QUICK REFERENCE DATA Supply voltage (pin 18) Supply current (LEDs off) Operating ambient temperature range Input signals (r.m.s. value) Total harmonic distortion (stereo) Channel separation (stereo) Gain (stereo) PACKAGE OUTLINE 18-lead DIL; plastic (SOT102); SOT102-1; 1996 November 25.
