NXP Semiconductors TDA3810
The TDA3810 integrated circuit provides spatial, stereo and pseudo-stereo sound for radio and television equipment.DESCRIPTION
TDA3810FEATURES
● 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.
