STV5728 4-HEAD VIDEO AND 2-HEADS HIFI AUDIO PLAYBACK AND RECORD AMPLIFIER FOR VCR ONE 5V POWER SUPPLY PLAYBACK/RECORD MODE SELECTION THROUGH A LOGIC INPUT PINNING COMPATIBLE WITH STV5725 AND STV5727 SO28 PACKAGE PLAYBACK MODE LOW NOISE AND WIDE BAND AMPLIFIERS FOR 4 VIDEO HEADS AUTOMATIC OFFSET CANCELLATION BETWEEN THE 2 SELECTED HEADS ONE PLAYBACK OUTPUT WITH AGC ONE PLAYBACK OUTPUT (60dB CONSTANT GAIN) ONE OUTPUT FOR AUTOMATIC VIDEO TRACKING SP/LP ENVELOPE COMPARATOR OUTPUT LOW NOISE AMPLIFIERS FOR 2 HIFI HEADS HIFI OUTPUT GAIN (70dB) RECORD MODE TRANSCONDUCTANCE AMPLIFIER VIDEO AGC AMPLIFIER FOR HIFI voltage between the two selected heads is automatically cancelled after 32 switching head cycles. A constant output signal will be available on Pin YPB thanks to an AGC function (Automatic Gain Control). The time constant of the AGC is determined by the capacitor value connected to CAGC Pin. For Automatic Tracking, a signal which is a function of the selected input signal amplitude is present on Pin TRIV. For Trick Mode, a signal resulting from the comparison of the input signal amplitude is available on ENVC Pin. SO28 (Plastic Package) ORDER CODE : STV5728 FOR PIN CONNECTIONS H1SP 1 28 SWR DESCRIPTION STV5728 is intended for 4 heads VCR applications with HIFI. It includes all the electrical functions necessaryto achieveplay-back and record processing. Record or PlaybackMode can be selected through SWR Pin. SWH allows to select the video head input (H1SP or H2SP, H1LP or H2LP), while SWM will select the mode SP or LP. The SWFMH will select the FM input heads in Playbackand will mute the HIFI record amplifier in Record Mode.

Special care has been taken to speed up commutation from Playback to Record and from Record to Playback, avoiding spikes through the loads (the rotary transformers). The recording current level in LP mode is 0.9 time the value of SP one. Playback Mode (FM HIFI) Signals applied on H1FM and H2FM input Pins will be amplified by 70dB voltage gain. IOUTFM Pin is 2/11 AC short-circuited to ground by CCOM1. The input signal can be selected through SWFMH input and the correspondingoutput signal will be available on Pin FMPB. Record Mode (HIFI) The current input applied on FMRIN Pin is amplified through an Automatic Gain Control amplifier. The recording level can be adjusted thanks to the RADJ resistance connected to TRIV Pin. Special care has beentaken to speedup commutationfromPlayback to Record and from Record to Playback, avoiding spikes through the loads (the rotary transformers). 5728-02.EPS HIFI HEADS STV5728 ABSOLUTE MAXIMUM RATINGS Parameter Value Unit V CC Power Supply Voltage 6 Tj Junction Temperature 150 o 0, +70 o Toper Operating Temperature V C C 5728-01.TBL Symbol Symbol Rth (j-a) Parameter Value Junction-ambient Thermal Resistance (IC solded on the PC board) Max.
