TSH340 320MHz Single Supply Video Buffer with Low In/Out Rail Bandwidth: 320MHz Pin Connections (top view) Single supply operation down to 3V Low input & output rail Very low harmonic distortion OUOUTT 11 55 +VCC+VCC Slew rate: 780V/s GNGNDD 22 Voltage input noise: 7nV/Hz Specified for 150 and 100 loads ININ 33 44 NCNC Internal gain of 6dB SOSOT2T23-53-5 Compatible with the PCB layout of a single op-amp Tested on 5V power supply Data min. and max. are tested during production NCNC Description NCNC 11 88 The TSH340 is a single supply video buffer NCNC 22 77 +Vcc+Vcc featuring an internal gain of 6dB and a large 33 66 OUOUTT ININ bandwidth of 320MHz for only 9.8mA of quiescent current. GNGNDD 44 55 NCNC An advantage of this circuit is its input and output SO8SO8 negative rail feature, which is very close to GND in single supply. This rail is tested and guaranteed during production at 60mV maximum from GND Applications on a 150 load. This allows a good output swing which fits perfectly when driving a video signal on High-end video systems a 75 video line. Chapter 5 of this datasheet High Definition TV (HDTV) gives technical support when using the TSH340 Broadcast and graphic video as a driver for video DAC output on a video line. In Multimedia products particular, this chapter focuses on applying a video signal DC shift to avoid any clamping of the synchronization tip. The TSH340 is available in tiny SOT23-5 and SO8 plastic packages.
