ORDERING INFORMATION TYPE NUMBER TZA3033T TZA3033U PACKAGE NAME SO8 naked die DESCRIPTION plastic small outline package; 8 leads; body width 3.9 mm die in waffle pack carriers; die dimensions 0.960 × 1.210 mm APPLICATIONS TZA3033 Digital fibre optic receiver in short, medium and long haul optical telecommunications transmission systems or in high speed data networks Wideband RF gain block. GENERAL DESCRIPTION The TZA3033 is a low-noise transimpedance amplifier with AGC designed to be used in STM1/OC3 fibre optic links. It amplifies the current generated by a photo detector (PIN diode or avalanche photodiode) and converts it to a differential output voltage.
