transimpedance amplifier
Product specification
TZA3023
FEATURES
• Wide dynamic input range from 1 µA to 1.5 mA
• Low equivalent input noise of 3.5 pA/√Hz (typical)
• Differential transimpedance of 21 kΩ
• Wide bandwidth from DC to 600 MHz
• Differential outputs
• On-chip Automatic Gain Control (AGC)
• No external components required
• Single supply voltage from 3.0 to 5.5 V
• Bias voltage for PIN diode
• Pin compatible with SA5223.
APPLICATIONS
• Digital fibre optic receiver in short, medium and long
haul optical telecommunications transmission systems
or in high-speed data networks
• Wideband RF gain block.
DESCRIPTION
The TZA3023 is a low-noise transimpedance amplifier with
AGC designed to be used in STM4/OC12 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.
