Page 3: Introduction
The TIA-527 has selectable transimpedances of 1.4 KΩ and 14 KΩ plus a post amplifi er with select- able gains of 1 or 10. Thus the overall responsivity ranges from approximately 1, 000 V/W to 100, 000 V/W at the peak of the detector response curve. -

25 % ( 8 hours) of that of the much higher capacity Lithium types. TTI can supply these batteries if de- sired. Replacement of the battery may be accomplished by removing the four 2-56 Philips fl at head screws that retain the bottom cover of the TIA-527. -
Page 5: Operating Considerations
Operating Considerations The TIA-527 is comprised of two fi ber coupled detectors and two amplifi er stages. The fi rst ampli- fi er is a transimpedance stage which converts the net detector output current to a voltage by passing it through a resistor of 1 400 or 14 000 ohms. Additional amplifi cation is optionally provided by the second stage which also serves to provide 50 ohm drive capability. -
