Linear Technology LT1311

The LT1311 is ideal for converting multiple photo diode currents to voltages and for general purpose matched inverting amplifier applications. The LT1311 contains four current feedback amplifiers, each with an internal 20k feedback resistor. Only in the most demanding applications will the LT1311 need to be mounted close to the photo diodes.

DESCRIPTION

The LT ®1311 is a quad current-to-voltage converter designed for the demanding requirements of photo diode amplification. A new approach to current-to-voltage conversion provides excellent DC and AC performance without external DC trims or AC frequency compensation. A supply bypass capacitor is the only external component required to convert four signal currents to voltages. Unlike voltage feedback-based current-to-voltage converters that operate with only a specified value of input capacitance, the current feedback LT1311 settles cleanly with any input capacitance up to 50pF. , LTC and LT are registered trademarks of Linear Technology Corporation.
