The LT
1311 is a quad current-to-voltage converter de-
signed for the demanding requirements of photo diode
amplification. A new approach to current-to-voltage con-
version provides excellent DC and AC performance with-
out external DC trims or AC frequency compensation. The
LT1311 is ideal for converting multiple photo diode cur-
rents to voltages and for general purpose matched invert-
ing amplifier applications.
The LT1311 contains four current feedback amplifiers,
each with an internal 20k feedback resistor. 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 oper-
ate with only a specified value of input capacitance, the
current feedback LT1311 settles cleanly with any input
capacitance up to 50pF. Only in the most demanding
applications will the LT1311 need to be mounted close to
the photo diodes.
