FEATURES  
DESCRIPTION  
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.  
Four Complete Current-to-Voltage Converters  
14-Lead Small Outline Package  
Accurate Gain: 20mV/µA, ±4%  
Low Offset Error: 250nA Max  
Low Offset Drift: 2.5nA/°C Max  
Fast Settling: 145ns to 0.1% for a 2V Step  
Wide Bandwidth: 12MHz  
Low Noise: 5pA/Hz  
Low Quiescent Current: 11mA Max  
Wide Supply Range: ±2V to ±18V or 4V to 36V  
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.
