Transimpedance amplifier

The pda-700 photodiode transimpedance amplifier provides a direct digital readout of the current generated from a photodiode, photomultiplier, or other source of current. The device offers an input range of 20 nA to 2 mA, with a noise level of less than 1 pA. Digitally selectable at front panel controls are an amps/watt calibration factor and a variable bias voltage of +10V to -10V. The instrument also features background cancellation, battery or line operation, lcd display, led backlight for dark lab operation, and analog output of a 2V signal proportional to a maximum display reading of 20,000 counts.
