® FPO OPT210 MONOLITHIC PHOTODIODE AND AMPLIFIER 300kHz Bandwidth at RF = 1MΩ FEATURES q BOOTSTRAP ANODE DRIVE: Extends Bandwidth: 900kHz (RF = 100KΩ) Reduces Noise q LARGE PHOTODIODE: 0.09" x 0.09" q HIGH RESPONSIVITY: 0.45A/W (650nm) q EXCELLENT SPECTRAL RESPONSE q WIDE SUPPLY RANGE: ±2.25 to ±18V q TRANSPARENT DIP, SIP AND SURFACEMOUNT PACKAGES DESCRIPTION The OPT210 is a photodetector consisting of a high performance silicon photodiode and precision FETinput transimpedance amplifier integrated on a single monolithic chip. Output is an analog voltage proportional to light intensity. The large 0.09" x 0.09" photodiode is operated at low bias voltage for low dark current and excellent linearity. A novel photodiode anode bootstrap circuit reduces the effects of photodiode capacitance to extend bandwidth and reduces noise. The integrated combination of photodiode and transimpedance amplifier on a single chip eliminates the problems commonly encountered with discrete designs such as leakage current errors, noise pick-up and gain peaking due to stray capacitance. The OPT210 operates from ±2.25 to ±18V supplies and quiescent current is only 2mA. Available in a transparent 8-pin DIP, 8-lead surface-mount and 5-pin SIP, it is specified for 0° to 70°C operation.
