В® OPT301 FPO
70% INTEGRATED PHOTODIODE
AND AMPLIFIER
FEATURES DESCRIPTION в—Џ PHOTODIODE SIZE: 0.090 x 0.090 inch
(2.29 x 2.29mm) The OPT301 is an opto-electronic integrated circuit
containing a photodiode and transimpedance
amplifier on a single dielectrically isolated chip. The
transimpedance amplifier consists of a precision FETinput op amp and an on-chip metal film resistor. The
0.09 x 0.09 inch photodiode is operated at zero bias for
excellent linearity and low dark current. ● 1MΩ FEEDBACK RESISTOR
в—Џ HIGH RESPONSIVITY: 0.47A/W (650nm)
в—Џ IMPROVED UV RESPONSE
в—Џ LOW DARK ERRORS: 2mV
в—Џ BANDWIDTH: 4kHz
в—Џ WIDE SUPPLY RANGE: В±2.25 to В±18V The integrated combination of photodiode and
transimpedance amplifier on a single chip eliminates
the problems commonly encountered in discrete designs such as leakage current errors, noise pick-up and
gain peaking due to stray capacitance. в—Џ LOW QUIESCENT CURRENT: 400ВµA
в—Џ HERMETIC TO-99 The OPT301 operates over a wide supply range (В±2.25
to В±18V) and supply current is only 400ВµA. It is
packaged in a hermetic TO-99 metal package with a
glass window, and is specified for the –40°C to 85°C
temperature range. APPLICATIONS …
