PHOTODIODE
WITH ON-CHIP AMPLIFIER
FEATURES
DESCRIPTION
q BANDWIDTH: 50kHz
q PHOTODIODE SIZE: 0.090 x 0.090 inch
(2.29 x 2.29mm)
q 1MΩ FEEDBACK RESISTOR
q HIGH RESPONSIVITY: 0.45A/W (650nm)
The OPT202 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.
q LOW DARK ERRORS: 2mV
q WIDE SUPPLY RANGE: ±2.25 to ±18V
q LOW QUIESCENT CURRENT: 400µA
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.
q TRANSPARENT 8-PIN DIP AND 5-PIN SIP
q HERMETIC 8-PIN CERAMIC DIP
The OPT202 operates over a wide supply range (±2.25
to ±18V) and supply current is only 400µA. It is
packaged in a transparent plastic 8-pin DIP or 5-pin
SIP, specified for the 0°C to +70°C temperature range
as well as a hermetic ceramic 8-pin DIP with a glass
window, specified for the –40°C to +85°C temperature range.
APPLICATIONS
q MEDICAL INSTRUMENTATION
q LABORATORY INSTRUMENTATION
q POSITION AND PROXIMITY SENSORS
q PHOTOGRAPHIC ANALYZERS
q SMOKE DETECTORS
