S7998 is a UV to near IR detector using a 3 × 3 mm photodiode integrated with preamplifier. The photodiode chip and the preamplifier are
assembled at high density by direct bump connections. The preamplifier bias current is so small that a high feedback resistance of 1 G
can be
used. Built-in feedback resistance types and metal package types are also available upon request.
Features
l Compact ceramic package: 13.2 × 7.37 mm
l Uses a UV to near IR Si photodiode (3 × 3 mm)
for high-precision photometry
l Uses a low bias current preamplifier: Ib=64 pA Max.
l Low noise
l Low current consumption
Applications
l Precision photometry
l General photometry
