Small, for TE cooled detectors

SIP-TO8 series

Transimpedance preamplifier

SIP-TO8 is a series of ultra-small transimpedance, AC or DC coupled preamplifiers. It is designed to operate with either biased or non biased detectors. It is compatible with thermoelectrically cooled detectors in TO8 package. SIP-TO8 is dedicated for OEM applications and requires external heatsink (MHS-2). There is a possibility to adjust gain (devices with a frequency bandwidth up to 100 MHz).
