Transimpedance Amplifier
Electronic Engineering
WLTA-AG
These modules are composed of a two-stage AC/DC coupled six step adjustable
gain transimpedance amplifier and his stabilized power supply regulator, all
housed in an aluminum body. The device features BNC input/output connectors
and a negative voltage generator to allow bipolar functioning.
Features
• Two-stage amplifier
• Internal supply regulator with negative voltage generator
• Adjustable gain
• AC/DC coupling
Applications
• Photodiode amplifiers
• Synchronous detection
• Smoke detection
• Particle detection
• Distance measurement
