Photosensor with front-end IC


Built-in gain-stabilized APD suitable for short pulse light detection

This device is for direct TOF (time-of-flight) distance measurement, integrating a Si APD and a transimpedance amplifier. A gain-stabilized APD (GS APD) is used, and there is little gain fluctuation relative to temperature fluctuation, so there is no need for a temperature sensor or microcontroller. It has an increased high-band cutoff frequency (S16429-01CT: 300 MHz) of the transimpedance amplifier compared to previous products, realizing high-speed response.


- Stable gain against temperature fluctuations
- No gain adjustment according to individual differences required
- Built-in high-speed transimpedance amplifier: 300 MHz
- Low noise
- No ringing
