特性
- Suppresses the CCD reset noise by the correlated double sampling.
- High sensitivity can be achieved by 10-bit gray scale provided by PGA which can be set to –6dB to 34dB.
- PGA gain, S/H frequency response, pulse timing, etc., is achieved via a serial interface.
- High precision is provided by a 12-bit resolution A/D converter.
- Difference encoded gray code can be selected as an A/D output code. It is effective in suppression of solarization (wave pattern).
