2. CDS/AGC + 10-bit ADC
The HD49323AF-01 (manufactured by Hitachi) is recommended as an optimal CDS/AGC + 10-bit
ADC IC for the HD49815TF. Since the HD49323AF-01 provides a correlated double sampling circuit
that realizes high S/N and an automatic gain control (AGC) circuit that implements programmable
control of 0 dB to 34.7 dB, it enables a high-image-quality camera system when used in conjunction
with the HD49815TF.
