LZ34C10

LZ34C10 LZ34C10 DESCRIPTION The LZ34C10 is a 1/4-type (4.5 mm) solid-state color image sensor that consists of PN photodiodes and CMOS (Complementary Metal Oxide Semi-conductor) devices. The sensor further includes a timing generator (TG), a correlated double sampling (CDS) circuit, an auto gain control (AGC) circuit and an analog-to-digital converter (ADC) circuit.
