XRD8785 CCD Image Digitizers with CDS, PGA and 12-Bit A/D
The XRD8785 is an 8-bit Analog-to-Digital Converter. Designed using an advanced 5V CMOS process, this part offers excellent performance, low power consumption and latch-up free operation. This device uses a two-step flash architecture to maintain low power consumption at high conversion rates. The input circuitry of the XRD8785 includes an on-chip S/H function which allows the user to digitize analog input signals between AGND and AVDD. Careful design and chip layout have achieved a low analog input capacitance. This reduces "kickback" and eases the requirements of the buffer/amplifier used to drive the XRD8785. The designer can choose the internally generated reference voltages by connecting VRB to VRBS and VRT to VRTS, or provide external reference voltages to the VRB and VRT pins. The internal reference generates 0.6 V at VRB and 2.6 V at VRT. Providing external reference voltages allows easy interface to any input signal range between AGND and AVDD. This also allows the system to adjust these voltages to cancel zero scale and full scale errors, or to change the input range as needed
