(excluding reference) • Latch-Up Free • ESD Protection: 2000V Minimum GENERAL DESCRIPTION The XRD8785 is an 8-bit Analog-to-Digital Converter. Designed using an advanced 5V CMOS process, this part offers excellent performance, low power con- sumption, 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 AV DD. 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 V RB to • 20-Pin Package Available: XRD8775 • 3V Version: XRD87L85 APPLICATIONS • Digital Color Copiers • Cellular Telephones • CCDs and Scanners • Video Capture Boards V RBS and VRT to VRTS, or provide external reference voltages to the V RB and VRT pins. The internal reference generates 0.6V at V RB and 2.6 V at VRT. Providing external reference voltages allows easy interface to any input signal range between AGND and AV DD. 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. The device operates from a single +5V supply. Power consumption is 75mW at FS = 15MHz. Specified for operation over the commercial/industrial (–40 to +85°C) temperature range, the XRD8785 is available in Plastic Dual-in-line (PDIP), Surface Mount (SOIC) and Small Outline (SOP) packages in EIAJ and JEDEC.
