APPLICATIONS • Professional Video • HDTV • Communications • Imaging • Digital Oscilloscopes FEATURES • 10-Bit, 100 MSPS Analog-to-Digital Converter • Monolithic Bipolar • Single-Ended Bipolar Analog Input • -1.0 V to +1.0 V Analog Input Range • Internal Sample-and-Hold • Internal Voltage Reference • Programmable Data Output Formats • Single Ended TTL Outputs • Differential ECL Clock Input GENERAL DESCRIPTION The SPT7871 is a 10-bit, 100 MSPS analog-to-digital con- verter, with a two stage subranging flash/folder architecture. The bipolar, single-ended analog input provides an easy interface for most applications. Programmable data output formats provide additional ease of implementation and flex- ibility. The device supports high speed TTL outputs. The resolution and performance of this device makes it well suited for professional video and HDTV applications. The on- chip track-and-hold provides for excellent AC performance enabling this device to be a converter of choice for RF communications and digital sampling oscilloscopes. The SPT7871 is available in a 44L cerquad package in the industrial temperature range and in die form. |
