Tel: 781/329-4700 World Wide Web Site: http://www.analog.com Fax: 781/326-8703 © Analog Devices, Inc., 2000 Dual 8-Bit 50 MSPS A/D Converter FUNCTIONAL BLOCK DIAGRAM ENCODE AIN 8-BIT ANALOG- TO- DIGITAL CONVERTER 8 +VREF +2 V REF ENCODE AD9058 8-BIT ANALOG- TO- DIGITAL CONVERTER 8 A B –VREF –VREF +VREF AIN QUADRATURE RECEIVER 8 Q 8 I RF LO G G AD9058 90° GENERAL DESCRIPTION The AD9058 combines two independent high performance 8-bit analog-to-digital converters (ADCs) on a single mono- lithic IC. Combined with an optional onboard voltage refer- ence, the AD9058 provides a cost effective alternative for systems requiring two or more ADCs. Dynamic performance (SNR, ENOB) is optimized to provide up to 50 MSPS conversion rates. The unique architecture results in low input capacitance while maintaining high per- formance and low power (<0.5 watt/channel). Digital inputs and outputs are TTL compatible. Performance has been optimized for an analog input of 2 V p-p ( ± 1 V; 0 V to +2 V). Using the onboard +2 V voltage reference, the AD9058 can be set up for unipolar positive operation (0 V to +2 V). This internal voltage reference can drive both ADCs. Commercial (0 °C to +70°C) and military (–55°C to +125°C) temperature range parts are available. Parts are supplied in hermetic 48-lead DIP and 44-lead “J” lead packages.
