"I'd reduce total system cost and power dissipation, the AD'liluG provides an internal voltage ii'lL-p.-riH ami operates from a single +5 volt power supply. Digit a! outputs are CMOS compatible and rated to 6(1 MSPS conversion rates. The digital input (ENCODE) utilizes a CMOS input stage with a TTL compatible (1.4 V) threshold. The AD9066 is housed in a 28-lead SOIC and a 28-lead SSOP AD9066JR is rated for operation over the 0°C to 70°C commercial temperature range. The ADMooAR/ARS is rated for the 40 C lo +S5 l": iiidiisirijl temperature range. The internal voltage reference insures thai the analog input is biased to midscale with low offset when driven from an ac- coupled source.
