ADC12EU050 Datasheet | National Semiconductor

Description NOTE: This is Advance Information for a product currently in development. ALL specifications are design targets and are subject to change. The ADC12EU050 is a 12-bit, ultra-low power, octal A/D converter for use in high performance analog to digital applications. The ADC12EU050 uses an innovative continuous time sigma delta architecture offering ultra low power consumption and an alias free sample bandwidth up to 25MHz. The input stage of each channel features a proprietary system to ensure instantaneous recovery from overdrive. Instant overload recovery (IOR) with no memory effect guarantees the elimination of phase errors resulting from out of range input signals. The ADC12EU050 reduces interconnection plexity by using programmable serialized outputs which offer the industry standard LVDS and SLVS modes. Power consumption of only 44m W per channel(@ 50MSPS) gives a total chip power consumption of 350m W. The ADC12EU050 can operate entirely from a 1.2V supply, although a separate output driver supply of up to 1.8V can be used. The device operates from -40 to +85 °C and is supplied in a 10 x 10 mm2, 68 pin package.
