Features • Xignal ™ CT ∑Δ ADC technology • 40-50MSPS sampling rate • Anti-alias filter free Nyquist sample range • Unique Instant Overload Recovery (IOR) • Wide 2.10 VPP input range • 1.2V supply voltage • Integrated precision LC PLL • Serial control via SPI compatible interface Description 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 complexity by using programmable serialized outputs which offer the industry standard LVDS and SLVS modes. Power consumption of only 48mW per channel @ 50MSPS gives a total chip power consumption of 384mW. 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 mm 2, 68 pin package. Key Specification Resolution 12 Bits Conversion Rate 40 to 50 MSPS SNR 69.3 dBFS (typ) @ 50 MSPS fIN = 4.4MHz THD –76.6 dB (typ) @ 50 MSPS fIN = 4.4MHz Per Channel Power 48 mW/ch (typ) @ 50MSPS Total Active Power 385 mW (typ) @ 50MSPS Inter-Channel Isolation >110 dB @ fIN = 4.4MHz Operating Temp. Range -40 to +85 °C Applications • Medical imaging, ultrasound • Industrial ultrasound, such as non-destructive testing • Communications • Battery powered portable systems
