ADC12EU050

Ultra-Low Power, Octal, 12-bit, 40-50 MSPS Sigma-Delta

Analog-to-Digital Converter

General Description

Features

CT∑Δ ADC architecture with 40-50MSPS throughput

Anti-alias filter free Nyquist sample range

Unique Instant Overload Recovery (IOR)

Wide 2.10 V_PPinput range

■

The ADC12EU050 is a 12-bit, ultra-low power, octal A/D con-

verter for use in high performance analog to digital applica-

tions. 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 re-

covery (IOR) with no memory effect guarantees the elimina-

tion of phase errors resulting from out of range input signals.

The ADC12EU050 reduces interconnection complexity by us-

ing 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 con-

sumption 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 mm², 68 pin package.
