MAX105ECS+

The MAX105ECS+ is a dual, 6bit 800Msps analogue to digital converter (ADC) with on-chip, wideband input amplifier in 80 pin TQFP package. This ADC is designed to allow high speed, high bandwidth and precise digitizing of in-phase (I) and quadrature (Q) baseband signals. It converts analogue signals of both I and Q components to digital outputs at 800Msps while achieving a signal to noise ratio (SNR) of typically 37dB with an input frequency of 200MHz and an integral nonlinearity (INL) of ±0.2LSB and differential nonlinearity (DNL) of ±0.25LSB. A fully differential comparator design and encoding circuits reduce out of sequence errors and ensure excellent metastable performance of only one error per 10^16 clock cycles. It provides LVDS digital outputs with an internal 6:12 demultiplexer that reduces the output data rate to one-half the sample clock rate and output data is in two's complement format. It is used in VSAT receivers, WLANs and test instrumentation.
