MAX105
Description
The MAX105 is a dual, 6-bit, analog-to-digital converter (ADC) designed to allow fast and precise digitizing of in-phase (I) and quadrature (Q) baseband signals. The MAX105 converts the analog signals of both I and Q ponents to digital outputs at 800Msps while achieving a signal-to-noise ratio (SNR) of typically 37d B with an input frequency of 200MHz, and an integral nonlinearity (INL) and differential nonlinearity (DNL) of ±0.25 LSB. The MAX105 analog input preamplifiers feature a 400MHz, -0.5d B, and a 1.5GHz, -3d B analog input bandwidth. Matching channel-to-channel performance is typically 0.04d B gain, 0.1LSB offset, and 0.2 degrees phase. Dynamic performance is 36.4d B signal-to-noise plus distortion (SINAD) with a 200MHz analog input signal and a sampling speed of 800MHz. A fully differential parator design and encoding circuits reduce out-of-sequence errors, and ensure excellent metastable performance of only one error per 1016 clock cycles. In addition, the MAX105...
