| MAX109 EVAALVUAAILTAIOBNLEKIT 8-Bit, 2.2Gsps ADC with Track/Hold Amplifier and 1:4 Demultiplexed LVDS Outputs The MAX109, 2.2Gsps, 8-bit, analog-to-digital converter ADC enables the accurate digitizing of analog signals with frequencies up to 2.5GHz. Fabricated on an advanced SiGe process, the MAX109 integrates a highperformance track/hold T/H amplifier, a quantizer, and a 1:4 demultiplexer on a single monolithic die. The MAX109 also features adjustable offset, full-scale voltage via REFIN , and sampling instance allowing multiple ADCs to be interleaved in time. The innovative design of the internal T/H amplifier, which has a wide 2.8GHz full-power bandwidth, enables a flat-frequency response through the second Nyquist region. This results in excellent ENOB performance of bits. A fully differential comparator design and decoding circuitry reduce out-of-sequence code errors thermometer bubbles or sparkle codes and provide excellent metastability performance 1014 clock cycles . This design guarantees no missing codes. The analog input is designed for both differential and single-ended use with a 500mVP-P input-voltage range. The output data is in standard LVDS format, and is demultiplexed by an internal 1:4 demultiplexer. The LVDS outputs operate from a supply-voltage range of 3V to 3.6V for compatibility with single 3V-reference systems. Control inputs are provided for interleaving additional MAX109 devices to increase the effective system-sampling rate. The MAX109 is offered in a 256-pin Super Ball-Grid Array SBGA package and is specified over the extended industrial temperature range -40°C to +85°C .
