Description

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 high-performance 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 6.9 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 500mV_P-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).
