Maxim 100MSPS Manuals

The MAX19516 is a 10-bit, dual-channel, 100Msps ADC from ADI that operates from a 2.5V to 3.3V AVDD supply and accepts a wide 0.4V to 1.4V input common-mode voltage range. It supports DC-coupled inputs and can be used in a variety of RF, IF, and baseband front-end applications. The device has a typical signal-to-noise ratio (SNR) performance of 60dBFS and a typical spurious-free dynamic range (SFDR) of 82dBc at fIN = 70MHz and fCLK = 100MHz.

The MAX1198 is a 3.3V, dual, 8-bit analog-to-digital converter (ADC) featuring fully differential wideband track- and-hold (T/H) inputs, driving two ADCs. The MAX1198 is optimized for low power, small size, and high-dynamic performance for applications in imaging, instrumenta- tion, and digital communications. This ADC operates from a single 2.7V to 3.6V supply, consuming only 264mW, while delivering a typical signal-to-noise and distortion (SINAD) of 48.1dB at an input frequency of 50MHz and a sampling rate of 100Msps. The T/H-driven input stages incorporate 400MHz (-3dB) input ampli- fiers. The converters may also be operated with single- ended inputs. In addition to low operating power, the MAX1198 features a 3.2mA sleep mode, as well as a 0.15µA power-down mode to conserve power during idle periods. An internal 2.048V precision bandgap reference sets the full-scale range of the ADC. A flexible reference structure allows the use of this internal or an externally applied reference, if desired, for applications requiring increased accuracy or a different input voltage range. The MAX1198 features parallel, CMOS-compatible three- state outputs. The digital output format can be set to two’s complement or straight offset binary through a single con- trol pin. The device provides for a separate output power supply of 1.7V to 3.6V for flexible interfacing with various logic families. The MAX1198 is available in a 7mm x 7mm, 48-pin TQFP package, and is specifi- ed for automotive and industrial applications.

The MAX19506 is a dual-channel, 8-bit, 100Msps ADC from Texas Instruments. The chip is powered by a 1.8V supply and has excellent dynamic performance and low power consumption.
