Description

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, instrumentation, 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 amplifiers. 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 control 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 specified for the extended industrial (-40°C to +85°C) temperature range. See a parametric table of the complete family of pin-compatible, 8-bit high-speed ADCs. For a 10-bit, pin-compatible upgrade, refer to the MAX1180 data sheet. With the N.C. pins of the MAX1198 internally pulled down to ground, this ADC becomes a drop-in replacement for the MAX1180.
