The MAX1446 10-bit, 3V analog-to-digital converter (ADC) features a fully differential input, a pipelined 10-stage ADC architecture with digital error correction and wideband track and hold (T/H) incorporating a fully differential signal path. This ADC is optimized for low-power, high dynamic performance applications in imaging and digital communications. The MAX1446 operates from a single 2.7V to 3.6V supply, consuming only 90mW while delivering a 59.5dB signal-to-noise ratio (SNR) at a 20MHz input frequency. The fully differential input stage has a 400MHz, -3dB bandwidth and may be operated with single-ended inputs. In addition to low operating power, the MAX1446 features a 5µA power-down mode for idle periods.

An internal 2.048V precision bandgap reference is used to set the ADC full-scale range. A flexible reference structure allows the user to supply a buffered, direct or externally derived reference for applications requiring increased accuracy or a different input voltage range.

Lower and higher speed, pin-compatible versions of the MAX1446 are also available. Refer to the MAX1444 data sheet for a 40Msps version, the MAX1448 datasheet for an 80Msps version, and the MAX1449 datasheet for a 105Msps version.

The MAX1446 has parallel, offset binary, three-state outputs that can be operated from 1.7V to 3.3V to allow flexible interfacing. The device is available in a 5mm x 5mm, 32-pin TQFP package and is specified over the extended industrial (-40°C to +85°C) and automotive (-40°C to+105°C) temperature ranges.

Product Detail

The MAX1448 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX1444, MAX1446, MAX1448, or MAX1449 10-bit analog-to-digital converters (ADCs). The MAX1444/MAX1446/MAX1448/MAX1449 ADCs process differential or single-ended analog inputs. The EV kit allows the user to evaluate the ADCs with both types of signals from one single-ended analog signal. The digital output produced by the ADCs can be easily sampled with a user-provided high-speed logic analyzer or data-acquisition system. The EV kit comes with the MAX1448 installed. Order free samples of the MAX1444EHJ, MAX1446EHJ or MAX1449EHJ to evaluate these parts. The EV kit operates from a +3V power supply. It includes circuitry that generates a clock signal from an AC signal provided by the user.

Applications

  • Baseband and IF Digitization
  • CCD Imaging
  • Digital Television (Receivers, Set-Top Boxes)
  • Ultrasound Imaging
  • Video Digitizing Applications
