Description

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.
