Maxim Integrated MAX1449

The MAX1449 +3.3V, 10-bit analog-to-digital converter (ADC) features a fully differential input, a pipelined 10stage ADC architecture with wideband track-and-hold (T/H), and digital error correction incorporating a fully differential signal path. The ADC is optimized for lowpower, high-dynamic performance in imaging and digital communications applications. The converter operates from a single +2.7V to +3.6V supply, consuming only 186mW while delivering a 58.5dB (typ) signalto-noise ratio (SNR) at a 20MHz input frequency.

GENERAL DESCRIPTION

The fully differential input stage has a -3dB 400MHz bandwidth and may be operated with single-ended inputs. In addition to low operating power, the MAX1449 features a 5µA power-down mode for idle periods. An internal +2.048V precision bandgap reference is used to set the ADC’s full-scale range. A flexible reference structure allow’s the user to supply a buffered, direct, or externally derived reference for applications requiring increased accuracy or a different input voltage range. Lower speed, pin-compatible versions of the MAX1449 are also available. Refer to the MAX1444 data sheet for a 40Msps version, the MAX1446 data sheet for a 60Msps version, and the MAX1448 data sheet for 80Msps. The MAX1449 has parallel, offset binary, CMOS-compatible, three-state outputs that can be operated from +1.7V to +3.6V 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) temperatu...
