Maxim Integrated MAX1446

The MAX1446 10-bit, 3V analog-to-digital converter (ADC) features a fully differential input, a pipelined 10stage ADC architecture with digital error correction and wideband track and hold (T/H) incorporating a fully differential signal path. This ADC is optimized for lowpower, 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.

GENERAL DESCRIPTION

FEATURES

o Single 3.0V Operation o Excellent Dynamic Performance 59.5dB SNR at fIN = 20MHz 73dB SFDR at fIN = 20MHz o Low Power: 30mA (Normal Operation) 5µA (Shutdown Mode) o Fully Differential Analog Input o Wide 2Vp-p Differential Input Voltage Range o 400MHz -3dB Input Bandwidth o On-Chip 2.048V Precision Bandgap Reference o CMOS-Compatible Three-State Outputs o 32-Pin TQFP Package MAX1446 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 and the MAX1448 data sheet for a 80Msps version.
