    Description

    The MAX1429 is a 5V, high-speed, high-performance analog-to-digital converter (ADC) featuring a fully differential wideband track-and-hold (T/H) and a 15-bit converter core. The MAX1429 is optimized for multichannel, multimode receivers, which require the ADC to meet very stringent dynamic performance requirements. With a noise floor of -77.7dBFS, the MAX1429 allows for the design of receivers with superior sensitivity.

    The MAX1429 achieves two-tone, spurious-free dynamic range (SFDR) of -100dBc for input tones of 10MHz and 15MHz. Its excellent signal-to-noise ratio (SNR) of 75.1dB and single-tone SFDR performance (SFDR1/SFDR2) of 90dBc/94dBc at fIN = 15MHz and a sampling rate of 100Msps make this part ideal for high-performance digital receivers.

    The MAX1429 operates from an analog 5V and a digital 3V supply, features a 2.2VP-P full-scale input range, and allows for a sampling speed of up to 100Msps. The input T/H operates with a -1dB full-power bandwidth of 260MHz.

    The MAX1429 features parallel, CMOS-compatible outputs in two's-complement format. To enable the interface with a wide range of logic devices, this ADC provides a separate output driver power-supply range of 2.3V to 3.5V. The MAX1429 is manufactured in an 8mm x 8mm, 56-pin thin QFN package with exposed paddle (EP) for low thermal resistance, and is specified for the extended industrial (-40°C to +85°C) temperature range.

    Note that IF parts MAX1418, MAX1428, and MAX1430 (see Pin-Compatible Higher/Lower Speed Versions Selection table in the full datasheet) are recommended for applications that require high dynamic performance for input frequencies greater than fCLK/3. The MAX1429 is optimized for input frequencies of less than fCLK/3.
