MAX1427 15-Bit, 80Msps ADC With -79.3dBFS Noise Floor For Baseband Applications

The MAX1427 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 MAX1427 is optimized for multichannel, multimode receivers, which require the ADC to meet very stringent dynamic performance requirements. With a noise floor of -79.3dBFS, the MAX1427 allows for the design of receivers with superior sensitivity.
The MAX1427 achieves two-tone, spurious-free dynamic range (SFDR) of -91dBc for input Tones of 10MHz and 15MHz. Its excellent signal-to-noise ratio (SNR) of 76.1dB and single-tone SFDR performance (SFDR1/SFDR2) of 93.5dBc/94.5dBc at fIN = 15MHz and a sampling rate of 80Msps make this part ideal for high-performance digital receivers.
The MAX1427 operates from an Analog 5V and a digital 3V supply, features a 2.56VP-P full-scale input range, and allows for a sampling speed of up to 80Msps. The input T/H operates with a -1dB full-power bandwidth of 200MHz.
The MAX1427 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 MAX1427 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 (-40C to +85C) temperature range.
Note that IF parts MAX1418 MAX1428 and MAX1430 (see Pin-Compatible Higher/Lower Speed Versions Selection table) are recommended for applications that require high dynamic performance for input frequencies greater than fCLK/3. The MAX1427 is optimized for input frequencies of less than fCLK/3.
