The MAX19527 is an octal, 12-bit analog-to-digital converter (ADC), optimized for the low-power and high-dynamic performance requirements of medical imaging instrumentation and digital communications applications. The device operates from a single 1.8V supply and consumes 440mW (55mW per channel), while providing a 69dBFS signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the device features programmable power management for idle states and reduced-channel operation.

An internal 1.25V precision bandgap reference sets the full-scale range of the ADC to 1.5VP-P. A flexible reference structure allows the use of an external reference for applications requiring greater gain accuracy or a different input voltage range. A programmable common-mode voltage reference output is provided to enable DC-coupled input applications.

Various adjustments and feature selections are available through programmable registers that are accessed through the 3-wire serial peripheral interface (SPI™).

A flexible clock input circuit allows for a single-ended, logic-level clock or a differential clock signal. An on-chip PLL generates the multiplied (6x) clock required for the serial LVDS digital outputs. The serial LVDS output provides programmable test patterns for data timing alignment and output drivers with programmable current drive and programmable internal termination.

The device is available in a small, 10mm x 10mm x 1.2mm, 144-lead thin chip ball grid array (CTBGA) package and is specified for the extended industrial (-40°C to +85°C) temperature range.

Product Detail

The MAX19527 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX19527 50Msps octal, 12-bit analog-to-digital converter (ADC). The EV kit also includes Windows® 2000-, Windows XP®-, and Windows Vista®-compatible software that provides a simple graphical user interface (GUI) for exercising the features of the ADC.

The EV kit accepts single-ended analog inputs from an analog signal source and provides an on-board circuit that transforms the analog single-ended signal into a differential signal. The ADC digital LVDS outputs can be captured easily with Maxim's data converter evaluation platform (DCEP). The EV kit operates from a single 3.3V power supply and provides on-board regulation for the analog, digital, and logic circuitries.
