The MAX1126 quad, 12-bit analog-to-digital converter (ADC) features fully differential inputs, a pipelined architecture, and digital error correction. This ADC is optimized for low-power, high-dynamic performance for medical imaging, communications, and instrumentation applications. The MAX1126 operates from a 1.7V to 1.9V single supply and consumes only 563mW while delivering a 69.9dB signal-to-noise ratio (SNR) at a 5.3MHz input frequency. In addition to low operating power, the MAX1126 features an 813µA power-down mode for idle periods.

An internal 1.24V precision bandgap reference sets the ADC's full-scale range. A flexible reference structure allows the use of an external reference for applications requiring increased accuracy or a different input voltage range.

A single-ended clock controls the conversion process. An internal duty-cycle equalizer allows for wide variations in input-clock duty cycle. An on-chip phase-locked loop (PLL) generates the high-speed serial low-voltage differential signaling (LVDS) clock.

The MAX1126 provides serial LVDS outputs for data, clock, and frame alignment signals. The output data is presented in two's complement or binary format.

Refer to the MAX1127 data sheet for a pin-compatible 65Msps version of the MAX1126.

The MAX1126 is available in a small, 10mm x 10mm x 0.9mm, 68-pin QFN package with exposed paddle and is specified for the extended industrial (-40°C to +85°C) temperature range.

Product Detail

The MAX1127 evaluation kit (EV kit) is a fully assembled and tested circuit board that contains all the components necessary to evaluate the performance of the MAX1126/MAX1127 quad 12-bit analog-to-digital converter (ADC). The MAX1126/MAX1127 accept differential analog input signals. The EV kit generates these signals from user-provided single-ended input sources. The digital outputs produced by the ADC can be easily sampled with a user-provided, high-speed logic analyzer or data-acquisition system. The EV kit also features an on-board deserializer to ease integration with standard logic analysis systems. The EV kit operates from 1.8V and 3.3V power supplies (1.5V for the optional FPGA) and includes circuitry that generates a clock signal from an AC signal provided by the user. The EV kit comes with the MAX1127 installed. Order free samples of the pin-compatible MAX1126 to evaluate this part.
