MAX11261ENX+ Product Details

The MAX11261ENX+ 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 MAX11261ENX+ 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 MAX11261ENX+ 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 MAX11261ENX+ 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 MAX11261ENX+ 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.
