Designers often work with application-specific devices that are neither flexible nor easy to program. The MAX11300 PIXI is the industry's first configurable 20-channel, -10V to +10V high-voltage mixed-signal data converter. It is ideally suited for complex applications requiring multiple mixed-signal operations like base stations and industrial control and automation.
Graphical user interface software that comes with the MAX11300 PIXI allows rapid drag and drop configuration of the device. Any function can be assigned to any pin. Select an ADC and connect it to any of 20 pins, select a DAC and connect it to any pin or assign a digital I/O to any pin. Unlike traditional multichannel data converters, the MAX11300 data converter lets engineers configure the 20 mixed signal input/outputs (I/Os) to optimize a design. It gives engineers the flexibility to be creative.
High integration provides a smaller size, lower cost, and simplified bill of materials (BOM). The flexibility of the MAX11300PIXI significantly shortens design time and time to market. The MAX11300 PIXI data converter integrates a 12-bit, multichannel, analog-to-digital converter (ADC); a 12-bit, multichannel, buffered digital-to-analog converter (DAC); and high-voltage analog switches and digital I/Os.
With its wide -10V to +10V, high-voltage range, the MAX11300 PIXI enables high-voltage bipolar signals. It provides more design flexibility than any competing data converter. Each of the 20 mixed-signal I/Os can be uniquely configured for the application, so designers can optimize PCB layout. Configuration software enables simple "drag and drop" setup of the 20 ports. Files can be exported for coding and easily reconfigured as requirements change.
Features:
－ Highly configurable: each of the 20 mixed-signal I/Os can be uniquely configured to optimize the PCB layout.
－ Highly Integrated: 12-bit ADC, 12-bit high-voltage DAC, 20 digital I/Os, and high-voltage analog switching between adjacent ports; enables bipolar input/output voltages; reduces board size and cost.
－ Highly flexible: high-voltage options, 0V to +10V, 0 to 2.5V, +/-5V, -10V to 0V.
－ Easy to use: configuration software enables drag-and-drop configurations with a simple graphical user interface (GUI); no prior programming/coding skills are required.
－ Fast prototyping: an evaluation (EV) kit (MAX11300EVKIT#) and peripheral module (MAX11300PMB1) are available plus a PA Bias Reference Design
