You can mix and match 20 ADCs, 20 DACs or 20 high-voltage digital I/O pins in any order using the MAX11300 PIXI. Designers, Maxim notes, often work with application-specific devices that are neither flexible nor easy to program. This configurable 20-channel, -10V to +10V high-voltage mixed-signal data converter suits complex applications requiring multiple mixed-signal operations such as 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 optimise a design. It gives engineers the flexibility to be creative, the company adds.

The MAX11300 PIXI data converter integrates a 12-bit, multichannel, analogue-to-digital converter (ADC); a 12-bit, multichannel, buffered digital-to-analogue converter (DAC); and high-voltage analogue switches and digital I/Os. With its -10V to +10V, high-voltage range, the device handles high-voltage bipolar signals. Each of the 20 mixed-signal I/Os can be uniquely configured for the application, so you can optimise 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.

For fast prototyping there is an evaluation (EV) kit (MAX11300EVKIT#) and peripheral module (MAX11300PMB1), and also a PA Bias Reference Design MAXREFDES39#

In a 40-pin, 6 x 6 mm TQFN package or a 48-pin, 9 x 9 mm TQFP package; specified over the -40 °C to +105 °C temperature range; pricing is from $5.88 (1000)
