PIXI, 12-Port Programmable Mixed-Signal I/O with

12-Bit ADC, 12-Bit DAC, Analog Switches, and GPIO

General Description

Beneﬁts and Features

● 12 Configurable Mixed-Signal Ports Maximize Design

The MAX11311 integrates a PIXI™, 12-bit, multichannel,

analog-to-digital converter (ADC) and a 12-bit, multichannel,

buffered digital-to-analog converter (DAC) in a single

integrated circuit. This device offers 12 mixed-signal high-

voltage, bipolar ports, which are configurable as an ADC

analog input, a DAC analog output, a general-purpose

input (GPI), a general-purpose output (GPO), or an analog

switch terminal. One internal and two external temperature

sensors track junction and environmental temperature.

Adjacent pairs of ports are configurable as a logic-level

translator for open-drain devices or an analog switch.

Flexibility Across Platforms

• Up to 12 12-Bit ADC Inputs

• Single-Ended, Differential, or Pseudo-Differential

Range Options: 0 to 2.5V, ±5V, 0 to +10V, -10V

to 0V

• Programmable Sample Averaging Per ADC Port

• Unique Voltage Reference for Each ADC PIXI Port

• Up to 12 12-Bit DAC Outputs

• Range Options: ±5V, 0 to +10V, -10V to 0V

• 25mA Current Drive Capability with Overcurrent

Protection

PIXI ports provide highly flexible hardware configuration

for 12-bit mixed-signal applications. The MAX11311 is best

suited for applications that demand a mixture of analog and

digital functions. Each port is individually configurable with

up to four selectable voltage ranges within -10V to +10V.

• Up to 12 General-Purpose Digital I/Os

• 0 to +5V GPI Input Range

• 0 to +2.5V GPI Programmable Threshold Range

• 0 to +10V GPO Programmable Output Range

• Logic-Level Shifting Between Any Two Pins

• 60Ω Analog Switch Between Adjacent PIXI Ports

• Internal/External Temperature Sensors, ±1°C

Accuracy

The MAX11311 allows for the averaging of 2, 4, 8, 16,

32, 64, or 128 ADC samples from each ADC-configured

port to improve noise performance. A DAC-configured

output port can drive up to 25mA. The GPIO ports can be

programmed to user-defined logic levels, and a GPI

coupled with a GPO forms a logic-level translator.

● Adapts to Specific Application Requirements and

Allows for Easy Reconfiguration as System Needs

Change

Internal and external temperature measurements monitor

programmable conditions of minimum and maximum tem-

perature limits, using the interrupt to notify the host if one

or more conditions occur. The temperature measurement

results are made available through the serial interface.

● Configurability of Functions Enables Optimized PCB

Layout

● Reduces BOM Cost with Fewer Components in

Small Footprint

The MAX11311 features an internal, low-noise 2.5V voltage

reference and provides the option to use external voltage

references with separate inputs for the DAC and ADC.

The device uses a 4-wire, 20MHz, SPI-compatible serial

interface, operating from a 5V analog supply and a 1.8V

to 5.0V digital supply. The PIXI port supply voltages operate

from a wide range of -12.0V to +12.0V.

• 25mm 32-Pin TQFN

Ordering Information appears at end of data sheet.

The MAX11311 is available in a 32-pin TQFN, 5mm x 5mm

package or a 48-pin TQFP, 7mm x 7mm package specified

over the -40°C to +105°C temperature range.

Applications

● Base Station RF Power Device Bias Controllers

● System Supervision and Control

● Power-Supply Monitoring

● Industrial Control and Automation

● Control for Optical Components
