MAX11300

PIXI, 20-Port Programmable Mixed-Signal I/O with

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

General Description

Beneﬁts and Features

● 20 Configurable Mixed-Signal Ports Maximize Design

The MAX11300 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 20 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 20 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 20 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 MAX11300 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 20 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

The MAX11300 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.

•ꢀ 60Ω Analog Switch Between Adjacent PIXI Ports

•ꢀ Internal/External Temperature Sensors, ±1˚C Accuracy

● Adapts to Specific Application Requirements and Allows

for Easy Reconfiguration as System Needs Change

● Configurability of Functions Enables Optimized PCB

Layout

Internal and external temperature measurements monitor

programmable conditions of minimum and maximum

temperature 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.

● Reduces BOM Cost with Fewer Components in

Small Footprint

• 36mm2 40-Pin TQFN

• 49mm2 48-Pin TQFP

The device 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.

Ordering Information appears at end of data sheet.

The MAX11300 is available in a 40-pin TQFN, 6mm x 6mm

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
