MAX11301

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

Flexibility Across Platforms

™

The MAX11301 integrates a PIXI , 12-bit, multichannel,

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

nel, 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.

• 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 MAX11301 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 MAX11301 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 pro-

grammed 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

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

The MAX11301 features an internal, low-noise 2.5V volt-

age reference and provides the option to use external

voltage references with separate inputs for the DAC and

Small Footprint

• 36mm 40-Pin TQFN

• 49mm 48-Pin TQFP

ADC. The MAX11301 uses a 400kHz I C-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 -12.0V to +12.0V.

The MAX11301 is available in a 40-pin TQFN, 6mm x 6mm

package or a 48-pin TQFP, 9mm x 9mm 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
