The MAX22007 is a software-configurable four-channel analog output device that drives a voltage or current output on each channel. All outputs are protected to ±42VP-P for high-voltage supply of HVDD = 8V to 20V and HVSS = -2V to 0V.

Each output channel of the MAX22007 features a 12-bit DAC with fast settling time using a shared internal voltage reference. The device offers low-offset, high-voltage amplifiers to condition the signal from low-voltage DAC outputs to high-voltage or current outputs. If one output is miswired, all other outputs remain unaffected and function normally. For each channel, an internal comparator can be used to determine the load impedance and allows the microcontroller to intelligently select for voltage or current output mode. All outputs are kept safe by integrated current protection for functional and thermal robustness. The MAX22007 also includes a thermal shutdown circuit that protects the device when the junction temperature exceeds 165°C (typ).

The MAX22007 communicates with a microcontroller using a SPI interface at clock rates up to 30MHz with an optional eight-bit CRC for improved data integrity. Eight GPIOs can be used to interface and control other resources in the application circuit. The MAX22007 operates from a 2.7V to 5.5V VDD low-voltage supply and an 8V to 24V HVDD positive high-voltage supply. The negative voltage supply HVSS can be set between -2V and 0V.

The MAX22007 is available in an 8mm x 8mm 56-pin TQFN package and operates over the -40°C to +85°C temperature range with 2.5kV HBM ESD protection on all pins.

Product Detail

The MAX22007 evaluation kit (EV kit) provides the hard- ware and software necessary to evaluate the MAX22007 Industrial Four-Channel Configurable Analog Output. The MAX22007 EV kit communicates with a graphical user interface (GUI) running on a PC through a USB port. The EV kit provides the on-board FT2232 USB-to-SPI bridge for SPI communication, but also allows an external SPI master to communicate with the MAX22007 through the PMOD1 connector. The onboard DC-DC converters generate necessary supply voltages, +15V for HVDD, +3.3V for VDD, and -2V for HVSS to power the MAX22007.

Multiple MAX22007 EV kit boards can be connected in daisy-chain mode using PMOD1 and PMOD2 connectors.

Applications

  • Building Automation Analog Outputs
  • Configurable Analog Output Cards
  • Factory Automation Analog Outputs
  • Process Automation
  • Programmable Logic Controllers

Product Detail

The MAX22007 Peripheral Module (MAX22007PMB#) provides the hardware to evaluate the MAX22007 fourchannel 12-bit configurable analog output. Refer to the MAX22007 IC data sheet for detailed information regarding operation of the IC.

This module can be used in various ways, but it is primarily configured through SPI. Analog Devices sells low-cost USB2PMB2# and USB2GPIO# adapter boards that use the Munich GUI software for communication through a USB cable. The adapter boards are not included with the MAX22007PMB# board. Alternatively, any microcontroller or FPGA with a 12-pin Pmod™-compatible connector can be used with the SPI connection from the Pmod connector J1. Another option for the user is to wire-wrap a temporary connection from their system to the pins on the connector J1. For these later two options, the user needs to write their own control software. The board dimensions are 3.5” x 0.8” (8.69cm x 2.18cm).
