The MAX1365/MAX1367's analog input voltage range is programmable to either ±2V or ±200mV. The MAX1367 drives a 3.5-digit (±1999 count) display and the MAX1365 drives a 4.5-digit (±19,999 count) display. The ADC output directly drives the LED display as well as the voltage DAC, which in turn drives the 420mA (or 0 to 16mA) current-loop output.
In normal operation, the 0 to 16mA/420mA current-loop output follows the ±2V or ±200mV analog input to drive remote panel-meter displays, data loggers, and other industrial controllers. For added flexibility, the MAX1365/MAX1367 allow direct access to the DAC output and the V/I converter input.
The sigma-delta ADC does not require external precision integrating capacitors, autozero capacitors, crystal oscillators, charge pumps, or other circuitry commonly required in dual-slope ADC panel-meter circuits. On-chip analog input and reference buffers allow direct interface with high-impedance signal sources. Excellent common-mode rejection and digital filtering provide greater than 100dB rejection of simultaneous 50Hz and 60Hz line noise. Other features include data hold, peak detection, and overrange/underrange detection.
The MAX1365/MAX1367 require a 2.7V to 5.25V supply, a 4.75V to 5.75V V/I supply, and a 7V to 30V loop supply. They are available in a space-saving (7mm x 7mm), 48-pin TQFP package and operate over the extended (-40°C to +85°C) temperature range.
