Stand-Alone, 4.5-/3.5-Digit Panel Meters with 4–20mA Output
General Description
The MAX1365/MAX1367 low-power, 4.5- and 3.5-digit, panel meters feature an integrated sigma-delta analogto-digital converter (ADC), LED display drivers, voltage digital-to-analog converter (DAC), and a 4–20mA (or 0 to 16mA) current driver. 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 4–20mA (or 0 to 16mA) current-loop output.
