MAX1365 - Digit Panel Meters

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.

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 5.25V 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. Features.
  • Stand-Alone, Digital Panel Meter 20-Bit Sigma-Delta ADC 4.5-Digit Resolution (±19,999 Count, MAX1365) 3.5-Digit Resolution (±1999 Count, MAX1367) No Integrating/Au.

www.DataSheet4U.com 19-3889; Rev 1; 1/06 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.
