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 analog-
to-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.
In normal operation, the 0 to 16mA/4–20mA 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 preci-
sion 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 5.25V V/I supply, and a 7V to 30V loop sup-
ply. 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.
