Bipolar Mode
Set EN_BPM high to engage bipolar operation. In bipo-
lar mode, the current output at 4–20OUT (4–20mA or
0 to 16mA) maps the analog input voltage (±2V or
±200mV). In bipolar mode, a 0V analog input maps to
midscale (12mA). See Table 5 for current output (see
Figures 12 and 13).
5.2V Linear Regulator with Compensation
The MAX1365/MAX1367 feature a 5.2V linear regulator.
The 5.2V regulator consists of an op amp and connec-
tions to an external depletion-mode FET. The 5.2V regu-
lator regulates the loop voltage that powers the
voltage-to-current converter and the rest of the trans-
mitter circuitry. The regulator output voltage is available
at REG_VDD and is given by the equation:
V REG_VDD = 2.54 x V REF+
The FET breakdown and saturation voltages determine
the usable range of loop voltages (V EXT ). The external
FET parameters such as V GS (off), I DSS , and transcon-
ductance must be chosen so that the op amp output on
the REG_FORCE pin can control the FET operating
point while swinging in the range from VREG_AMP to
REG_VDD. See the Selecting Depletion-Mode FET sec-
tion in the Applications Information section.
Connect a 0.1μF capacitor between CMP and
REG_FORCE to ensure stable operation of the regulator.
Applications Information
Power-On Reset
At power-on, the digital filter and modulator circuits
reset. The MAX1365 allows 6s for the reference to sta-
bilize before performing enhanced offset calibration.
