AD5748
THEORY OF OPERATION
The AD5748 is a single-channel, precision, voltage/current
output driver with hardware or software programmable
output ranges. The software ranges are configured via an SPI-/
MICROWIRE-compatible serial interface. The analog input
to the AD5748 is provided from a low voltage, single-supply,
digital-to-analog converter and is internally conditioned to
provide the desired output current/voltage range. The analog
input range is 0 V to 4.096 V.
The output current range is programmable across two current
ranges: 4 mA to 21 mA and 0 mA to 21 mA.
The voltage output is provided from a separate pin that can
be configured to provide 0 V to 5 V, 0 V to 10.5 V, or ±10.5 V
output ranges. The current and voltage outputs are available on
separate pins. Only one output can be enabled at one time. The
output range is selected by programming the R3 to R0 bits in
the control register (see Table 6 and Table 7).

Figure 49 and Figure 50 show a typical configuration of the
AD5748 in software mode and in hardware mode, respectively,
in an output module system. The HW SELECT pin selects
whether the part is configured in software or hardware mode.
The analog input to the AD5748 is provided from a low voltage,
single-supply, digital-to-analog converter (DAC) such as the
AD506x or AD566x, which provides an output range of 0 V
to 4.096 V. The supply and reference for the DAC, as well as
the reference for the AD5748, can be supplied from a reference
such as the ADR392. The AD5748 can operate from supplies
up to ±26.4 V.
SOFTWARE MODE
In current mode, software-selectable output ranges include 0 mA
to 21 mA, and 4 mA to 21 mA.
In voltage mode, software-selectable output ranges include 0 V
to 5 V, 0 V to 10.5 V, and ±10.5 V.
