APPLICATIONS INFORMATION
TYPICAL APPLICATION CIRCUITS
The AD5346/AD5347/AD5348 can be used with a wide range
of reference voltages, especially if the reference inputs are
configured as unbuffered, in which case the devices offer full,
one-quadrant multiplying capability over a reference range of
0.25 V to VDD. More typically, these devices may be used with a
fixed, precision reference voltage. Figure 41 shows a typical
setup for the devices when using an external reference
connected to the reference inputs. Suitable references for 5 V
operation are the AD780, ADR381, and REF192 (2.5 V refer-
ences). For 2.5 V operation, suitable external references are the
AD589 and the AD1580 (1.2 V band gap references).

Figure 41. AD5346/AD5347/AD5348 Using an External Reference
DRIVING VDD FROM THE REFERENCE VOLTAGE
If an output range of 0 V to VDD is required, the simplest
solution is to connect the reference inputs to VDD. Because this
supply may not be very accurate and may be noisy, the devices
can be powered from the reference voltage, for example, by
using a 5 V reference such as the ADM663 or ADM666, as
shown in Figure 42.

BIPOLAR OPERATION USING THE
AD5346/AD5347/AD5348
The AD5346/AD5347/AD5348 have been designed for single-
supply operation, but a bipolar output range is also possible by
using the circuit shown in Figure 43. This circuit has an output
voltage range of ±5 V. Rail-to-rail operation at the amplifier
output is achievable using an AD820, an AD8519, or an OP196
as the output amplifier.

Figure 43. Bipolar Operation with the AD5346/ AD5347/AD5348
The output voltage for any input code can be calculated as
follows:
VOUT
= [(1 + R4/R3) × (R2/(R1 + R2) × (2 × VREF × D/2N)] –
R4
× VREF/R3
where:
D
is the decimal equivalent of the code loaded to the DAC.
N
is the DAC resolution.
VREF
is the reference voltage input.
