GENERAL DESCRIPTION
The AD5378 contains 32 14-bit DACs in one CSPBGA package.
The AD5378 provides a bipolar output range determined by the
voltages applied to the VREF(+) and VREF() inputs. The maximum
output voltage span is 17.5 V, corresponding to a bipolar output
range of 8.75 V to +8.75 V, and is achieved with reference volt-
ages of VREF() = 3.5 V and VREF(+) = +5 V.
The AD5378 guarantees operation over a wide VSS/VDD supply
range from ±11.4 V to ±16.5 V. The output amplifier headroom
requirement is 2.5 V operating with a load current of 1.5 mA,
and 2 V operating with a load current of 0.5 mA.
The AD5378 contains a double-buffered parallel interface in
which 14 data bits are loaded into one of the input registers
under the control of the WR, CS, and DAC channel address
pins, A0 to A7. It also has a 3-wire serial interface, which is
compatible with SPI, QSPI, MICROWIRE, and DSP inter-
face standards and can handle clock speeds of up to 50 MHz.
The DAC outputs are updated when the DAC registers receive
new data. All the outputs can be updated simultaneously by
taking the LDAC input low. Each channel has a programmable
gain and an offset adjust register.
Each DAC output is gained and buffered on-chip with respect
to an external REFGND input. The DAC outputs can also be
switched to REFGND via the CLR pin. Table 1 and Table 2
show the product portfolio for high channel count bipolar and
unipolar voltage output DACs.
