GENERAL DESCRIPTION
The AD5379 contains 40, 14-bit DACs in one CSPBGA package.
The AD5379 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 voltages of VREF(−) = −3.5 V and VREF(+) = +5 V.
The AD5379 offers guaranteed 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 AD5379 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 interface
standards and can handle clock speeds of up to 50 MHz.
The DAC outputs are updated on reception of new data into the
DAC registers. All the outputs can be updated simultaneously
by taking the LDAC input low. Each channel has a program-
mable 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.
