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.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. This is a stress rating only; functional operation of the device at these or any other conditions above those listed in the operational sections of this specification is not implied. Exposure to absolute maximum rating conditions for extended periods may affect device reliability. Only one absolute maximum rating may be applied at any one time.
