Description :
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.
