Part Number: AD5378
Function: 32-Channel, 14-Bit, Parallel and Serial Input, Bipolar Voltage Output DAC
Package: CSPBGA Type
Manufacturer: Analog Devices
Pinouts:
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 voltages of VREF(−) = −3.5 V and VREF(+) = +5 V. The AD5378 guarantees operation over a wide VSS/VDDsupply 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.
