40-Channel 14-Bit Bipolar Voltage-Output D/A Converter

The AD5379 combines 40 DAC channels and 40 output Amplifiers (with gain) in a single 108-ball CSPBGA package. All DACs are monotonic to 14-bits. Each DAC has a maximum output voltage span of 17.5 V. Using reference voltages of -3.5 V and +5 V, this corresponds to an output range of -8.75 V to +8.75 V.
Each channel on the AD5379 has programmable gain and offset Registers By writing to these Registers the user CAN digitally adjust the range and span of each individual DAC thereby facilitating system calibration. Each DAC output is buffered on-chip with respect to an external REFGND input. The DAC outputs CAN also be switched to REFGND via the /CLR pin.
This device has a 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-A7. It also has a 3-wire serial Interface which is compatible with SPI, QSPI, MICROWIRE and DSP Interface standards. A serial daisy-chain mode is provided to facilitate linking of multiple devices in a system. An /LDAC function allows the simultaneous update of all 40 channels.
