AD5379 FUNCTIONAL DESCRIPTION DAC ARCHITECTURE—GENERAL The AD5379 contains 40 DAC channels and 40 output amplifiers in a single package. The architecture of a single DAC channel consists of a 14-bit resistor-string DAC followed by an output buffer amplifier. The resistor-string ...
Page 19
V FUNCTION BIAS The AD5379 has an on-chip voltage generator that provides a bias voltage of 4.25 V (minimum). The V bypassing and overdriving purposes only not intended to be used as a supply or a reference. If ...
Page 20
AD5379 CALIBRATION The user can perform a system calibration by overwriting the default values in the m and c registers for any individual DAC channel as follows: • Calculate the nominal offset and gain coefficients for the new output range ...
Page 21
FIFO VS. NON-FIFO OPERATION Two modes of operation are available for loading data to the AD5379 registers: operation with FIFO disabled and operation with FIFO enabled. Operation with FIFO disabled is optimum for single writes to the device. If the ...
Page 22
AD5379 INTERFACES The AD5379 contains a serial and a parallel interface. The active interface is selected via the SER/ PAR pin. The AD5379 uses an internal FIFO memory to allow high speed successive writes in both serial and parallel modes. ...
Page 23
Daisy-Chain Mode For systems that contain several DACs, the SDO pin can be used to daisy-chain several devices together. This daisy-chain mode can be useful in system diagnostics and in reducing the number of serial interface lines. Connecting the DCEN ...

AD5379 DATA DECODING The AD5379 contains a 14-bit data bus, DB13 to DB0. Depend- ing on the values of REG1 and REG0, this data is loaded into the addressed DAC input register(s), offset (c) register(s), gain (m) register(s), or the ...
Page 25
ADDRESS DECODING The AD5379 contains an 8-bit address bus A0. This address bus allows each DAC input register (x1), each offset (c) register, and each gain (m) register to be individually updated. Table 17. DAC Group Addressing A7 ...
