Analog Output

Ground

Channel A Analog Output Voltage.

Channel B Analog Output Voltage.

Channel C Analog Output Voltage.

Channel D Analog Output Voltage.

Ground reference for all on-chip circuitry.

Unbuffered reference voltage shared by all channels. Must be decoupled

to GND.

V_REFIN

D_IN

Analog Input

Digital Input

Serial Data Input. Data is clocked into the 16-bit shift register on the

falling edges of SCLK after the fall of SYNC.

Frame synchronization input for the data input. When this pin goes low, it

enables the input shift register and data is transferred on the falling edges

of SCLK. The DAC is updated on the 16th clock cycle unless SYNC is

brought high before the 16th clock, in which case the rising edge of

SYNC acts as an interrupt and the write sequence is ignored by the DAC.

SYNC

SCLK

Digital Input

Serial Clock Input. Data is clocked into the input shift register on the

falling edges of this pin.

Digital Input

Ground

Exposed die attach pad can be connected to ground or left floating.

Soldering the pad to the PCB offers optimal thermal performance and

enhances package self-alignment during reflow.

(SON only)

These devices have limited built-in ESD protection. The leads should be shorted together or the device placed in conductive foam

during storage or handling to prevent electrostatic damage to the MOS gates.

(1) Absolute Maximum Ratings indicate limits beyond which damage to the device may occur. Operating Ratings indicate conditions for

which the device is functional, but do not guarantee specific performance limits. For guaranteed specifications and test conditions, see

the Electrical Characteristics. The guaranteed specifications apply only for the test conditions listed. Some performance characteristics

may degrade when the device is not operated under the listed test conditions. Operation of the device beyond the maximum Operating

Ratings is not recommended.

(2) All voltages are measured with respect to GND = 0V, unless otherwise specified.

(3) If Military/Aerospace specified devices are required, please contact the TI Sales Office/Distributors for availability and specifications.

(4) When the input voltage at any pin exceeds 5.5V or is less than GND, the current at that pin should be limited to 10 mA. The 20 mA

maximum package input current rating limits the number of pins that can safely exceed the power supplies with an input current of 10

mA to two.

(5) The absolute maximum junction temperature (T_Jmax) for this device is 150°C. The maximum allowable power dissipation is dictated by

T_Jmax, the junction-to-ambient thermal resistance (θ_JA), and the ambient temperature (T_A), and can be calculated using the formula

P_DMAX = (T_Jmax − T_A) / θ_JA. The values for maximum power dissipation will be reached only when the device is operated in a severe

fault condition (e.g., when input or output pins are driven beyond the operating ratings, or the power supply polarity is reversed).

(6) Human body model is 100 pF capacitor discharged through a 1.5 kΩ resistor. Machine model is 220 pF discharged through ZERO

Ohms.
