2. Key Features & Technical Specifications (Partial List – See Notes at End):

️· Linearity Error (INL): Measures deviation from an ideal linear output.
️· Differential Nonlinearity (DNL): Measures variation in output for each digital step.
️· Monotonicity: The ability of the output to consistently increase or remain constant with digital input.
️· Offset Error: Deviation from zero output when all digital inputs are zero.
️· Gain Error: Difference between actual and ideal output span.
️· Output Compliance Range: Voltage limits for DAC output.
️· Temperature Drift: How performance changes with temperature.
️· Power Supply Rejection: How much the output is affected by power supply fluctuations.
️· Settling Time: Time to reach a stable output.
️· Glitch Impulse: Measures unwanted output transients.
️· Spurious-Free Dynamic Range (SFDR): A measure of signal purity (how much noise and unwanted signals are present).
️· Total Harmonic Distortion (THD): A measure of harmonic distortion in the output signal.

3. Pin Configuration & Function Descriptions:

️· DB9 – DB0: Data input bits (Most Significant Bit to Least Significant Bit).
️· SLEEP: Power-down input.
️· REFLO: Reference ground (can be tied to AVDD to disable the internal reference).
️· REFIO: Reference output (or input if internal reference disabled). Requires a 0.1 µF capacitor to ACOM.
️· FS ADJ: Full-Scale Current Output Adjust.
️· COMP1 & COMP2: Comparators (part of the internal circuitry).
️· ACOM: Analog Common.
️· IOUTB: Complementary DAC Current Output.
️· IOUTA: DAC Current Output.
️· AVDD: Analog Supply Voltage (+2.7 V to +5.5 V).
️· DCOM: Digital Common.
️· DVDD: Digital Supply Voltage (+2.7 V to +5.5 V).
️· CLOCK: Clock Input (data latched on the positive edge).

4. Thermal Characteristics:

️· Theta JA (θJA): Thermal resistance junction to ambient (°C/W). Indicates how well heat is dissipated into the surrounding air. Different values are provided for the 300 mil SOIC and 170 mil TSSOP packages.
️· Theta JC (θJC): Thermal resistance junction to case (°C/W). Indicates how well heat is dissipated into the device case.

5. ESD Sensitivity:

️· The device is sensitive to Electrostatic Discharge (ESD) and requires proper handling precautions.

6. Test Setup (Figure 2):

️· A basic AC characterization test setup is described and visually represented. It outlines connections to equipment like spectrum analyzers and specifies 50 Ohm input impedance.
