1. Device Identification:

️· Device Names: AD8033 / AD8034
️· Type: Op Amps (Operational Amplifiers)

2. Absolute Maximum Ratings (Important - Don't Exceed These!)

These are the *absolute* limits. Exceeding them can permanently damage the device.

Parameter	Rating
Supply Voltage (V<sub>S</sub>)	26.4 V
Power Dissipation (P<sub>D</sub>)	See Figure 5 (Dependent on package and ambient temperature)
Common-Mode Input Voltage	26.4 V
Differential Input Voltage	1.4 V
Storage Temperature Range	-65°C to +125°C
Operating Temperature Range	-40°C to +85°C

| Lead Temperature (Soldering) | 300°C (for 10 seconds)

3. Power Dissipation and Junction Temperature

️· Importance: The key is to keep the *junction temperature (T_J)* within safe limits. Exceeding ~175°C can cause permanent damage.
️· Formula: _T_J_ = _T_A_ + (_P_D_ × _θ_JA_)
- _T_J_: Junction Temperature
- _T_A_: Ambient Temperature
- _P_D_: Power Dissipation (total power in the package)
- _θ_JA_: Thermal Resistance from Junction to Ambient (package-dependent)
️· Figure 5: This figure shows how much power the chip can dissipate based on the ambient temperature. This will vary with package type and PCB design.
️· Thermal Resistance: Better PCB design and heat sinks reduce _θ_JA_.
️· Important Note: The text emphasizes minimizing parasitic capacitances at the input leads due to the high speed of the op amps.

4. Output Short Circuit Considerations

️· Danger: Shorting the output or drawing excessive current can lead to catastrophic failure.
️· Recommendation: Avoid output short circuits.

5. Packages and Thermal Resistance (θ_JA) - Approximate Values

Package	θ<sub>JA</sub> (Thermal Resistance)
SOIC-8	125°C/W
SC70-5	210°C/W
SOT-23-8	160°C/W

6. Key Operating Conditions (Vary Depending on Which Table is Referenced)

There are two different sets of operating conditions, which will vary depending on the supplies

Parameter	Table 1	Table 2
Supply Voltage (V<sub>S</sub>)	26.4 V	26.4 V
Common-Mode Input Voltage	26.4 V	26.4 V
Differential Input Voltage	1.4 V	1.4 V
Input Common-Mode Voltage Range	±5 V	±5 V
Input Common-Mode Voltage Range	−12.0 to +9.0	−12.0 to +9.0

Summary of Important Considerations

️· Thermal Management: Critical for reliable operation. Monitor junction temperatures, consider PCB layout and heat sinking.
️· Output Short Circuits: Avoid them.
️· Input Capacitance: Minimize input lead capacitance due to the op amps high-speed operation.
️· Refer to Table 5: Use Table 5 for a better understanding of maximum power dissipation.
️· Reference Table 1 and 2: Review the operating conditions for both tables.
