Key Parameters

Substitute Part Grouping Explanation

Substitution of the TLV2244IPWR with the AD8040WARUZ-REEL7 is based on the following alignment of critical parameters:

Mechanical Compatibility: Both components utilize the 14-TSSOP surface-mount package with identical physical dimensions (0.173", 4.40mm width), enabling direct PCB footprint compatibility without layout modifications.

Functional Equivalence: Both devices are four-circuit general-purpose operational amplifiers with rail-to-rail output capability. Both operate within the -40°C to 125°C temperature range and support supply voltages from minimum 2.5V to maximum 12V.

Regulatory Compliance: Both parts maintain RoHS3 compliance, MSL Level 1 (unlimited moisture sensitivity), and identical ECCN and HTSUS classifications, ensuring equivalent regulatory and environmental qualification status.

Substitution Criteria: The AD8040WARUZ-REEL7 qualifies as a substitute based on matching package type, circuit count, output configuration, temperature range, and supply voltage specifications. Performance characteristics differ significantly; the substitute exhibits higher slew rate, bandwidth, input bias current, and output current capabilities.

Parameter Comparison

Engineering Selection Recommendations

Primary Selection Criteria:

The TLV2244IPWR is the preferred component when low-power operation and minimal input bias current are design requirements. The device's 100 pA input bias current and 1 µA supply current per channel support ultra-low-power applications with stringent power consumption constraints.

The AD8040WARUZ-REEL7 substitute is appropriate when higher-speed signal processing, increased output current capability, or higher bandwidth performance is required. The substitute's 63 V/µs slew rate and 125 MHz bandwidth support dynamic signal conditioning applications beyond the primary device's specifications.

Compliance and Regulatory Alignment:

Both components maintain identical RoHS3 compliance status, MSL Level 1 rating, and regulatory classification (ECCN EAR99, HTSUS 8542.33.0001). Both devices support the full -40°C to 125°C industrial temperature range and operate within overlapping supply voltage ranges (2.5V to 12V for TLV2244IPWR; 2.7V to 12V for AD8040WARUZ-REEL7).

Mechanical Compatibility:

Direct substitution is supported at the PCB level. Both components utilize identical 14-TSSOP surface-mount packaging with matching footprint dimensions, eliminating the requirement for layout redesign or assembly process modification.

Inventory and Availability:

Selection between these components may be driven by inventory availability. The TLV2244IPWR maintains 2400 units in stock, while the AD8040WARUZ-REEL7 maintains 4208 units in stock.

Frequently Asked Questions (FAQ)

Q: Can the AD8040WARUZ-REEL7 be used as a direct replacement for the TLV2244IPWR on existing PCBs?

A: Yes. Both components share identical 14-TSSOP package geometry and pinout configuration. No PCB layout modifications are required for mechanical substitution. However, the higher performance characteristics of the AD8040WARUZ-REEL7 (increased slew rate, bandwidth, and supply current) must be evaluated against circuit design specifications to ensure compatibility with power supply capacity and signal conditioning requirements.

Q: What are the key performance differences between these two amplifiers?

A: The AD8040WARUZ-REEL7 exhibits significantly higher dynamic performance: 63 V/µs slew rate versus 0.002 V/µs, 125 MHz bandwidth versus 5.5 kHz, and 170 mA output current per channel versus 200 µA. The TLV2244IPWR maintains lower input bias current (100 pA versus 700 nA) and lower supply current consumption (1 µA versus 1.4 mA per channel). Selection depends on whether the application prioritizes low-power operation or high-speed signal processing.

Q: Are both components RoHS compliant?

A: Yes. Both the TLV2244IPWR and AD8040WARUZ-REEL7 maintain full RoHS3 compliance with MSL Level 1 (unlimited) moisture sensitivity rating. Both components are REACH unaffected and share identical ECCN and HTSUS classifications.

Q: What is the minimum supply voltage difference between these components?

A: The TLV2244IPWR operates at a minimum supply voltage of 2.5V, while the AD8040WARUZ-REEL7 requires a minimum of 2.7V. Applications operating at 2.5V to 2.6V supply voltage must use the TLV2244IPWR. Both components support maximum supply voltage of 12V.

Q: Do both amplifiers support the same temperature operating range?

A: Yes. Both the TLV2244IPWR and AD8040WARUZ-REEL7 operate across the -40°C to 125°C temperature range, supporting industrial and extended-temperature applications without thermal derating considerations.

Q: Which component should be selected for battery-powered applications?

A: The TLV2244IPWR is the appropriate selection for battery-powered designs. Its 1 µA supply current per channel (4 µA total for four circuits) significantly reduces power consumption compared to the AD8040WARUZ-REEL7's 1.4 mA per channel specification. This difference becomes critical in applications requiring extended battery life or minimal power draw.

Q: Can these components be used interchangeably in high-frequency signal conditioning circuits?

A: No. The TLV2244IPWR's 5.5 kHz gain-bandwidth product and 0.002 V/µs slew rate limit its application to low-frequency signal conditioning. The AD8040WARUZ-REEL7's 125 MHz bandwidth and 63 V/µs slew rate support high-frequency applications. Component selection must align with circuit bandwidth requirements.
