TLV2784IPWR Equivalent & Substitute Parts
Part Overview
The TLV2784IPWR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-TSSOP surface-mount package. This rail-to-rail CMOS amplifier operates across a supply voltage range of 1.8V to 3.6V and is designed for low-power applications requiring moderate bandwidth performance. The device is currently in active production status with full RoHS3 compliance and unlimited moisture sensitivity rating.
Substitute parts are identified when equivalent functional performance can be achieved within the specified electrical and mechanical constraints of the application, particularly when the original part becomes unavailable or when alternative packaging formats are required for manufacturing optimization.

Engineering Selection Recommendations
All listed substitute parts maintain active production status and full RoHS3 compliance with MSL Level 1 rating, meeting the regulatory and environmental requirements of the TLV2784IPWR.
For 14-TSSOP Package Continuity: AD8508ARUZ, AD8604ARUZ-REEL, AD8609ARUZ, AD8609ARUZ-REEL, AD8619ARUZ, and AD8619ARUZ-REEL maintain identical 14-TSSOP packaging. Selection among these depends on application-specific requirements for slew rate, gain-bandwidth product, input offset voltage, and supply current characteristics.
For Space-Constrained Applications: AD8508ACBZ-REEL7 provides four-circuit amplification in a compact 14-WLCSP (1.46x2.96) package, suitable for miniaturized designs where board area is critical.
For Alternative Packaging: AD8609ARZ and AD8609ARZ-REEL7 offer identical electrical specifications to their 14-TSSOP counterparts but in 14-SOIC format (0.154", 3.90mm Width), accommodating designs with existing SOIC footprints.
All substitute parts are manufactured by Analog Devices Inc., a qualified supplier with established quality and reliability standards equivalent to Texas Instruments.
Frequently Asked Questions (FAQ)
Q1: Can AD8508ARUZ directly replace TLV2784IPWR in the same PCB footprint?
A: Yes, AD8508ARUZ maintains the identical 14-TSSOP package dimensions (0.173", 4.40mm Width) and pinout compatibility. However, electrical characteristics differ significantly: AD8508ARUZ has lower slew rate (0.013V/µs vs. 5V/µs) and lower gain-bandwidth product (95 kHz vs. 8 MHz). Substitution is valid only when application bandwidth and slew rate requirements are compatible with these lower specifications.
Q2: What is the primary difference between AD8609ARUZ and AD8619ARUZ?
A: Both devices share identical 14-TSSOP packaging, operating temperature range, and supply voltage specifications. The primary difference is input offset voltage: AD8609ARUZ specifies 12 µV while AD8619ARUZ specifies 400 µV. AD8609ARUZ is suitable for precision applications requiring lower offset voltage; AD8619ARUZ is appropriate for general-purpose applications with relaxed offset requirements.
Q3: Why does AD8604ARUZ-REEL have a higher minimum supply voltage (2.7V) compared to TLV2784IPWR (1.8V)?
A: AD8604ARUZ-REEL operates within a 2.7V to 5.5V supply range, which does not overlap with the TLV2784IPWR minimum specification of 1.8V. This part is not suitable for applications requiring operation below 2.7V supply voltage.
Q4: Is AD8508ACBZ-REEL7 in 14-WLCSP package compatible with standard 14-TSSOP PCB layouts?
A: No. The 14-WLCSP package (1.46x2.96mm) uses ball-grid-array (BGA) interconnection technology and requires a different PCB footprint than 14-TSSOP. AD8508ACBZ-REEL7 is suitable only for designs with dedicated WLCSP footprints and assembly capabilities for BGA soldering.
Q5: Do all substitute parts meet the same compliance standards as TLV2784IPWR?
A: Yes. All listed substitute parts are RoHS3 compliant, REACH unaffected, and carry MSL Level 1 (Unlimited) moisture sensitivity rating, matching the compliance profile of TLV2784IPWR.
Q6: Which substitute part offers the lowest supply current consumption?
A: AD8508ACBZ-REEL7 and AD8508ARUZ both specify 15 µA total supply current (x4 channels), representing the lowest consumption among all listed substitutes. This is significantly lower than TLV2784IPWR at 650 µA, making these parts suitable for ultra-low-power applications.
Q7: Can AD8609ARZ (14-SOIC) be used as a substitute if my PCB currently has 14-TSSOP footprints?
A: No. The 14-SOIC package (0.154", 3.90mm Width) has different pin spacing and body dimensions than 14-TSSOP (0.173", 4.40mm Width). PCB footprint redesign is required. However, electrical specifications are identical to AD8609ARUZ, making it suitable for new designs with SOIC footprints.
