LMV824IPWR Equivalent & Substitute Parts
Part Overview
The LMV824IPWR is a general-purpose operational amplifier manufactured by Texas Instruments, featuring four independent circuits in a 14-TSSOP surface-mount package. This device is classified as obsolete, indicating discontinued production and limited availability. The LMV824IPWR delivers rail-to-rail output capability with a gain-bandwidth product of 5.5 MHz, making it suitable for low-power analog signal processing applications across industrial and consumer electronics.
Due to its obsolete status, identifying functionally equivalent active alternatives is essential for design continuity, new production runs, and long-term supply chain reliability. Active substitute parts maintain electrical compatibility while offering improved availability and extended product lifecycles.

- Circuit count: Four independent amplifier circuits
- Output configuration: Rail-to-rail output capability
- Supply voltage range: Minimum 2.5 V, maximum 5.5 V
- Operating temperature range: -40°C to 125°C (or extended range)
- Mounting type: Surface mount
Secondary Electrical Parameters:
- Slew rate: 1.9 V/µs or higher
- Gain-bandwidth product: 5.5 MHz or higher

Engineering Selection Recommendations
Tier 1: Direct Replacement (Recommended)
LMV824MT/NOPB and LMV824MTX/NOPB are the primary recommended substitutes. Both are active Texas Instruments products sharing the LMV824 base part number with identical electrical specifications to the obsolete LMV824IPWR. The primary difference is operating temperature range (-40°C to 85°C versus -40°C to 125°C). These parts are suitable for applications not requiring extended high-temperature operation above 85°C. LMV824MTX/NOPB offers superior inventory availability (35,400 units) in Cut Tape and Digi-Reel packaging.
Tier 2: Cross-Manufacturer Equivalents (Automotive-Qualified)
LMV824AIPT (STMicroelectronics) and LMV824IPT (STMicroelectronics) maintain the full -40°C to 125°C operating range and carry AEC-Q100 automotive qualification. These parts are suitable for automotive and industrial applications requiring extended temperature performance. Input bias current is slightly elevated (60 nA versus 40 nA), and supply current per channel is reduced (300 µA versus 1 mA total). LMV824AIPT is tape-and-reel packaged; LMV824IPT is cut-tape packaged.
Tier 3: onsemi Alternatives
LMV824DTBR2G (onsemi) provides active product status with improved slew rate (2 V/µs) and gain-bandwidth product (5.6 MHz). However, input bias current is elevated (119 nA), and operating temperature is limited to -40°C to 85°C. This part is suitable for non-temperature-critical applications.
Tier 4: Performance-Enhanced Alternatives
AD8604ARUZ-REEL (Analog Devices) exceeds LMV824IPWR specifications in slew rate (6 V/µs), gain-bandwidth product (8.4 MHz), and input offset voltage (80 µV). This CMOS device is suitable for applications requiring superior dynamic performance and precision. Supply current is reduced (750 µA total), and operating temperature extends to -40°C to 125°C.
Not Recommended for Direct Substitution:
AD8619WARUZ-R7, AD8619WARUZ-RL, MC33204DTBR2G, and MCP619-I/ST do not meet the electrical criteria for direct substitution. These devices exhibit significantly different gain-bandwidth products, slew rates, or supply voltage ranges that would require circuit redesign.
Frequently Asked Questions (FAQ)
Q: Can LMV824MT/NOPB replace LMV824IPWR in all applications?
A: LMV824MT/NOPB is electrically compatible with LMV824IPWR for applications operating within -40°C to 85°C. Applications requiring operation above 85°C require alternative selection. Both devices share identical package, circuit count, and core electrical specifications (slew rate, gain-bandwidth product, input bias current, output current).
Q: What is the difference between LMV824MT/NOPB and LMV824MTX/NOPB?
A: Both parts are electrically identical. The difference is packaging: LMV824MT/NOPB is supplied in Tube packaging, while LMV824MTX/NOPB is supplied in Cut Tape and Digi-Reel format. LMV824MTX/NOPB offers significantly higher inventory availability (35,400 units versus 5,150 units).
Q: Why is input bias current higher in LMV824AIPT compared to LMV824IPWR?
A: LMV824AIPT is manufactured by STMicroelectronics and exhibits slightly elevated input bias current (60 nA versus 40 nA). This difference is within acceptable tolerance for most general-purpose amplifier applications. The automotive-qualified variant maintains full -40°C to 125°C temperature range.
Q: Is AD8604ARUZ-REEL a suitable substitute?
A: AD8604ARUZ-REEL is functionally compatible but represents a performance upgrade rather than a direct replacement. It offers superior slew rate (6 V/µs versus 1.9 V/µs) and gain-bandwidth product (8.4 MHz versus 5.5 MHz). This device is suitable for applications requiring enhanced dynamic performance. Pin-level compatibility must be verified for the specific application circuit.
Q: What does "obsolete" status mean for LMV824IPWR?
A: Obsolete status indicates that Texas Instruments has discontinued production and removed the part from active inventory. New designs should not specify LMV824IPWR. Existing designs using this part should transition to active alternatives such as LMV824MT/NOPB or LMV824MTX/NOPB to ensure long-term supply availability.
Q: Can I use MC33204DTBR2G as a substitute?
A: MC33204DTBR2G is not recommended for direct substitution. While it shares the 14-TSSOP package and four-circuit configuration, it exhibits significantly lower gain-bandwidth product (2.2 MHz versus 5.5 MHz) and higher input offset voltage (10 mV versus 1 mV). Circuit redesign would be required to accommodate these electrical differences.
Q: What is the significance of RoHS3 compliance?
A: All listed substitute parts carry RoHS3 compliance certification, confirming restriction of hazardous substances in accordance with EU Directive 2011/65/EU. This certification is mandatory for products sold in European markets and is standard for modern electronic components.
Q: Are there supply voltage compatibility concerns?
A: LMV824IPWR operates across 2.5 V to 5.5 V supply range. Most substitute parts maintain this range. AD8619WARUZ-R7 and AD8619WARUZ-RL operate across 1.8 V to 5 V, which is narrower at the upper limit. MC33204DTBR2G operates across 1.8 V to 12 V, which is wider. Verify supply voltage requirements for your specific application circuit.
Q: What is the difference between Tape & Reel and Cut Tape packaging?
A: Tape & Reel (TR) packaging is supplied on continuous carrier tape suitable for automated pick-and-place assembly equipment. Cut Tape (CT) packaging is supplied as individual segments cut from the carrier tape. Both formats are surface-mount compatible. Selection depends on production volume and assembly equipment capability.
