Engineering Selection Recommendations
Direct Replacement (Identical Electrical Performance):
LMV116MFX/NOPB is the active production equivalent of the obsolete LMV116MFX. This part maintains identical electrical specifications including slew rate (35 V/µs), bandwidth (45 MHz), supply current (600 µA), and output current (20 mA). The primary advantage is active product status and ROHS3 compliance, enabling continued procurement and design support. This part is recommended for direct substitution in existing designs without circuit modification.
Enhanced Performance Substitutes (Higher Bandwidth and Slew Rate):
AD8051ARTZ-REEL and AD8051ARTZ-REEL7 provide enhanced performance with 170 V/µs slew rate and 110 MHz bandwidth, representing 4.9× and 2.4× improvements respectively. Supply current increases to 4.8 mA and output current to 45 mA. Operating temperature extends to 125°C. These parts are suitable for applications requiring higher frequency response and faster transient performance. Minimum supply voltage increases from 2.5 V to 3 V.
Video Amplifier Substitutes (Maximum Performance):
LT6205 series (CS5, HS5, IS5 variants) deliver 600 V/µs slew rate and 60 mA output current, optimized for video and high-speed signal conditioning applications. Supply current is 4 mA. These parts use TSOT-23-5 thin package variant. Voltage supply range extends to 12.6 V maximum. Temperature grades vary by suffix (C, H, I designate commercial, high-temperature, and industrial grades).
Maximum Output Current Substitute:
MAX4012EUK+T provides 600 V/µs slew rate, 200 MHz bandwidth, and 120 mA output current for applications requiring high current drive capability. Supply current is 5.5 mA. Operating temperature range matches the original at -40°C to 85°C. Maximum supply voltage is limited to 11 V.
Compliance and Availability Considerations:
All substitute parts listed are ROHS3 compliant and carry active product status, ensuring long-term availability and regulatory compliance for new designs. The LMV116MFX/NOPB is the preferred choice for designs requiring no circuit modification. Performance-enhanced alternatives should be selected only when application requirements justify increased power consumption and component cost.
Frequently Asked Questions (FAQ)
Q: Can LMV116MFX/NOPB be used as a direct replacement for LMV116MFX?
A: Yes. LMV116MFX/NOPB is the active production equivalent with identical electrical specifications. The primary differences are product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). No circuit modifications are required.
Q: What is the key difference between LMV116MFX and AD8051ARTZ-REEL?
A: AD8051ARTZ-REEL provides enhanced performance with 170 V/µs slew rate (vs. 35 V/µs) and 110 MHz bandwidth (vs. 45 MHz). Supply current increases from 600 µA to 4.8 mA, and output current increases from 20 mA to 45 mA. Minimum supply voltage increases from 2.5 V to 3 V. These differences require circuit evaluation before substitution.
Q: Are the LT6205 variants (CS5, HS5, IS5) pin-compatible with LMV116MFX?
A: Yes, all parts use SOT-23-5 or TSOT-23-5 surface mount packages with identical pinout. However, LT6205 variants use TSOT-23-5 thin package, which may require PCB layout verification for mechanical clearance. Electrical performance is significantly enhanced with 600 V/µs slew rate and 60 mA output current.
Q: What does the suffix designation mean in LT6205 part numbers (CS5#TRMPBF, HS5#TRMPBF, IS5#TRPBF)?
A: The letter suffix indicates temperature grade: C = commercial grade, H = high-temperature grade, I = industrial grade. The #TR designation indicates tape and reel packaging. The final suffix (MPBF or PBF) indicates lead-free RoHS compliance. All variants have identical electrical specifications.
Q: Can MAX4012EUK+T replace LMV116MFX in all applications?
A: MAX4012EUK+T is electrically compatible but provides enhanced performance (600 V/µs slew rate, 200 MHz bandwidth, 120 mA output current). The maximum supply voltage is limited to 11 V (vs. 12 V for LMV116MFX). Applications operating above 11 V require alternative selection. Increased supply current (5.5 mA vs. 600 µA) must be evaluated for power budget constraints.
Q: What is the minimum supply voltage requirement for each substitute?
A: LMV116MFX and LMV116MFX/NOPB: 2.5 V minimum. AD8051ARTZ-REEL and AD8051ARTZ-REEL7: 3 V minimum. LT6205 series: 2.7 V minimum. MAX4012EUK+T: 3.15 V minimum. Applications with supply voltages below 3 V must use LMV116MFX/NOPB or LT6205 series.
Q: Are all substitute parts ROHS3 compliant?
A: Yes. All substitute parts listed carry ROHS3 compliance certification. The original LMV116MFX is RoHS non-compliant. For designs requiring RoHS compliance, LMV116MFX/NOPB or any performance-enhanced substitute is required.
Q: What is the inventory status for each part?
A: LMV116MFX: 7,590 pcs (obsolete). LMV116MFX/NOPB: 39,806 pcs (active). AD8051ARTZ-REEL: 13,320 pcs (active). AD8051ARTZ-REEL7: 12,611 pcs (active). LT6205CS5#TRMPBF: 1,800 pcs (active). LT6205HS5#TRMPBF: 1,690 pcs (active). LT6205IS5#TRPBF: 2,318 pcs (active). MAX4012EUK+T: 5,426 pcs (active). LMV116MFX/NOPB offers the highest inventory availability.
