Engineering Selection Recommendations
Primary Substitute (Recommended for Direct Replacement):
LM7332MMX/NOPB is the manufacturer-recommended substitute. This part maintains identical electrical specifications to the LM7332MME/NOPB with 12 V/µs slew rate, 21 MHz gain bandwidth product, and 70 mA output current per channel. The only difference is packaging format (Tape & Reel versus Cut Tape & Digi-Reel®). Both parts are ROHS3 compliant with MSL 1 rating and Active product status, ensuring long-term availability and supply chain stability.
Secondary Substitutes (Performance-Dependent Selection):
The ADA4084-2ARMZ series (available in Tube, Cut Tape, and Tape & Reel formats) provides Active status with reduced slew rate (4.6 V/µs) and lower output current (30 mA per channel). This series is suitable for applications where the LM7332MME/NOPB's higher performance specifications exceed requirements. Supply voltage range is reduced to 3–30 V maximum.
The ADA4096-2ARMZ and ADA4096-2WARMZ series offer ultra-low input bias current (3 nA) and minimal input offset voltage (35 µV), with significantly reduced slew rate (0.4 V/µs) and gain bandwidth product (786 kHz). These parts are appropriate for precision measurement and low-noise applications where the LM7332MME/NOPB's higher bandwidth is not required. Supply voltage range is 3–30 V maximum.
The ISL28218FUZ series from Renesas Electronics Corporation provides intermediate performance characteristics with 1.2 V/µs slew rate and 4 MHz gain bandwidth product. This series supports extended supply voltage range to 40 V maximum and is available in Tape & Reel packaging only.
All substitute parts maintain ROHS3 compliance and MSL 1 rating. Selection should be based on specific application requirements for slew rate, gain bandwidth product, output current, and supply voltage range.
Frequently Asked Questions (FAQ)
Q: Can LM7332MMX/NOPB be used as a direct replacement for LM7332MME/NOPB?
A: Yes. LM7332MMX/NOPB is electrically identical to LM7332MME/NOPB with the same slew rate (12 V/µs), gain bandwidth product (21 MHz), and output current (70 mA per channel). The difference is packaging format: LM7332MMX/NOPB is supplied in Tape & Reel format while LM7332MME/NOPB is supplied in Cut Tape & Digi-Reel® format. Both are ROHS3 compliant with Active product status.
Q: What are the key differences between the ADA4084 and ADA4096 series?
A: The ADA4084 series has higher slew rate (4.6 V/µs versus 0.4 V/µs) and higher gain bandwidth product (15.9 MHz versus 786 kHz). The ADA4096 series has significantly lower input bias current (3 nA versus 140 nA) and lower input offset voltage (35 µV versus 60 µV). The ADA4084 is suitable for general purpose applications requiring moderate bandwidth; the ADA4096 is optimized for precision measurement applications requiring minimal input current and offset.
Q: Are all substitute parts compatible with the same PCB layout as LM7332MME/NOPB?
A: All substitute parts use the same 8-TSSOP/8-MSOP package with 0.118" width and 3.00mm body width. Pin configuration and spacing are identical, allowing direct PCB layout compatibility. However, packaging format differences (Cut Tape, Tube, or Tape & Reel) affect component handling and assembly processes, not PCB layout.
Q: What is the minimum supply voltage for each substitute part?
A: LM7332MME/NOPB and LM7332MMX/NOPB support 2.5 V minimum supply voltage. ADA4084, ADA4096, and ISL28218 series require minimum 3 V supply voltage. Applications operating below 3 V must use the LM7332 series.
Q: Which substitute part has the lowest power consumption?
A: ADA4096-2ARMZ and ADA4096-2WARMZ series have the lowest supply current at 60 µA total (x2 channels). LM7332MME/NOPB draws 2 mA total. ADA4084 series draws 625 µA total. ISL28218FUZ series draws 850 µA total. Selection depends on application power budget requirements.
Q: Can ISL28218FUZ parts be used in applications requiring supply voltages above 32 V?
A: Yes. ISL28218FUZ-T13 and ISL28218FUZ-T7 support maximum supply voltage of 40 V, compared to 32 V maximum for LM7332 and 30 V maximum for ADA4084 and ADA4096 series. ISL28218 is the only substitute option for applications requiring 32–40 V supply range.
Q: Are all substitute parts available in Cut Tape & Digi-Reel® packaging?
A: LM7332MMX/NOPB, ADA4084-2ARMZ-R7, ADA4096-2ARMZ-R7, and ADA4096-2WARMZ-R7 are available in Cut Tape & Digi-Reel® format. ADA4084-2ARMZ and ADA4096-2ARMZ are available in Tube format. ADA4084-2ARMZ-RL, ADA4096-2ARMZ-RL, ADA4096-2WARMZ-RL, ISL28218FUZ-T13, and ISL28218FUZ-T7 are available in Tape & Reel format.
Q: What is the MSL rating for ISL28218FUZ parts?
A: ISL28218FUZ series has MSL 2 rating (1 Year), compared to MSL 1 (Unlimited) for all other substitute parts. This indicates slightly higher moisture sensitivity requiring controlled storage conditions for ISL28218 components.
