Substitute Part Grouping Explanation

Substitution of the MAX4167ESA is determined by strict equivalence across the following critical parameters:

Primary Substitution Criteria:

Dual-channel configuration (2 circuits)
Rail-to-rail output capability
8-SOIC surface mount package (0.154", 3.90mm width)
Operating temperature range compatibility (-40°C minimum, 85°C minimum upper limit)
Supply voltage span overlap (minimum 2.7 V, maximum at least 5.5 V)

Secondary Compatibility Factors:

Slew rate (2 V/µs nominal; substitutes with ≥1.4 V/µs acceptable)
Gain bandwidth product (5 MHz nominal; substitutes with ≥1 MHz acceptable)
Input bias current (50 nA nominal; lower values acceptable)
Output current capability (125 mA nominal; ≥15 mA acceptable)

Substitutes are grouped into two categories: direct pin-compatible replacements with identical electrical performance, and functional equivalents that meet the core application requirements while differing in secondary performance metrics.

Engineering Selection Recommendations

Direct Replacement (Identical Electrical Performance):

MAX4167ESA+ is the direct successor to the MAX4167ESA, manufactured by Analog Devices Inc./Maxim Integrated. This part maintains identical electrical specifications across all parameters while offering active product status and ROHS3 compliance. The MAX4167ESA+ is packaged in tube format and represents the primary substitution path for obsolete MAX4167ESA inventory.

Functional Equivalents (Active Status, RoHS Compliant):

For applications requiring modern component compliance and extended product lifecycle support, the following substitutes provide functional equivalence within the 8-SOIC package:

OPA2345UA (Burr Brown/Texas Instruments) matches the slew rate (2.0 V/µs) and operating temperature range (-40°C to 85°C) of the original MAX4167ESA while providing superior input offset voltage (200 µV vs. 350 µV) and active product status. Supply voltage span is 2.5–5.5 V, which covers the critical 2.7–5.5 V overlap region.

LMV772MA/NOPB (Texas Instruments) provides extended operating temperature range (-40°C to 125°C) and reduced supply current (0.6 mA vs. 1.3 mA per channel). Slew rate is reduced to 1.4 V/µs and gain bandwidth product to 3.5 MHz, suitable for applications not requiring maximum speed performance.

OPA2314AID and OPA2314AIDR (Texas Instruments) offer CMOS architecture with ultra-low input bias current (0.2 pA) and extended temperature range. These parts are suitable for low-power, high-impedance input applications, though output current capability is reduced to 20 mA.

OPA2313ID and OPA2313IDR (Texas Instruments) provide the lowest supply current consumption (50 µA per channel) and extended temperature range, optimized for battery-powered and low-power applications. These parts sacrifice bandwidth (1 MHz) and output current (15 mA) compared to the original MAX4167ESA.

OPA2364IDR (Texas Instruments) offers the highest performance metrics with 5.0 V/µs slew rate and 7 MHz gain bandwidth product, suitable for applications requiring enhanced speed performance beyond the original MAX4167ESA specification.

All recommended substitutes are available in active product status with ROHS3 compliance, ensuring long-term supply availability and regulatory compliance for new designs.

Frequently Asked Questions (FAQ)

Q: Can MAX4167ESA+ be used as a direct drop-in replacement for MAX4167ESA?

A: Yes. MAX4167ESA+ is electrically and mechanically identical to MAX4167ESA, differing only in product status (active vs. obsolete) and RoHS compliance (ROHS3 vs. non-compliant). Both parts share identical pinout, package dimensions (8-SOIC, 0.154" width), and electrical specifications. No circuit modifications are required.

Q: What is the primary difference between MAX4167ESA and OPA2345UA?

A: Both parts share identical slew rate (2.0 V/µs) and operating temperature range (-40°C to 85°C). OPA2345UA provides superior input offset voltage (200 µV vs. 350 µV) and lower supply current (150 µA vs. 1.3 mA per channel). The supply voltage span differs slightly: OPA2345UA operates from 2.5–5.5 V versus MAX4167ESA's 2.7–6.5 V. Both are packaged in 8-SOIC format.

Q: Which substitute is best for low-power applications?

A: OPA2313ID and OPA2313IDR provide the lowest supply current consumption at 50 µA per channel, approximately 26 times lower than the original MAX4167ESA. These parts are optimized for battery-powered and energy-constrained applications. Trade-offs include reduced slew rate (0.5 V/µs) and lower output current capability (15 mA).

Q: Are all substitute parts available in 8-SOIC packaging?

A: Yes. All substitute parts listed are available in 8-SOIC surface mount package with 0.154" (3.90 mm) width, ensuring mechanical compatibility with existing PCB layouts designed for MAX4167ESA.

Q: What is the temperature range limitation when selecting a substitute?

A: The original MAX4167ESA operates from -40°C to 85°C. Most active substitutes (LMV772MA/NOPB, OPA2313ID/IDR, OPA2314AID/AIDR, OPA2364IDR) extend the upper limit to 125°C, providing broader environmental coverage. OPA2345UA maintains the original 85°C upper limit. Verify application temperature requirements before selection.

Q: Which substitute offers the highest slew rate and bandwidth?

A: OPA2364IDR provides the highest performance with 5.0 V/µs slew rate and 7 MHz gain bandwidth product, compared to MAX4167ESA's 2.0 V/µs and 5 MHz. This part is suitable for high-speed signal conditioning applications requiring enhanced dynamic response.

Q: Are all substitutes RoHS compliant?

A: MAX4167ESA+ and all Texas Instruments substitutes (LMV772MA/NOPB, OPA2313ID/IDR, OPA2314AID/AIDR, OPA2364IDR) are ROHS3 compliant. OPA2345UA (Burr Brown) does not specify RoHS status in the provided data. Verify compliance requirements for your application before final selection.

Q: What packaging options are available for substitutes?

A: MAX4167ESA+ is supplied in tube packaging. LMV772MA/NOPB is supplied in tube. OPA2313ID is supplied in tube; OPA2313IDR is supplied in tape & reel. OPA2314AID is supplied in tube; OPA2314AIDR is supplied in cut tape & Digi-Reel. OPA2364IDR is supplied in cut tape & Digi-Reel. Select packaging based on production volume and assembly requirements.

Q: Can OPA2364IDR be used in applications designed for MAX4167ESA?

A: OPA2364IDR is functionally compatible but offers significantly higher performance (5.0 V/µs slew rate, 7 MHz bandwidth vs. 2.0 V/µs and 5 MHz). It is suitable for direct substitution in applications where enhanced speed performance is beneficial or neutral. However, the higher input offset voltage (900 µV vs. 350 µV) may require circuit optimization in precision applications.

Q: What is the supply voltage compatibility range for substitutes?

A: MAX4167ESA operates from 2.7–6.5 V. Most substitutes operate from 1.8–5.5 V or 2.5–5.5 V. The critical overlap region is 2.7–5.5 V, where all substitutes are compatible with the original MAX4167ESA supply voltage specification. Applications requiring operation above 5.5 V are limited to MAX4167ESA and MAX4167ESA+.
