MAX4483AUD+ Equivalent & Substitute Parts Reference

Part Overview

The MAX4483AUD+ is a general purpose operational amplifier manufactured by Analog Devices Inc./Maxim Integrated, configured as a 4-circuit rail-to-rail amplifier in a 14-TSSOP surface mount package. This device is classified as obsolete product status, making equivalent and substitute parts necessary for ongoing design support and procurement continuity.

The MAX4483AUD+ operates across a 2.5V to 5.5V supply range with a gain bandwidth product of 140 kHz and slew rate of 0.08V/µs. Its low input bias current of 0.1 pA and 1 mV input offset voltage support precision analog signal conditioning applications. The device is ROHS3 compliant with unlimited moisture sensitivity level (MSL 1).

Due to obsolete status, substitute parts with equivalent or enhanced electrical and mechanical characteristics are required for new designs and production continuity.

Number of circuits: 4 independent amplifier channels
Output configuration: Rail-to-rail output capability
Supply voltage range: Minimum 2.5V, maximum 5.5V
Operating temperature range: -40°C to 125°C (preferred for industrial applications)

Electrical Performance Parameters:

Slew rate: 0.08V/µs or higher
Gain bandwidth product: 140 kHz or higher
Input bias current: 0.1 pA or lower
Input offset voltage: 1 mV or lower

Engineering Selection Recommendations

For Direct Functional Replacement (Obsolete Part Substitution):

The MCP6424T-E/ST and MCP6424-E/ST from Microchip Technology provide the closest functional match to the MAX4483AUD+. Both devices maintain the 14-TSSOP package, 4-circuit configuration, and extended operating temperature range of -40°C to 125°C. These parts are active products with ROHS3 compliance and unlimited moisture sensitivity level. The MCP6424 series exhibits lower slew rate (0.05V/µs) and reduced gain bandwidth product (90 kHz) compared to the original, but maintains superior input bias current performance (1 pA) and lower supply current consumption (4.4µA per channel).

For Enhanced Performance Applications:

The LMV824AIPT from STMicroelectronics and LMV824MT/NOPB or LMV824MTX/NOPB from Texas Instruments offer significantly improved dynamic performance with slew rates of 1.9V/µs to 2V/µs and gain bandwidth products of 5.5 to 5.6 MHz. The LMV824AIPT maintains the full -40°C to 125°C temperature range and includes AEC-Q100 automotive qualification. These devices are suitable for applications requiring higher bandwidth and faster transient response.

For Low-Power Supply Voltage Applications:

The BD12734FVJ-E2 from Rohm Semiconductor supports minimum supply voltage of 1.8V, extending compatibility to lower-voltage systems while maintaining 4-circuit rail-to-rail configuration in 14-TSSOP packaging.

For CMOS Technology Preference:

The MCP6474T-E/ST and MCP6474-E/ST from Microchip Technology, and LMR344FVJ-E2 from Rohm Semiconductor provide CMOS amplifier implementations with enhanced input bias current performance (1 pA) and higher output current capability (32 to 113 mA per channel). These devices support the full -40°C to 125°C operating range (MCP6474 series) or -40°C to 85°C (LMR344FVJ-E2).

All recommended substitutes are active products with ROHS3 compliance, REACH unaffected status, and EAR99 ECCN classification, matching the regulatory profile of the original MAX4483AUD+.

Frequently Asked Questions (FAQ)

Q: Can the MCP6424T-E/ST directly replace the MAX4483AUD+ in existing designs?

A: The MCP6424T-E/ST is mechanically and electrically compatible as a direct replacement. Both devices use the 14-TSSOP package, contain 4 independent rail-to-rail amplifier circuits, and operate across the 2.5V to 5.5V supply range. The MCP6424T-E/ST maintains the -40°C to 125°C operating temperature range. However, the MCP6424T-E/ST exhibits lower slew rate (0.05V/µs versus 0.08V/µs) and reduced gain bandwidth product (90 kHz versus 140 kHz). Applications sensitive to these performance parameters require circuit re-evaluation.

Q: What is the key difference between general purpose and CMOS substitute options?

A: General purpose substitutes (MCP6424 series, LMV824 series, BD12734FVJ-E2, LMR934FVJ-E2) use bipolar or BiCMOS technology and provide moderate slew rates and bandwidth. CMOS substitutes (MCP6474 series, LMR344FVJ-E2) feature extremely low input bias currents (1 pA) and higher output current capability, making them suitable for precision instrumentation and high-impedance signal sources. CMOS devices typically consume less supply current but may exhibit higher input offset voltage variation with temperature.

Q: Are all substitute parts available in the same packaging options as the MAX4483AUD+?

A: All substitute parts are available in 14-TSSOP surface mount packages. However, packaging designations vary by manufacturer. Rohm Semiconductor parts use 14-TSSOP-BJ designation. Verify specific packaging options (Tube, Tape & Reel, Cut Tape) with your supplier, as availability differs by part number suffix.

Q: Which substitute part offers the best low-power performance?

A: The MCP6424T-E/ST and MCP6424-E/ST provide the lowest supply current consumption at 4.4µA per channel (total 17.6µA for 4 channels), compared to 50µA per channel in the original MAX4483AUD+. This represents a 72% reduction in quiescent current, making these parts ideal for battery-powered and energy-constrained applications.

Q: Can I use LMV824 series parts in applications requiring -40°C to 125°C operation?

A: The LMV824AIPT from STMicroelectronics supports the full -40°C to 125°C operating range. However, the LMV824MT/NOPB and LMV824MTX/NOPB from Texas Instruments are rated only to 85°C maximum. Verify temperature requirements before selection.

Q: What is the significance of the AEC-Q100 qualification on the LMV824AIPT?

A: AEC-Q100 qualification indicates the LMV824AIPT meets automotive industry reliability and quality standards. This certification is relevant only for automotive applications. For industrial or consumer applications, this qualification provides no functional advantage.

Q: Are there supply chain or inventory considerations for substitute selection?

A: Inventory availability varies significantly. The LMV824MTX/NOPB from Texas Instruments shows the highest inventory level (35,400 pieces), while the LMR934FVJ-E2 from Rohm Semiconductor offers 3,126 pieces. MCP6424 and MCP6474 series from Microchip Technology maintain moderate inventory levels (2,200 to 3,733 pieces). Verify current availability with your component supplier before design commitment.

Q: Do all substitute parts maintain ROHS3 compliance?

A: Yes, all substitute parts listed are ROHS3 compliant with REACH unaffected status and EAR99 ECCN classification, matching the regulatory compliance profile of the original MAX4483AUD+.
