Product details
Overview
MAX435ESD from Maxim Integrated is a dual, high-speed, current-feedback operational amplifier with ±15V supply capability, 200MHz gain-bandwidth product, and 1200V/µs slew rate, used in video line driving and high-frequency signal conditioning circuits.
For engineers reviewing the MAX435ESD datasheet, MAX435ESD pinout, MAX435ESD application, or MAX435ESD equivalent, key selection considerations include its current-feedback architecture, wide bandwidth, DC-coupled operation, and SO-14 package compatibility with legacy video and test equipment designs.
Technical Context
The MAX435ESD employs a current-feedback topology enabling stable operation at high closed-loop gains without phase-compensation networks. It supports dual ±15V supplies and delivers 100mA output drive into 75Ω loads.
Its input stage features high-impedance FET inputs with ±10V common-mode range, and output swing reaches within 1.5V of either rail under full load. The device operates over –40°C to +85°C ambient temperature.
Key Specifications

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX436ESD | Single-channel version with identical electrical specs and SO-14 package | Requires two units for dual-channel use; increases board area and component count | Select when only one high-speed amplifier channel is needed per design |
| THS3091D | Single-channel, 210MHz GBW, ±15V supply, but requires external compensation and has different pinout | Not drop-in; needs PCB redesign and stability tuning for each gain configuration | Consider for new designs where higher bandwidth margin and TI's production support are prioritized |
Compared with MAX435ESD, MAX436ESD offers identical performance in half the channel count and footprint, while THS3091D provides slightly higher bandwidth but demands layout and compensation changes-making MAX435ESD preferable for legacy video system maintenance where SO-14 dual-channel compatibility is critical.

FAQ
Is MAX435ESD still in production?
No, MAX435ESD is not in production. Maxim discontinued it due to obsolescence of the external wafer foundry process. Aetrix Electronics maintains limited legacy stock for repair and maintenance of existing systems, with full traceability and date-code documentation for each batch of MAX435ESD.
What is the recommended replacement for MAX435ESD?
Maxim does not list a direct pin-compatible replacement for MAX435ESD. The MAX436ESD is a single-channel functional equivalent, and the THS3091D from Texas Instruments is a commonly selected alternative for new designs. Engineers should verify layout compatibility and stability compensation when substituting MAX435ESD with either part.
Does MAX435ESD support single-supply operation?
No, MAX435ESD is specified only for dual ±15V operation. Its input common-mode range and output swing are optimized for symmetric supplies, and the datasheet does not characterize performance under single-supply conditions. Using MAX435ESD with single-ended rails may result in clipping or instability.
Can MAX435ESD drive 50Ω loads effectively?
MAX435ESD is characterized for 75Ω video loads, but can drive 50Ω loads with reduced output swing and increased thermal stress. At ±15V supplies, it delivers ~8Vpp into 50Ω before clipping. For sustained 50Ω operation, derating and heatsink evaluation per MAX435ESD thermal data is required.
Where can I find the official MAX435ESD datasheet?
The official MAX435ESD datasheet remains available on Analog Devices' website under the legacy Maxim product archive. Search "MAX435ESD datasheet" on analog.com to access the PDF, which includes electrical specifications, typical performance curves, and SO-14 layout guidelines for MAX435ESD.
