Analog Devices Inc./Maxim Integrated MAX4392ESA+

Overview

MAX4392ESA+ from Analog Devices is a dual-channel, rail-to-rail output, unity-gain stable voltage-feedback op amp with disable functionality, 85MHz -3dB bandwidth, 500V/μs slew rate, and ±2.25V to ±5.5V dual-supply operation. It delivers 0.015% differential gain and 0.015° differential phase error for precision video line driving in surveillance systems and set-top boxes.

For engineers reviewing the MAX4392ESA+ datasheet, MAX4392ESA+ pinout, MAX4392ESA+ application, or MAX4392ESA+ equivalent, this page provides verified electrical specifications, SO-8 package terminal mapping, video-system design context, and validated alternative options for analog signal conditioning and high-speed buffer applications.

Technical Context

The MAX4392ESA+ employs BiCMOS process technology and current-feedback techniques to achieve high-speed performance while maintaining voltage-feedback stability. Its input stage supports common-mode voltage down to VEE (–5V) and up to VCC – 2.25V (2.75V on ±5V supplies), enabling direct interface with video DAC outputs and CCD sensors.

It features internally compensated unity-gain stability, rail-to-rail output swing (within 200mV of rails into 75Ω), and low-output impedance (0.6Ω at 5MHz). The device lacks disable capability-unlike MAX4393/MAX4394/MAX4396-making it suitable for always-on video distribution paths where channel isolation (–97dB DC) and minimal crosstalk are critical.

Key Specifications

Pinout & Package

MAX4392ESA+ is housed in an 8-pin SO (Small Outline) package with standard JEDEC MS-012AC footprint and 1.27mm pitch. Thermal resistance θJA is 120°C/W (single-layer board), supporting continuous operation at ambient temperatures up to +70°C with appropriate PCB copper area.

Manufacturer

Analog Devices is a global leader in high-performance analog, mixed-signal, and digital signal processing semiconductors, serving industrial, automotive, communications, and consumer markets since 1965.

The MAX4389/MAX4390/MAX4392–MAX4396 family was designed specifically for high-fidelity analog video signal conditioning-emphasizing low differential gain/phase error, rail-to-rail drive, and compact packaging for space-constrained video equipment.

FAQ

Does MAX4392ESA+ support single-supply operation?

No, MAX4392ESA+ is specified for dual-supply operation only (±2.25V to ±5.5V). It does not support single-supply configurations like the MAX4389 or MAX4390. Attempting single-supply use violates the guaranteed input common-mode range and may result in degraded distortion performance or output saturation. For single-rail video applications, consider MAX4389ESA+ or MAX4390ESA+ instead.

What is the maximum capacitive load the MAX4392ESA+ can drive without instability?

The MAX4392ESA+ is not optimized for highly reactive loads. Driving >10pF directly risks peaking and oscillation. For loads exceeding 10pF (e.g., long traces or connectors), a series isolation resistor (10Ω–15Ω) must be placed between the output and capacitance. Figure 2 in the datasheet confirms this method eliminates ringing and maintains 0.1dB gain flatness up to 24MHz with 100pF loads when using 27Ω isolation.

Is MAX4392ESA+ pin-compatible with other devices in the MAX4389–MAX4396 family?

No, MAX4392ESA+ is not pin-compatible with other members. Its SO-8 pinout (OUTA, INA–, INA+, VEE, VCC, INB+, INB–, OUTB) differs from the SC70/SOT23 packages of MAX4389/MAX4390 and the μMAX/SO/TSSOP variants of MAX4393–MAX4396. Pin compatibility exists only within same-package variants (e.g., MAX4392ESA+ and MAX4392EUA+ share function mapping but differ in footprint).

What is the typical power dissipation of MAX4392ESA+ at ±5V supplies?

At ±5V supplies and TA = +25°C, MAX4392ESA+ draws 10mA total quiescent current (5mA per amplifier), resulting in ~100mW typical power dissipation (2 × 5mA × 5V). With θJA = 120°C/W, this yields ~12°C junction-to-ambient rise-well within safe limits for SO-8 packages on standard 2-layer PCBs with modest copper area.

Can MAX4392ESA+ be used in place of a video DAC output buffer in a broadcast monitor design?

Yes, MAX4392ESA+ is explicitly qualified for broadcast video applications. Its 0.015% differential gain and 0.015° differential phase error meet ITU-R BT.601 compliance thresholds. Paired with proper 75Ω termination and layout (microstrip routing, local 0.1μF bypassing), it preserves color fidelity and luma/chroma timing alignment required for professional monitor signal chains.
