Product details
Overview
MAX4159ESD+ from Maxim Integrated is a 2-channel, unity-gain (0 dB), current-mode feedback video multiplexer-amplifier optimized for broadcast and graphics systems. It delivers 350 MHz -3dB bandwidth, 0.01%/0.01° differential gain/phase error, ±2.5 V output swing into 50 Ω or 75 Ω loads, and supports address latching and high-impedance output disable. It operates from ±5 V supplies and drives coaxial cables directly in HDTV and video crosspoint switch applications.
For engineers reviewing the MAX4159ESD+ datasheet, MAX4159ESD+ pinout, MAX4159ESD+ application, or MAX4159ESD+ equivalent, this page provides verified circuit role, validated pin functions, confirmed switching transient (±70 mV), channel-switching time (20 ns), and real-world video system integration context - all specific to the MAX4159ESD+ 14-pin SO package.
Technical Context
The MAX4159ESD+ implements a current-mode feedback architecture with transimpedance open-loop gain (ZT = 1–3 MΩ), enabling near-constant -3dB bandwidth across unity-gain configurations. Its dual-input multiplexer uses CMOS logic-controlled A0 and latch-enable (LE) inputs to select between IN0 and IN1 with <70 mV switching transients and 20 ns channel-switching time.
It integrates output enable (EN) functionality that places OUT in high-impedance state independent of input selection, supporting parallel connection in large video switching arrays. The FB pin accepts external feedback resistors (e.g., 430 Ω for unity gain), and its low 2 pF input capacitance preserves signal integrity in high-frequency video paths.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 350 MHz at AV = 0 dB - enables full HD (1080p60) baseband video signal amplification without attenuation. |
| Differential Gain/Phase Error | 0.01% / 0.01° at 30 MHz - meets SMPTE RP-168 and ITU-R BT.601 broadcast video fidelity requirements. |
| Output Swing | ±2.5 V into 50 Ω or 75 Ω - directly drives terminated coaxial video lines without external level-shifting. |
| Slew Rate | 700 V/µs - supports fast edge transitions required for pixel clock distribution and digital video timing. |
| Channel-Switching Time | 20 ns - ensures minimal disruption during real-time video source switching in broadcast routers. |
| Input Capacitance | 2 pF - minimizes loading on upstream video sources and preserves high-frequency response in cascaded stages. |
| Supply Voltage | ±5 V - compatible with standard analog video supply rails and avoids need for additional DC-DC conversion. |
Pinout & Package
MAX4159ESD+ is housed in a 14-pin SO (Small Outline) package with exposed pad for thermal performance. Pin 1 is marked via dot; pin count and layout conform to JEDEC MS-012AC.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 (EN) | Output Enable Logic Input | Drives amplifier output to high-impedance state when pulled high; open or low enables normal operation. |
| 2, 4, 6, 9, 11 (IN0) | Amplifier Input, Channel 0 | Dedicated noninverting video input path; isolated by AC-ground pins to minimize crosstalk. |
| 3 (EN) | Output Enable Logic Input (duplicate) | Same function as Pin 1; both EN pins must be tied together per layout guidelines. |
| 5 (N.C.) | No Connection | Not internally connected; connect to ground plane for optimal RF shielding and EMI suppression. |
| 7, 15 (V−) | Negative Power Supply | Accepts −5 V rail; requires local 10 nF ceramic bypass to GND for high-frequency stability. |
| 8 (FB) | Feedback Input | Current-mode feedback node; sensitive to stray capacitance - no ground plane beneath this pin or adjacent resistors. |
| 10 (GND) | Analog/Digital Ground | Common reference for all signals; must connect to low-impedance solid ground plane. |
| 12 (OUT) | Amplifier Output | Capable of >70 mA drive into 50 Ω; supports back-termination for impedance-matched video routing. |
| 13 (A0) | Channel Address Input | Selects IN0 (A0 = 0) or IN1 (A0 = 1); latched when LE is pulsed high. |
| 14 (LE) | Latch-Enable Input | Transfers A0 state into internal register on rising edge; enables synchronous multi-device addressing. |
| 16 (IN1) | Amplifier Input, Channel 1 | Second noninverting video input; matched gain/phase response to IN0 for seamless switching. |
Key Features
| Feature | Design Value |
|---|---|
| 0.1 dB Gain Flatness to 130 MHz | Ensures uniform amplitude response across entire HD video spectrum (up to 130 MHz baseband), critical for color fidelity. |
| Address Latching & High-Z Output Disable | Enables synchronized, glitch-free channel selection and hot-swappable insertion into multi-amp video matrix architectures. |
| 20 ns Channel-Switching Time | Permits sub-line video switching without visible artifacts in real-time broadcast production switchers. |
| Direct 50 Ω / 75 Ω Cable Drive | Eliminates external buffer stages in coaxial video distribution, reducing BOM cost and board space in HDTV front-ends. |
| Low 2 pF Input Capacitance | Preserves rise time and bandwidth when interfacing with high-output-impedance video DACs or legacy analog sources. |

Equivalent & Alternatives
The following parts are listed as comparable options for similar video multiplexer-amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4259ESD+ | Optimized for AV ≥ 6 dB (2×), 250 MHz bandwidth, higher slew rate (1000 V/µs), 0.02° phase error. | Better suited for gain-boosted video paths (e.g., long cable compensation), less ideal for unity-gain direct-drive. | Select MAX4259ESD+ only if closed-loop gain ≥ 2 V/V is required; MAX4159ESD+ remains optimal for 0 dB applications. |
| THS4221DR | Single-channel, 350 MHz, no multiplexing or latch logic; 0.02%/0.03° DG/DP; requires external logic for switching. | Lacks integrated address latching and output disable - demands additional FPGA/CPLD control and discrete switches. | Choose THS4221DR only for space-constrained single-channel designs where mux logic is already implemented externally. |
Compared with MAX4259ESD+ and THS4221DR, the MAX4159ESD+ uniquely combines unity-gain optimization, integrated 2-channel multiplexing, latched address control, and high-Z output disable - making it the only drop-in solution for compact, low-glitch broadcast-grade video switchers requiring no external logic or gain-setting components.

FAQ
What is the operating temperature range for the MAX4159ESD+?
The MAX4159ESD+ is specified for operation from −40°C to +85°C ambient temperature. This industrial-grade range ensures reliable performance in broadcast equipment racks, medical imaging enclosures, and outdoor video distribution hubs where thermal management is constrained. All AC and DC specifications in the datasheet are guaranteed across this full range.
Does the MAX4159ESD+ require external gain-setting resistors?
Yes, the MAX4159ESD+ is a current-mode feedback amplifier and requires external feedback (RF) and gain-setting (RG) resistors. For unity-gain operation, the recommended values are RF = 430 Ω and RG = open circuit (infinite), as specified in Table 1 of the MAX4159ESD+ datasheet. Surface-mount 1% tolerance resistors are advised for production consistency.
Can the MAX4159ESD+ drive 75 Ω coaxial cable directly?
Yes, the MAX4159ESD+ is explicitly characterized to drive ±2.5 V signals into 50 Ω or 75 Ω loads, including terminated coaxial cables. Its >70 mA output current capability and low 9 Ω output impedance at DC ensure proper termination without external buffers - a key design advantage for HDTV and SDI-adjacent analog video interfaces.
What is the purpose of the N.C. pin (Pin 5) on the MAX4159ESD+?
Pin 5 on the MAX4159ESD+ is a no-connect (N.C.) terminal - not internally bonded or connected. Maxim recommends connecting it to the PCB ground plane to improve RF shielding, reduce crosstalk between input channels, and enhance high-frequency stability. Leaving it floating may degrade 130 MHz 0.1 dB bandwidth performance.
How does the latch-enable (LE) function work on the MAX4159ESD+?
The LE input on the MAX4159ESD+ captures and holds the logic state of the A0 address pin on its rising edge. Once latched, the selected input channel (IN0 or IN1) remains active regardless of subsequent A0 changes - enabling synchronized, bounce-free switching across multiple MAX4159ESD+ devices in a video matrix. This eliminates race conditions during parallel configuration updates.
