Product details
Overview
The MAX4117ESA-TG068 from Maxim Integrated is a dual-channel, low-power current-feedback operational amplifier optimized for closed-loop gains ≥2V/V, delivering 400MHz -3dB small-signal bandwidth, 1200V/µs slew rate, and ±3.5V output swing into 100Ω - enabling high-fidelity RGB video line driving and pulse amplification in broadcast and professional camera systems.
For engineers reviewing the MAX4117ESA-TG068 datasheet, MAX4117ESA-TG068 pinout, MAX4117ESA-TG068 application, or MAX4117ESA-TG068 equivalent, key selection criteria include gain-flatness-critical video signal integrity, dual-channel channel-to-channel crosstalk <−100dB at 10MHz, full-power bandwidth up to 280MHz (2VP-P), and SO-8 package compatibility with ±5V dual-supply industrial video signal chains.
Technical Context
The MAX4117ESA-TG068 implements a current-feedback architecture with transimpedance open-loop gain (ZOL = 500kΩ typical), where bandwidth remains stable across closed-loop gains ≥2V/V due to low input impedance (~30Ω) at the inverting node. Its internal biasing supports operation from ±4.5V to ±5.5V supplies.
It features matched dual amplifiers sharing common VCC and VEE rails, with independent IN+/IN−/OUT per channel and no internal inter-channel coupling beyond specified crosstalk (−100dB @ 10MHz). Input stage design minimizes differential gain/phase error (0.02%/0.03°) for NTSC/PAL-compliant video buffering.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| -3dB Bandwidth | 400MHz at AVCL ≥2V/V - enables baseband RGB video (up to ~170MHz fundamental) with ≤0.1dB gain variation |
| Slew Rate | 1200V/µs - supports clean 2VP-P pulse edges with <3ns rise/fall times (10%–90%) |
| Output Drive | ±3.5V into 100Ω load - meets 75Ω coaxial line drive requirements with headroom for sync pulses |
| Supply Current | 5mA per amplifier - enables dual-channel operation at <10mA total, critical for thermally constrained video modules |
| Differential Gain/Phase | 0.02% / 0.03° - satisfies broadcast-grade video fidelity (SMPTE RP-168, ITU-R BT.601) |
| Input Offset Voltage | 1mV max - ensures DC-coupled video paths maintain black-level accuracy without clamping circuitry |
| 0.1dB Gain Flatness | 115MHz - guarantees flat frequency response across HD video bandwidth (e.g., 1080p/60) |
Pinout & Package
MAX4117ESA-TG068 uses an 8-pin SO (Small Outline) package (S8-2), 150mil body width, with exposed pad not electrically connected. Pin 1 is marked by notch or dot; device operates with VCC on pin 4 and VEE on pin 5.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1 | OUTA | Amplifier A output - drives first video channel or primary signal path; requires local 1000pF + 0.01µF bypass to ground |
| 2 | INA− | Inverting input of Amp A - low-impedance node (≈30Ω); connects to feedback network (RF) and gain-setting resistor (RG) |
| 3 | INA+ | Noninverting input of Amp A - high-impedance node; connects to source (e.g., DAC output or preceding buffer) |
| 4 | VCC | Positive supply rail (+5V) - must be decoupled within 2mm of pin using 1000pF ceramic + 0.01µF ceramic in parallel |
| 5 | INB+ | Noninverting input of Amp B - isolated from Amp A; used for second video channel or auxiliary signal |
| 6 | INB− | Inverting input of Amp B - identical electrical behavior to INA−; maintains channel independence |
| 7 | OUTB | Amplifier B output - drives second video channel (e.g., Y/C separation or stereo audio summing) |
| 8 | VEE | Negative supply rail (−5V) - symmetric dual supply required; same decoupling as VCC |
Key Features
| Feature | Design Value |
|---|---|
| 400MHz −3dB bandwidth at AVCL ≥2V/V | Enables distortion-free amplification of 1080p60 RGB signals without external equalization |

Equivalent & Alternatives
The following parts are listed as comparable options for similar dual-channel current-feedback amplifier applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| THS3202D | Higher supply current (11mA/ch), wider 1.8GHz bandwidth, but only 0.05% DG error and no guaranteed 0.1dB flatness spec | Preferred for RF/IF gain blocks >500MHz; less suitable for broadcast video due to higher distortion at 10–100MHz | Select THS3202D only when >1GHz small-signal BW is mandatory and power budget allows +120% quiescent current |
| LMH6702MA | Lower power (3.5mA/ch), 1.8GHz BW, but 0.1dB flatness only to 70MHz and no differential gain/phase characterization | Better for generic high-speed analog front-ends; lacks video-specific validation for NTSC/PAL/HD-SDI | Choose LMH6702MA for cost-sensitive instrumentation where video fidelity specs are non-binding |
Compared with THS3202D and LMH6702MA, the MAX4117ESA-TG068 uniquely balances broadcast-grade video linearity (0.02% DG), 400MHz bandwidth, and 5mA/ch power - making it the only option qualified for SMPTE-compliant RGB distribution without external trimming or calibration.

FAQ
What is the maximum closed-loop gain supported by the MAX4117ESA-TG068 without bandwidth degradation?
The MAX4117ESA-TG068 is optimized for closed-loop gains of 2V/V or greater. At AVCL = +2, it delivers full 400MHz −3dB bandwidth and 115MHz 0.1dB gain flatness. Gains below +2 cause peaking and instability; gains ≥+2 maintain flat response and phase margin. The datasheet explicitly states "optimized for closed-loop gains of 2V/V or greater", and performance degrades outside this range.
Does the MAX4117ESA-TG068 support single-supply operation?
No, the MAX4117ESA-TG068 requires dual ±5V supplies (±4.5V to ±5.5V specified). Its input common-mode range is ±2.5V and output swing is ±3.5V into 100Ω - both referenced to ground, necessitating symmetric rails. Single-supply use violates absolute maximum ratings and causes clipping or latch-up.
What is the channel-to-channel crosstalk specification for the MAX4117ESA-TG068?
The MAX4117ESA-TG068 exhibits −100dB crosstalk at 10MHz, measured per Figure 18a in the datasheet. This value is confirmed across the operating temperature range (−40°C to +85°C) and applies to both forward (OUTA → INB) and reverse (OUTB → INA) coupling paths under standard ±5V supply conditions.
Can the MAX4117ESA-TG068 drive a 75Ω coaxial cable directly?
Yes - the MAX4117ESA-TG068 is characterized to drive 75Ω loads with 0.02% differential gain error and 0.03° differential phase error, as shown in Figure 31/32. It delivers ±3.5V into 100Ω, exceeding the 1VP-P requirement for 75Ω video lines. Termination should be at the load end; no series resistor is needed for basic operation.
Is the MAX4117ESA-TG068 pin-compatible with other devices in the MAX411x family?
Yes - the MAX4117ESA-TG068 shares the identical 8-pin SO (S8-2) pinout with MAX4112ESA, MAX4113ESA, and MAX4118ESA. All use pins 1–3 and 5–7 for OUTA/INA−/INA+/INB+/INB−/OUTB, with VCC on pin 4 and VEE on pin 5. However, internal optimization differs: MAX4117/MAX4112 target AVCL ≥2V/V, while MAX4113/MAX4118 target AVCL ≥8V/V.
