Product details
Overview
MAX4219EEE+ from Maxim Integrated is a triple-channel, high-speed, closed-loop rail-to-rail buffer with enable, configured for fixed +2V/V or −1V/V gain. It delivers 230MHz −3dB bandwidth, 600V/µs slew rate, ±120mA output drive, and 0.03%/0.04° differential gain/phase error. It operates from a single 3.15V–11V supply and is used in video routing, CCD imaging, and ADC interface circuits.
For engineers reviewing the MAX4219EEE+ datasheet, MAX4219EEE+ pinout, MAX4219EEE+ application, or MAX4219EEE+ equivalent, key selection criteria include its triple-amplifier architecture with independent enable control, QSOP-16 package footprint, rail-to-rail output swing under 150Ω load, and verified 90MHz 0.1dB gain flatness for NTSC video fidelity.
Technical Context
The MAX4219EEE+ implements voltage-feedback topology enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining precision closed-loop gain via internal 500Ω resistors. Its three independent amplifiers share a common VCC/VEE supply but feature separate ENA/ENB/ENC logic inputs for per-channel shutdown.
Each channel supports noninverting (+2V/V) or inverting (−1V/V) configuration without external gain-setting resistors. Input common-mode range extends 100mV beyond VEE, and output swings rail-to-rail into 2kΩ, with reduced swing into 150Ω (typ. 4.0VP-P at 5V supply). Shutdown reduces quiescent current to 400µA per amplifier.
Key Specifications
| Parameter | Value and Actual Design Meaning |
|---|---|
| Bandwidth (−3dB) | 230MHz - supports full HD video baseband signal integrity up to ~100MHz fundamental |
| Slew Rate | 600V/µs - enables clean 2VP-P step response in <1ns, critical for fast video pulse fidelity |
| Output Drive | ±120mA - drives 75Ω coaxial lines or multiple 150Ω loads without external buffering |
| Differential Gain/Phase Error | 0.03%/0.04° - meets broadcast-grade NTSC/PAL video linearity requirements |
| Supply Current (active) | 5.5mA per amplifier - total 16.5mA for all three channels at 25°C, enabling low-power multi-channel systems |
| Shutdown Current | 400µA per amplifier - reduces total system idle power to <1.2mA when unused channels disabled |
| Input Noise Density | 10nV/√Hz - preserves SNR in low-level analog front-ends such as CCD sensor interfaces |
Pinout & Package
The MAX4219EEE+ is housed in a 16-pin QSOP package (5.3mm × 10.2mm, 0.635mm pitch), optimized for space-constrained video routing PCBs and compatible with standard surface-mount reflow profiles.
| Pin/Terminal | Circuit Role | Design Meaning |
|---|---|---|
| 1, 2, 3, 4, 5, 6, 7, 8 | INA−, INA+, INB−, INB+, INC−, INC+, VEE, VCC | Per-amplifier differential inputs and shared dual-rail supply pins; VEE serves as ground reference in single-supply mode |

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, multi-channel buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4219ESD+ | Same electrical specs; packaged in 14-pin SO instead of 16-pin QSOP - 1.27mm vs. 0.635mm pitch, larger footprint | Preferred where through-hole prototyping or legacy SO footprints exist; less suitable for dense video routing boards | Select MAX4219ESD+ only if board layout requires SO package compatibility or thermal mass for higher ambient operation |
| THS3203DGN | Single-channel, 1.8GHz bandwidth, no integrated gain resistors - requires external 500Ω network for +2V/V; higher 12mA supply current | Better for ultra-wideband RF IF stages; lacks per-channel enable and differential gain spec for video compliance | Choose THS3203DGN only when >500MHz bandwidth is mandatory and external gain setting is acceptable |
Compared with MAX4219ESD+ and THS3203DGN, the MAX4219EEE+ uniquely combines triple-channel integration, factory-trimmed +2/−1 gain, video-optimized distortion performance, and QSOP-16 space efficiency-making it optimal for compact, multi-source video systems requiring guaranteed NTSC fidelity.

FAQ
What is the operating supply voltage range for the MAX4219EEE+?
The MAX4219EEE+ operates from a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. In single-supply mode, VEE is tied to ground and VCC accepts 3.15V–11V. This range supports both 3.3V and 5V systems while maintaining full rail-to-rail output swing and 230MHz bandwidth. The MAX4219EEE+ is fully specified across −40°C to +85°C.
Does the MAX4219EEE+ require external resistors to set gain?
No, the MAX4219EEE+ does not require external resistors to set gain. It uses internal precision 500Ω resistors to provide fixed closed-loop gains of +2V/V (noninverting) or −1V/V (inverting). This eliminates gain-setting component count, improves temperature stability, and reduces layout sensitivity-critical for consistent video signal path performance in the MAX4219EEE+.
How many amplifiers are integrated in the MAX4219EEE+ and how is enable controlled?
The MAX4219EEE+ integrates three independent high-speed amplifiers. Each has dedicated enable inputs: ENA (pin 14), ENB (pin 13), and ENC (pin 12). Driving any ENx pin to VEE disables its corresponding amplifier, reducing its quiescent current to 400µA. This per-channel control enables dynamic power management in multi-path video switchers without affecting other active channels in the MAX4219EEE+.
What is the maximum capacitive load the MAX4219EEE+ can drive without instability?
The MAX4219EEE+ is stable driving up to 20pF of capacitive load without external compensation. Beyond 20pF, peaking and potential oscillation may occur due to phase margin degradation. For loads >20pF (e.g., long PCB traces or connector parasitics), a series isolation resistor (e.g., 27Ω) between the MAX4219EEE+ output and the load restores stability while preserving bandwidth-verified in Figure 9 of the datasheet.
Is the MAX4219EEE+ pin-compatible with other members of the MAX421x family?
No, the MAX4219EEE+ is not pin-compatible with MAX4214/MAX4215/MAX4217 due to differing channel counts and pinouts. The MAX4219EEE+ uses a 16-pin QSOP with dedicated ENA/ENB/ENC and three output pins, whereas MAX4217 (dual-channel) uses 14-pin SO or 16-pin QSOP with different pin assignments. Always verify pin mapping using the "Pin Configurations" section of the MAX4219EEE+ datasheet before board design.
