Product details
Overview
MAX4019ESD+T from Maxim Integrated is a precision, closed-loop, gain-of-+2 (or -1) rail-to-rail output buffer with 200MHz -3dB bandwidth, 600V/µs slew rate, and integrated enable/disable control. It delivers ±120mA output drive, operates from +3.15V to +11V single supply, and targets high-fidelity video line driving and ADC interface applications requiring low differential gain/phase error (0.04%/0.02°).
For engineers reviewing the MAX4019ESD+T datasheet, MAX4019ESD+T pinout, MAX4019ESD+T application, or MAX4019ESD+T equivalent, key selection considerations include its 14-pin SO package, 400µA shutdown current, rail-to-rail output swing into 150Ω, and verified performance in NTSC video routing and high-speed analog front-end signal conditioning.
Technical Context
The MAX4019ESD+T implements voltage-feedback architecture enhanced with current-feedback techniques to achieve high slew rate and wide bandwidth while maintaining precision closed-loop gain stability. Its internal 500Ω precision resistors fix gain at +2 (noninverting) or -1 (inverting), eliminating external resistor matching requirements.
It features a dedicated EN_ pin that disables the amplifier core, reducing quiescent current to 400µA while raising output resistance to 1kΩ. Input voltage range extends 100mV beyond VEE, and output swing reaches within 60mV of rails into 2kΩ - critical for single-supply video signal fidelity.

Equivalent & Alternatives
The following parts are listed as comparable options for similar high-speed, rail-to-rail buffer applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| MAX4017ESA+ | Dual-channel, no enable pins; 8-pin SO package; 5.5mA ICC (no shutdown mode) | Lacks per-channel disable; unsuitable for power-gated multi-channel systems | Select when only two channels are needed and continuous operation is acceptable |
| THS3201D | Single-channel, 1.8GHz bandwidth, ±15V dual-supply only; no rail-to-rail output | Requires split supplies; higher power (12mA); not pin-compatible or functionally drop-in | Choose only for ultra-wideband (>500MHz) applications where MAX4019ESD+T bandwidth is insufficient |
Compared with MAX4017ESA+, MAX4019ESD+T adds enable control and a third channel but requires larger 14-pin SO layout; versus THS3201D, it trades bandwidth for single-supply operation, rail-to-rail swing, and integrated gain-setting resistors - making it optimal for cost-sensitive, space-constrained video and instrumentation designs.

FAQ
What is the operating supply voltage range for the MAX4019ESD+T?
The MAX4019ESD+T operates from a single +3.15V to +11V supply or dual ±1.575V to ±5.5V supplies. At +5V single supply, it delivers full 200MHz bandwidth and rail-to-rail output swing into 150Ω. Operation below +3.15V is not guaranteed per datasheet absolute maximum ratings and may degrade bandwidth and output drive capability.
Does the MAX4019ESD+T support gain-of-−1 configuration, and how is it implemented?
Yes, the MAX4019ESD+T supports gain-of-−1 via inverting configuration: connect the signal to IN− (e.g., Pin 2 for Amplifier A), ground IN+ (Pin 3), and take output from OUT (Pin 1). Internal 500Ω resistors set the gain precisely; for 50Ω systems, terminate the input with a 56Ω resistor to match source impedance and minimize reflections.
What is the typical disable time for the MAX4019ESD+T's enable feature?
The MAX4019ESD+T has a typical buffer disable time (tOFF) of 1ns when the EN_ pin transitions from logic-high to logic-low. This fast turn-off enables precise power gating in time-critical video blanking intervals or burst-mode data acquisition, minimizing leakage and crosstalk during inactive periods.
Can the MAX4019ESD+T drive a 50Ω load, and what is the resulting output swing?
Yes, the MAX4019ESD+T can drive a 50Ω load with ±120mA output capability. At +5V supply, it delivers up to 1.6V peak-to-peak swing (40mV above VEE to 3.4V below VCC). For full-scale 1VPP video signals, this provides >6dB headroom - sufficient for NTSC/PAL composite video without clipping or distortion.
How does the MAX4019ESD+T handle capacitive loads, and what isolation resistance is recommended for 100pF?
The MAX4019ESD+T remains stable with ≤25pF capacitive load directly. For 100pF, an isolation resistor (RISO) of 27Ω is recommended per Figure 8 in the datasheet. This resistor, placed in series with the output, suppresses peaking and maintains phase margin - verified by flat small-signal response up to 100MHz with 100pF + 27Ω per Figure 9.
