MAX4219ESD

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4219ESD is a high-speed, single-supply, closed-loop buffer featuring three amplifiers with an internal gain of +2V/V or -1V/V. It operates on a single 3.15V to 11V supply or dual ±1.575V to ±5.5V supplies. Key electrical parameters include a 600V/µs slew rate, 230MHz bandwidth, and 5.5mA quiescent current per amplifier. The device includes an enable feature reducing current to 400µA when disabled. It offers rail-to-rail output swing, input common-mode range extending beyond the negative rail, and low differential gain/phase error.

Instrumentation, Op Amps, Buffer Amps Feature Summary

• Internal precision resistors provide fixed closed-loop gains of +2V/V or -1V/V without external components.
• High-speed performance characterized by a 600V/µs slew rate and 230MHz bandwidth for wideband signal processing.
• Enable pin functionality allows switching between active mode (5.5mA) and low-power shutdown mode (400µA).
• Rail-to-rail output capability with input common-mode voltage extending 100mV below the negative supply rail.

Instrumentation, Op Amps, Buffer Amps Applications

• Video line drivers
• Analog-to-digital converter interfaces
• CCD imaging systems
• Video routing and switching systems

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'ESD' corresponds to the 14-pin SO package and industrial temperature range (-40°C to +85°C) as listed in the ordering information. Confirm that the component is sourced from authorized distributors to ensure authenticity. Check for any recent product change notices regarding lead material or packaging updates. Ensure design-in compatibility with existing PCB footprints for the 14-SO package.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for applications requiring multiple high-speed buffers with fixed gain configurations. The integrated enable feature makes it suitable for power-sensitive systems requiring periodic shutdown. Consider the 14-pin SO package constraints if space is limited. Evaluate the need for three independent channels versus using single-channel alternatives to optimize board space and cost.

Instrumentation, Op Amps, Buffer Amps Part Context

The MAX4219 belongs to the MAX4214 family of high-speed, single-supply, closed-loop buffers. This family includes variants with one, two, three, or four amplifiers. The MAX4219 specifically integrates three amplifiers, each capable of a gain of +2V/V or -1V/V. It shares features like rail-to-rail outputs and high slew rates with siblings such as the MAX4214 and MAX4222.
