MAX4215ESA

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4215ESA is a precision, closed-loop voltage-feedback buffer featuring an enable control pin. It operates from a single 3.15V to 11V supply or dual supplies of ±1.575V to ±5.5V. The device provides a fixed internal gain of +2V/V in non-inverting configuration or -1V/V in inverting configuration. Key electrical parameters include a 600V/µs slew rate, a 230MHz small-signal bandwidth, and a 5.5mA quiescent supply current per buffer. When disabled, the supply current reduces to 400µA. The output stage supports rail-to-rail swing and delivers up to ±120mA drive current.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package marking and date code against the manufacturer's latest documentation before integration. Confirm that the EN_ pin logic thresholds align with the system's control voltage levels. Ensure power supply decoupling capacitors are placed close to the VCC and VEE pins to maintain stability and prevent oscillation during high-speed operation.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a single-channel buffer with precise gain settings and power management is required. The MAX4215 differs from the MAX4214 by including an enable pin, which allows for active power reduction. Consider the 8-pin SOIC package constraints regarding thermal dissipation and board space compared to other family members like the multi-channel MAX4217 or MAX4219.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4214/MAX4215/MAX4217/MAX4219/MAX4222 family of high-speed, single-supply buffers. These devices utilize current-feedback techniques to achieve wide bandwidths and fast slew rates while maintaining low distortion. The family covers configurations ranging from one to four channels, offering flexibility for various video and RF signal-processing applications requiring high performance.

Instrumentation, Op Amps, Buffer Amps FAQ

How does the MAX4215 handle input protection?

The device includes internal protection circuitry consisting of five back-to-back Schottky diodes between the IN+ and IN- terminals to prevent damage from large differential input voltages.

What is the effect of disabling the MAX4215?

When the EN_ pin is driven low, the buffer enters a shutdown state where the supply current per buffer drops to approximately 400µA.
