MAX4390EUK+T

Video Amps And Modules Overview

The MAX4390EUK+T is a single-channel, unity-gain stable voltage-feedback operational amplifier manufactured by Analog Devices. It operates from a single 4.5V to 11V supply or dual ±2.25V to ±5.5V supplies. Key electrical specifications include an 85MHz small-signal bandwidth, a 500V/μs slew rate, and a quiescent current of 5.5mA per amplifier. The device features rail-to-rail outputs, low differential gain/phase errors, and high output drive capability of ±50mA. It is housed in a compact 5-pin SOT-23 package.

Video Amps And Modules Procurement Notes

Verify the specific ordering suffix against official manufacturer documentation to ensure correct package type and tape-and-reel configuration. Confirm RoHS compliance status and lead-free material declarations directly with the supplier before procurement. Cross-reference the manufacturer part number with authorized distributor catalogs to validate authenticity and current production status.

Video Amps And Modules Selection Notes

Select this component when high-speed signal processing is required within a constrained physical footprint. The rail-to-rail output range makes it suitable for low-voltage single-supply designs. Ensure the application does not require a disable pin, as this specific variant lacks that feature compared to other family members like the MAX4389.

Video Amps And Modules Part Context

This device belongs to the MAX4389/MAX4390/MAX4392–MAX4396 family of ultra-small, low-cost op amps. While sharing core electrical characteristics such as bandwidth and slew rate, the MAX4390 specifically differs by lacking the disable functionality found in the MAX4389 and multi-channel variants. It is designed for cost-sensitive, space-constrained video and communication applications.

Video Amps And Modules Replacement Considerations

The MAX4389EUK+T serves as a functional substitute if the disable pin is unused, though pin compatibility must be verified. Other family members like the MAX4392 offer dual channels but differ in pin count and package options. Direct replacement requires matching the SOT-23-5 package and ensuring the absence of disable requirements in the circuit design.

Video Amps And Modules FAQ

Does the MAX4390EUK+T include a disable function?

No, the MAX4390 does not include a disable function. Only the MAX4389, MAX4393, MAX4394, and MAX4396 variants in this family feature the disable capability.

What is the input common-mode voltage range?

The input common-mode voltage range extends to the negative power-supply rail (VEE) and up to VCC minus 2.25V.
