MAX4246AKA-T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4246AKA-T is a dual-channel operational amplifier from the MAX4245/MAX4246/MAX4247 family, manufactured by Analog Devices Inc./Maxim Integrated. It operates on a single +2.5V to +5.5V supply or dual ±1.25V to ±2.75V supplies, consuming 320µA per amplifier. Key electrical parameters include a 1MHz gain-bandwidth product, 0.4V/µs slew rate, and unity-gain stability up to 470pF capacitive loads. The device features rail-to-rail input and output voltage swing, an input offset voltage of typically ±400µV, and operates within a temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific ordering suffix 'T' indicates tape-and-reel packaging configuration as defined in the manufacturer's documentation. Confirm that the 'KA' designation corresponds to the 8-pin SOT23 package variant. Ensure compliance with lead-free/RoHS standards if required by the application environment. Cross-reference the part number against the latest datasheet revision to confirm pinout and electrical specifications remain unchanged.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a dual-channel op amp with rail-to-rail I/O is required for battery-powered systems. It is suitable for applications needing low power consumption without shutdown functionality, unlike the MAX4245/MAX4247 variants. Consider the 8-pin SOT23 package constraints for space-limited designs. Verify that the 1MHz bandwidth and 0.4V/µs slew rate meet the signal processing requirements.

Instrumentation, Op Amps, Buffer Amps Part Context

This device belongs to the MAX4245/MAX4246/MAX4247 family of ultra-small, low-power operational amplifiers. While the MAX4245 and MAX4247 offer a shutdown mode, the MAX4246 variant lacks this feature but retains the core performance characteristics. The family is designed for harsh environments and single-supply operations, utilizing BiCMOS process technology for high precision and low noise.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct functional substitutes within the same package and specification profile are not explicitly listed in the provided documentation. Designers may evaluate other dual-channel rail-to-rail op amps from the manufacturer's portfolio, ensuring compatibility with the 8-pin SOT23 footprint and electrical limits.
