MAX4246ASA+T

Instrumentation, Op Amps, Buffer Amps Overview

The MAX4246ASA+T is a dual-channel, low-power operational amplifier from the MAX4245/MAX4246/MAX4247 family. 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 52nV/√Hz input voltage noise density. The device features rail-to-rail inputs and outputs, ensuring full signal swing capability. It is specified for operation across an extended temperature range of -40°C to +125°C.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific package marking and ordering suffix against official manufacturer documentation to ensure correct component identification. Confirm that the device meets all required environmental specifications for the intended operating temperature range. Cross-reference the datasheet revision history to validate parameter accuracy before finalizing procurement decisions.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when space-constrained designs require dual amplifiers in an 8-pin SO package. It is suitable for battery-powered systems due to its low supply current and wide supply voltage range. Ensure the application does not require a shutdown mode, as this variant lacks that feature compared to other members of the MAX424x family.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MAX4245/MAX4246/MAX4247 series of ultra-small, rail-to-rail I/O op amps. While the MAX4245 offers a single amplifier and the MAX4247 provides a dual amplifier with shutdown functionality, the MAX4246 specifically delivers dual amplification without disable control. All variants share similar electrical characteristics and are designed for harsh environments.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

Direct substitutes within the same family include MAX4246AKA+T (SOT23-8) and MAX4246AUA+T (µMAX-8). These alternatives offer identical electrical performance but differ in physical package dimensions and pinout compatibility.
