MC3403PT

Instrumentation, Op Amps, Buffer Amps Overview

The MC3403PT is a quad low-power operational amplifier manufactured by STMicroelectronics. It features four independent amplifiers with a gain-bandwidth product of 1 MHz and a slew rate of 500 mV/us. The device operates on supply voltages ranging from 3 V to 36 V single supply or ±1.5 V to ±18 V dual supply, with a quiescent current of 7 mA. Key electrical parameters include an input offset voltage of 5 mV, input bias current of 500 nA, common-mode rejection ratio of 70 dB, and power supply rejection ratio of 77 dB. It provides 30 mA output current per channel and has an input voltage noise density of 43 nV/sqrt Hz.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'PT' corresponds to the TSSOP-14 package and tape-and-reel shipping format as indicated by distributor listings. Confirm RoHS compliance status through official manufacturer documentation before integration. Ensure the selected variant matches the required operating temperature range for the target application environment.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when a cost-effective quad amplifier with UA741-like performance is needed but lower power consumption is required. It is suitable for designs requiring true differential inputs that include the negative rail. Consider the 1 MHz bandwidth limit for high-speed requirements and verify thermal management needs for the TSSOP-14 package.

Instrumentation, Op Amps, Buffer Amps Part Context

This part belongs to the MC3403 series of low-power quad operational amplifiers. It serves as a modern alternative to legacy devices like the UA741, offering similar electrical characteristics while supporting single-supply operation down to 3 Volts. The series is designed for general-purpose applications where moderate speed and low power are prioritized over precision or high-frequency performance.

Instrumentation, Op Amps, Buffer Amps Replacement Considerations

The MC3303PT is a related variant within the same family, typically offering extended industrial temperature ranges compared to the commercial grade MC3403PT. Verify pin compatibility and electrical specifications against the original design requirements before substitution.
