MC33503SNT1

Instrumentation, Op Amps, Buffer Amps Overview

The MC33503SNT1 is a standard general-purpose operational amplifier manufactured by onsemi, belonging to the SMARTMOS series. It features three independent circuits within a single package, housed in an 8-TSSOP surface-mount case. The device supports a supply voltage span ranging from 1 V to 7 V and operates across a temperature range of -40°C to 105°C. Key electrical specifications include a gain-bandwidth product of 4 MHz, a slew rate of 3V/µs, and an input bias current of 0.04 pA. It delivers an output current of 70 mA per channel with full-swing output capability and maintains an input offset voltage of 500 µV.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify component authenticity through authorized distributors or direct manufacturer channels. Confirm the specific suffix matches the required package variant. Check for RoHS compliance status as historical data indicates potential non-compliance for older batches. Ensure the operating environment stays within the specified -40°C to 105°C temperature range for reliable performance.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when multiple identical amplifier functions are required in a space-constrained design. It is suitable for applications demanding low power consumption and operation from single low-voltage supplies. Compare against the single-circuit MC33501 if only one channel is needed to optimize cost and board area.

Instrumentation, Op Amps, Buffer Amps Part Context

This part is part of the MC3350x family of operational amplifiers, which includes single (MC33501) and dual (MC33502) variants. The MC33503 specifically provides triple amplification capabilities. These devices utilize SMARTMOS technology to achieve high performance with low power consumption, making them suitable for battery-operated consumer electronics and industrial control systems requiring multiple signal paths.
