MC1458ID

Instrumentation, Op Amps, Buffer Amps Overview

The MC1458ID is a high-performance, monolithic dual operational amplifier manufactured by STMicroelectronics. It features two independent amplifiers within an 8-pin SO package designed for surface mount installation. The device supports a wide supply voltage range from -22 V to +22 V and operates reliably across temperatures from -40°C to 105°C. Key electrical specifications include a gain-bandwidth product of 1 MHz, a maximum input offset voltage of 6 mV, and an input bias current of 300 nA. The amplifier provides a slew rate of 0.8 V/μs and can deliver an output current of 35 mA.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix ID corresponds to the SO-8 surface mount package variant when sourcing. Confirm RoHS compliance status matches current manufacturing standards. Check for lead-free certification if required by assembly regulations. Ensure operating temperature range meets environmental constraints. Validate pinout compatibility with existing PCB footprints before finalizing procurement.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component for designs requiring dual op-amps with wide supply voltage flexibility. Consider the 1 MHz bandwidth limit for high-frequency signal processing tasks. Evaluate the 6 mV input offset voltage for precision requirements in low-level signal amplification. Assess the 300 nA bias current impact on high-impedance sensor interfaces. Compare thermal performance within the specified -40°C to 105°C range against ambient conditions.
