RC4559PG4

Instrumentation, Op Amps, Buffer Amps Overview

The RC4559PG4 is a dual high-performance operational amplifier manufactured by Texas Instruments. It features a gain-bandwidth product of 4 MHz and a slew rate of 2 V/us. The input offset voltage is specified at 6 mV, with an input bias current of 250 nA. Operating from a single supply of 10 V to 30 V or dual supplies of ±5 V to ±15 V, it draws 3.3 mA of supply current per channel. Each channel provides an output current of 10 mA. The device offers a common-mode rejection ratio of 100 dB and an input voltage noise density of 7 nV/sqrt Hz. It is housed in an 8-pin PDIP package.

Instrumentation, Op Amps, Buffer Amps Procurement Notes

Verify the specific suffix 'G4' against the manufacturer's official documentation to confirm RoHS compliance status and exact pinout compatibility. Ensure the procurement source provides valid traceability data. Confirm that the PDIP-8 package matches the target PCB footprint requirements before finalizing orders.

Instrumentation, Op Amps, Buffer Amps Selection Notes

Select this component when high performance metrics such as low noise and high CMRR are required over general-purpose alternatives. Compare the 4 MHz bandwidth and 2 V/us slew rate against application signal frequencies. Verify that the 10 mA output current meets load demands. Consider the PDIP package constraint if surface-mount assembly is preferred.

Instrumentation, Op Amps, Buffer Amps Part Context

The RC4559 series represents Texas Instruments' high-performance operational amplifiers, distinct from the standard RC4558 general-purpose line. This family targets applications requiring superior noise performance and higher common-mode rejection ratios. The PG4 variant specifically denotes the lead-free, RoHS-compliant version of the standard PDIP-8 packaged device within this high-performance category.
