Chopper-stabilized precision for low-level DC signals
The LTC1047CN8#PBF is a dual-channel chopper (zero-drift) operational amplifier from Analog Devices. Its internal auto-zero architecture holds input offset voltage to 3 µV. The 200 kHz gain-bandwidth product and 0.2 V/µs slew rate indicate DC-optimised performance.
Package and sourcing reality
The 8-DIP (0.300", 7.62 mm) through-hole package suits prototyping and wave-solder assembly. The supplier device package is 8-PDIP, and the part ships in a tube. Lifecycle status is Active with ROHS3 compliance.
Second-source and cross-shop context
The closest functional peer in the same commercial temperature band and through-hole footprint is the AD706JNZ, a general-purpose dual op-amp with 800 kHz GBW and 0.15 V/µs slew rate but a 30 µV offset — an order of magnitude higher than the LTC1047CN8#PBF. For a design that cannot tolerate that offset drift, the LTC1047CN8#PBF is the correct choice. The AD827JNZ and AD712KNZ are faster parts (50 MHz and 4 MHz respectively) with 300 µV offset, suited to different application tiers entirely.
