Product details

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.

Package and sourcing reality

The 8-DIP (0.300", 7.62 mm) through-hole package suits prototyping and wave-solder assembly.

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.

Frequently asked questions

Does LTC1047CN8#PBF require a heat sink?

No. The total supply current for both channels is 80 µA, which keeps self-heating negligible at any rated supply voltage within the 0°C to 70°C operating range. No heatsink is needed.

What is the closest functional second-source to LTC1047CN8#PBF?

The AD706JNZ is a through-hole dual op-amp in the same temperature grade, but its 30 µV offset is ten times higher than the LTC1047CN8#PBF's 3 µV. For designs that can tolerate that drift, the AD706JNZ is a pin-compatible alternate; for precision DC applications, the LTC1047CN8#PBF remains the correct part.
