For a 100x gain stage, that translates to 200 µV of DC error at the output before any drift — negligible for most 12-bit systems and workable for 16-bit designs with careful layout. This makes the AD8555 a fit for thermocouple amplifiers, load-cell bridges, and photodiode transimpedance stages where the signal is in the millivolt range and DC accuracy matters. ## Package and rework: 16-LFCSP with exposed pad The 16-lead LFCSP (4x4 mm) with exposed pad is a common footprint for this class of precision amp, but it demands attention at assembly and rework. For hand rework, preheat the board to 150°C, apply flux, and use a hot-air nozzle sized for a 4x4 mm package; the part is small enough that the pad can lift if you dwell too long at 350°C.","metaTitle":"AD8555ACPZ-REEL7 Zero-Drift Amplifier, 2 µV Offset, 2 MHz","metaDescription":"ADI AD8555ACPZ-REEL7 zero-drift amplifier, 2 µV input offset, 2 MHz GBW, 1.2 V/µs slew rate, -40°C to 125°C, 16-LFCSP.
