Housed in an 8-SOIC package (0.154" body width, 3.90 mm), the ADA4857-1YRZ occupies a standard footprint compatible with automated pick-and-place assembly. This variant ships in tube form, not tape and reel — factor the tube-to-reel transfer if your line expects reel-fed feeders.
The part is ROHS3 compliant.
This specific order code (ADA4857-1YRZ) ships in tube packaging. A tape-and-reel variant may exist under a different suffix; check the manufacturer's ordering guide.
No official second-source cross-reference is recorded. Among the peer parts, the AD8056ARMZ offers a dual-channel voltage-feedback topology with 300 MHz bandwidth and 1400 V/µs slew rate, but it is not pin-compatible and has different supply requirements.
