High-side current sensing with ±0.01% accuracy
The Texas Instruments INA216A1YFFR is a high-side current shunt monitor from the Zero-Drift series, delivering a typical accuracy of ±0.01% — this is the figure that governs the measurement error budget in a precision power-monitoring or battery-management channel.
Package and board-fit for the 4-DSBGA
Housed in a 4-bump UFBGA (DSBGA) package, the INA216A1YFFR requires a 4-layer PCB for fan-out — the 0.50 mm pitch bumps do not route cleanly on a two-layer board. The supplier device package is 4-DSBGA, which is the same physical footprint as the 4-UFBGA case code. Because the package is a wafer-level chip-scale (DSBGA), the solder-joint reliability depends on the board-side pad geometry matching TI's recommended land pattern.
For a BOM line that requires a high-side current monitor with this accuracy class, the INA216A1YFFR is a single-source item within the Zero-Drift series — no pin-compatible second source is published.
