(2) FSR means Full Scale Range. For example, for ±10V output, FSR = 20V. (3) Errors externally adjustable to zero. (4) Maximum represents the 3 σ limit. Not 100% tested for this parameter. (5) For the worst-case Binary Two’s Complement code changes: FFFF H to 0000H and 0000H to FFFFH. (6) During power supply turn on, the transient supply current may approach 3x the maximum quiescent specification. (7) Typical (i.e. rated) supply voltages times maximum currents. |
