Note 2: In single supply, INL and GE are calculated from code 11 to code 4095.
Note 3: Zero Code, Bipolar and Gain Error PSRR are input referred specifications. In Unity Gain, the specification is 500µV.
In Gain = 2 and Bipolar modes, the specification is 1mV.
Note 4: Guaranteed by design.
Note 5: REFIN = 1kHz, 2.0Vp-p.
Note 6: For specified performance, V
DD
= 5V ±10% is guaranteed by PSRR tests.
Note 7: For specified performance, V
SS
= -5V ±10% is guaranteed by PSRR tests.
Note 8: Tested at I
OUT
= 100µA. The reference can typically source up to 5mA (see Typical Operating Characteristics ).
