Buffer settling time adds to conversion speed when buffer is connected to input.
DTL/TTL compatible Logic 0 = 0.8 V max, Logic 1 = 2.0 V min for digital output, Logic 0 = 0.4 V max, Logic 1 = 2.4 V min.
Adjustable to zero.
FSR means full-scale range.
Guaranteed at VIN = 0 V.
Error shown is the same as ±1/2 LSB max error in % of FSR.
See Table 2.
For ±12 V operation, add Z to model number. Input range limited to a maximum of ±5 V.
For package outline information, see Outline Dimensions section.
