With the ±5 V input range, one LSB is 152.588 mV. 2See Definition of Specifications section. These specifications do not include the error contribution from the external reference. 3All specifications in dB are referred to a full-scale input FS. Tested with an input signal at 0.5 dB below full scale, unless otherwise specified. 4The max should be the minimum of 5.25 V and DVDD + 0.3 V. 5In Warp Mode. 6Tested in Parallel Reading Mode. 7Tested with the 0 V to 5 V range and V IN – VINGND = 0 V. See Power Dissipation section. 8In Impulse Mode. 9With OVDD below DVDD + 0.3 V and all digital inputs forced to DVDD or DGND, respectively. 10Contact factory for extended temperature range. Specifications subject to change without notice. Table I.
