With the 0 V to 2.5 V input range, 1 LSB is 38.15 µV. 3See Definitions of Specifications section. These specifications do not include the error contribution from the external reference. 4All 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. 5Parallel or Serial 16-Bit. 6Conversion results are available immediately after completed conversion. 7 The max should be the minimum of 5.25 V and DVDD + 0.3 V. 8 With REF, PDREF and PDBUF are LOW; without REF, PDREF and PDBUF are HIGH. 9 With PDREF, PDBUF LOW and PD HIGH. 10 Tested in parallel reading mode 11Consult factory for extended temperature range. |
