FO is the AD1556 output word rate, the inverse of the sampling rate. See Tables I, Ia, Ib for other output word rates. 2Tested with a full-scale input signal at approximately 24 Hz. 3This parameter is guaranteed by design. 4Tested at the output word rate FO = 1 kHz with input signals of 30 Hz and 50 Hz, each 6 dB down full scale. 5This specification is for the AD1555 only and does not include the errors from external components as, for instance, the external reference. 6This offset specification is referred to the modulator output. 7Characterized with a 100 mV p-p sine wave applied separately to each supply. 8Contact factory for extended temperature range. 9Recommended Reference: AD780BR. 10Specified with analog inputs grounded. 11See Table III for configuration conditions. 12Specified with MCLK input grounded. Specifications subject to change without notice.
