Terminology
3 Analog inputs with slew rates exceeding 27 V/s (full-scale input sine wave > 3.5 MHz) within the acquisition time may cause an incorrect result to be returned by the
converter.
4 A small dc input is applied to VIN– to provide a pseudo ground for VIN+.
5 The AD7453 is functional with a reference input in the range 100 mV to VDD.
6 Guaranteed by characterization.
7 See

Power vs. Throughput Rate
8 Measured with a full-scale dc input.
