1 Multiplexer input voltage should not exceed VDD.
2 Sample tested during initial release to ensure compliance.
3 When referring to a single function of a multifunction pin in the parameters, only the portion of the pin name that is relevant to the specification is listed. For full pin
names of multifunction pins, refer to the Pin Configurations and Function Descriptions section.
4 Device is functional and meets dynamic performance/dc accuracy specifications with VDRIVE down to 1.8 V, but the device is not capable of achieving a throughput of
1 MSPS.
5 SCLK operates in burst mode, and CS idles high. With a free running SCLK and CS pulled low, the IDD static current is increased by 30 µA typical at VDD = 5.25 V.
6 SCLK operates in burst mode, and CS idles high. With a free running SCLK and CS pulled low, the IDRIVE static current is increased by 32 µA typical at VDRIVE = 5.25 V.
7 Total power dissipation includes contributions from VDD, VDRIVE, and REFIN (see Note 2).
