(1)

Minimum values for ADS41B49 are specified across the ambient temperature range of –40°C to +105°C.

(2)

The maximum DRVDD current with CMOS interface depends on the actual load capacitance on the digital output lines. Note that the

maximum recommended load capacitance on each digital output line is 10 pF.

(3)

In CMOS mode, the DRVDD current scales with the sampling frequency, the load capacitance on output pins, input frequency, and the

supply voltage (see the CMOS Interface Power Dissipation section in the Feature Description).

6.5 Electrical Characteristics: General

Typical values are at TA = 25°C, AVDD = 1.8 V, AVDD_BUF = 3.3 V, DRVDD = 1.8 V, and 50% clock duty cycle, unless

otherwise noted. Minimum and maximum values are across the full ambient temperature range: TA, MIN = –40°C to TA, MAX =

85°C, AVDD = 1.8 V, AVDD_BUF = 3.3 V, and DRVDD = 1.8 V, unless otherwise noted.
