Test Conditions/Comments

VDRIVE < 1.8

VDRIVE ≥ 1.8

For VIN0 to VIN7 with one cycle latency

Full-scale step input

fSCLK = 20 MHz; for analog voltage

conversions, one cycle latency

Digital inputs = 0 V or VDRIVE

VDD = 3.6 V, VDRIVE = 3.6 V

TA = −40°C to +25°C

TA = −40°C to +125°C

VDD = 3 V, VDRIVE = 3 V

TA = −40°C to +25°C

TA = −40°C to +125°C

1 All specifications expressed in decibels are referred to full-scale input FSR and tested with an input signal at 0.5 dB below full scale, unless otherwise specified.

2 See the Terminology section.

3 Sample tested during initial release to ensure compliance.

4 Refers to the VREF pin specified for 25°C.

5 ITOTAL is the total current flowing in VDD and VDRIVE.

6 Power dissipation is specified with VDD = VDRIVE = 3.6 V, unless otherwise noted.
