NOTES
1Temperature ranges are as follows: J Grade: 0
°C to +70°C, S Grade: –55°C to +125°C.
2Adjustable to zero with external potentiometers (see Zero and Gain Error Calibration section).
3+25
°C to T
MIN and +25°C to TMAX.
4Includes internal voltage reference error.
5Excludes internal reference drift.
6Change in Gain Error as a function of the dc supply voltage (V
NOMINAL to VMIN, VNOMINAL to VMAX).
7LCC package only.
Specifications subject to change without notice.
(TMIN to TMAX with AVDD = +5 V, DVDD = +5 V, DRVDD = +5 V, AVSS = –5 V, fSAMPLE = 5 MHz, unless otherwise
noted)
