NOTES: (1) LSB means Least Significant Bit. For the 12-bit,
±
2.5V input ADS7819, one LSB is 1.22mV. (2) Typical rms noise at worst case transitions and
temperatures. (3) Measured with 50
in series with analog input. Adjustable to zero with external potentiometer. (4) Full scale error is the worst case of –Full Scale
or +Full Scale untrimmed deviation from ideal first and last code transitions, divided by the transition voltage (not divided by the full-scale range) and includes the
effect of offset error. (5) All specifications in dB are referred to a full-scale
±
2.5V input. (6) Usable Bandwidth defined as Full-Scale input frequency at which Signal-
to-(Noise+Distortion) degrades to 60dB, or 10 bits of accuracy. (7) Recovers to specified performance after 2 x FS input over voltage.

DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from
performance degradation to complete device failure. Burr-
Brown Corporation recommends that all integrated circuits be
handled and stored using appropriate ESD protection
methods.
