NOTES: (1) LSB means Least Significant Bit. For the 12-bit, 0 to +5V input ADS7820, one LSB is 1.22mV. (2) Typical rms noise at worst case transitions and
temperatures. (3) Adjustable to zero with external potentiometer as shown in Figure 4b. (4) Full scale error is the worst case of Full Scale untrimmed deviation from
ideal last code transition divided by the transition voltage and includes the effect of offset error. (5) All specifications in dB are referred to a full-scale input. (6) Full-
Power 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 overvoltage.

ORDERING INFORMATION
ELECTROSTATIC
DISCHARGE SENSITIVITY
Electrostatic discharge can cause damage ranging from per-
formance degradation to complete device failure. Burr-
Brown Corporation recommends that all integrated circuits
be handled and stored using appropriate ESD protection
methods.
ESD damage can range from subtle performance degrada-
tion to complete device failure. Precision integrated circuits
may be more susceptible to damage because very small
parametric changes could cause the device not to meet
published specifications.
