ELECTROSTATIC
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.

NOTES: (1) LSB means Least Significant Bit. For the 12-bit,
±
10V input ADS7804, one LSB is 4.88mV. (2) Typical rms noise at worst case transitions and
temperatures. (3) As measured with fixed resistors shown in Figure 4. 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
±
10V 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.
