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

NOTES: (1) LSB means Least Significant Bit. One LSB for the
±
10V input range is 4.88mV. (2) Typical rms noise at worst case transition. (3) As measured with
fixed resistors shown in Figure 7b. 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)
This is the time delay after the ADS7806 is brought out of Power Down Mode until all internal settling occurs and the analog input is acquired to rated accuracy.
A Convert Command after this delay will yield accurate results. (6) All specifications in dB are referred to a full-scale input. (7) Usable Bandwidth defined as Full-
Scale input frequency at which Signal-to-(Noise + Distortion) degrades to 60dB. (8) Recovers to specified performance after 2 x FS input overvoltage.
