✻ Specifications same as grade to the left.

NOTES: (1) With minimum VCC /VSS requirements, internal reference enabled.

(2) Please refer to the “Theory of Operation” section for more information with respect to output voltage configurations.

(3) See Figure 7 for gain and offset adjustment connection diagrams when using the internal reference.

(4) The minimum value for REFIN must be equal to the greater of VSS +14V and +4.75V, where +4.75V is the minimum voltage allowed.

(5) Reference low-pass filter values: 100k

Ω, 1.0µF (See Figure 10).

ELECTRICAL CHARACTERISTICS

All specifications at TA = TMIN to TMAX, VCC = +15V, VSS = –15V, VDD = +5V, internal reference enabled, unless otherwise noted.
