CHARACTERISTICS & SPECIFICATIONS

ANALOG CHARACTERISTICS (T

= 25 °C; VA± = ±2.5 V ±5%, VD+ = 5 V ±5%, VREF+ = 2.5 V,

VREF- = 0.0 V, F

CLK

= 32.768 kHz, OWR (Output Word Rate) = 15 Sps, Bipolar Mode, Input Range = ±2.5 V.)

(See Notes 1 and 2.)

Notes: 1. Applies after system calibration at any temperature within -40 °C ~ +85 °C.

2. Specifications guaranteed by design, characterization, and/or test.

3. Specification applies to the device only and does not include any effects by external parasitic

thermocouples.

4. Drift over specified temperature range after calibration at power-up at 25 °C.

5. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25 °C.

6. For peak-to-peak noise multiply by 6.6 for all ranges and output rates.

Specifications are subject to change without notice.
