DS202F5

NBV = -2.1 V, FCLK = 32.768 kHz, OWR (Output Word Rate) = 15 Sps, Bipolar Mode, Input Range = ±100 mV;

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

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

5. See the section of the data sheet which discusses input models on page 15.

Notes: 6. Wideband noise aliased into the baseband. Referred to the input. Typical values shown for 25 °C.

7. For Peak-to-Peak Noise multiply by 6.6 for all ranges and output rates.

8. For input ranges <100 mV and output word rates >60 Sps, 32.768 kHz chopping frequency is used.

Specifications are subject to change without notice.
