1. CHARACTERISTICS AND SPECIFICATIONS

ANALOG CHARACTERISTICS

(VA+, VD+ = 5 V ±5%; VREF+ = 5 V; VA-, VREF-, DGND = 0 V; MCLK = 4.9152 MHz;

OWR (Output Word Rate) = 60 Sps; Bipolar Mode; Gain = 32)

(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. LSB is 24 bits.

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

thermocouples. The PGIA contributes 5 nV of offset drift, and the modulator contributes 640/G nV of

offset drift, where G is the amplifier gain setting.

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