1. CHARACTERISTICS AND SPECIFICATIONS

• Min / Max characteristics and specifications are guaranteed over the specified operating conditions.

• Typical characteristics and specifications are measured at nominal supply voltages and TA = 25°C.

• VLR = 0 V. All voltages with respect to 0 V.

ANALOG CHARACTERISTICS TA = -40 to +85 °C; V1+ = V2+ = +2.5 V, ±5%; V1- = V2- = -2.5 V,

±5%; VL -VLR = 3.3 V, ±5%; VREF = (VREF+) - (VREF-) = 4.096V; MCLK = 16 MHz; SMODE = VL.

BUFEN = V1+ unless otherwise stated. Connected per Figure 7. Bipolar mode unless otherwise stated.

1. Applies after calibration at any temperature within -40 °C to +85 °C.

2. No missing codes is guaranteed at 24 bits resolution over the specified temperature range.

3. Total drift over specified temperature range after calibration at power-up, at 25º C.

4. Scales with MCLK.
