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 6. Bipolar mode unless otherwise stated.

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

2. One LSB is equivalent to (2 x VREF) ÷ 224 or (2 x 4.096) ÷ 16,777,216 = 488 nV.

3. Scales with MCLK.
