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 T
A
= 25°C.
• VLR = 0 V. All voltages with respect to 0 V.
ANALOG CHARACTERISTICS
T
A
= -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) ÷ 2
24
or (2 x 4.096) ÷ 16,777,216 = 488 nV.
3. Scales with MCLK.
