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 = 25°C.

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

ANALOG CHARACTERISTICS T = -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, unless other-

wise stated; BUFEN = V1+ unless otherwise stated. Connected per Figure 6. Bipolar mode unless otherwise

stated.

1. No missing codes is guaranteed at 16 bits resolution over the specified temperature range.

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

3. One LSB is equivalent to VREF ÷ 2¹⁶or 4.096 ÷ 65536 = 62.5 µV.

4. Scales with MCLK.
