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 measured 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. DITHER = VL
unless otherwise stated; BUFEN = V1+ unless otherwise stated. Connected per Figure 5. Bipolar mode unless oth-
erwise stated.

1. Applies after calibration at any temperature within -40 °C to +85 °C.
2. No missing codes is guaranteed at 16 bits resolution over the specified temperature range.
3. Total drift over specified temperature range after calibration at power-up, at 25º C.
4. With DITHER off the output will be dominated by quantization.
5. Scales with MCLK.
