1. CHARACTERISTICS AND SPECIFICATIONS

•

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

•

•

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

µV.

4.

Scales with MCLK.
