1. CHARACTERISTICS AND SPECIFICATIONS

•

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

•

•

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

±5%; VL -VLR = 3.3 V, ±5%; VREF = (VREF+) - (VREF-) = 4.096V; MCLK = 8 MHz; SMODE = VL. BUFEN = V1+

unless otherwise stated. Connected per Figure 8. Bipolar mode unless otherwise stated.

1.

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

2.

3.

Scales with MCLK.

4.

Measured using an input signal of 1 V DC.
