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 = 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.

One LSB is equivalent to (2 x VREF) ÷ 2

24

or (2 x 4.096) ÷ 16,777,216 = 488 nV.

3.

Scales with MCLK.

4.

Measured using an input signal of 1 V DC.
