CS5566
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.
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
Bipolar mode unless otherwise stated.

No missing codes is guaranteed at 24 bits resolution over the specified temperature range.
One LSB is equivalent to (2 x VREF) ÷ 2
24
or (2 x 4.096) ÷ 16,777,216 = 488 nV.
Scales with MCLK.
Measured using an input signal of 1 V DC.
