CS5501 ANALOG CHARACTERISTICS
VA-, VD- = -5V; VREF = 2.5V; CLKIN = 4.096MHz; Bipolar Mode; MODE = +5V; R
to AGND at AIN (see Note 1); Digital Inputs: Logic 0 = GND; Logic 1 = VD+; unless otherwise specified.)
Notes: 1. The AIN pin presents a very high input resistance at dc and a minor dynamic load which scales to the

master clock frequency. Both source resistance and shunt capacitance are therefore critical in
determining the CS5501’s source impedance requirements. For more information refer the text section
This is guaranteed by design and /or characterization. Recalibration at any temperature will remove
these errors.
