grounded should be connected directly to a single-
point ground through a separate, low-resistance (less
than 0.2Ω) connection. The current at OUT and AGND
varies with input code, creating a code-dependent
error if these terminals are connected to ground (or vir-
tual ground) through a resistive path.
Parasitic coupling of the signal from REF to OUT is an
error source in dynamic applications. This coupling is
normally a function of board layout and pin-to-pin pack-
age capacitance. Minimize digital feedthrough with
guard traces between digital inputs, REF, and OUT
pins.
The MAX551/MAX552 have high-impedance digital
inputs. To minimize noise pick-up, tie them to either

tice, connect active inputs to V
value resistors (1MΩ) to prevent static charge accumu-
lation if the pins are left floating, such as when a circuit
card is left unconnected.
The CLR input on the µMAX device has an internal pull-
up resistor with a typical value of 125kΩ. If the CLR
input is not used, tie it to V
rent.
