Description
Eight digital outputs. D1 (MSB) is the most
significant bit of the digital output word;
D8 (LSB) is the least significant bit.
One of two analog ground returns. Both
grounds should be connected together and to
low impedance ground plane near the AD9048.

Positive supply terminals; nominally +5.0 V.
Negative supply terminals; nominally –5.2 V.
Input for conversion signal; sample of analog
input signal taken on rising edge of this pulse.

Description
Most negative reference voltage for internal
reference ladder.
Midpoint tap on internal reference ladder.
Most positive reference voltage for internal
reference ladder.
Analog input signal pin.
“Not Most Significant Bit Invert.” In normal
operation, this pin floats high; logic LOW at
NMINV inverts most significant bit of digital
output word [D1 (MSB)].
“Not Least Significant Bit Invert.” In normal
operation, this pin floats high; logic LOW at
NLINV inverts the seven least significant bits
of the digital output word.
