GENERAL DESCRIPTION
The XRD87L94 is a 1 MSPS 12-bit subranging
Analog-to-Digital Converter with DNL = +1 LSB and INL = +2.5
LSB. The XRD87L94 contains an internal track and hold and an
analog input bandwidth of 10 MHz.
The XRD87L94 operates with a single 3.3 V supply while
consuming 30 mW of power (typical). Separate pins for
reference ladder terminals and power supplies allow flexibility
for various A
IN
, V
REF
, and power supply ranges.
Data is presented at the parallel output port every clock cycle
after a 2.5 cycle pipeline delay from sample edge. The digital
output port is also equipped with a 3-state function. MINV
enables binary and 2’s complement data formatting. Through
