ADC1205/ADC1225 12-Bit Plus Sign
m
P Compatible A/D Converters
General Description
The ADC1205 and ADC1225 are CMOS, 12-bit plus sign
successive approximation A/D converters. The 24-pin
ADC1205 outputs the 13-bit data result in two 8-bit bytes,
formatted high-byte first with sign extended. The 28-pin
ADC1225 outputs a 13-bit word in parallel for direct inter-
face to a 16-bit data bus.
Negative numbers are represented in 2’s complement data
format. All digital signals are fully TTL and MOS compatible.
A unipolar input (0V to 5V) can be accommodated with a
single 5V supply, while a bipolar input (
b
5V to
a
5V) re-
quires the addition of a 5V negative supply.
The ADC1205C and ADC1225C have a maximum non-lin-
earity of 0.0224% of Full Scale.
