10-Bit μP Compatible A/D Converter
General Description
NOTE: This device is obsolete. This data sheet is provid-
ed for information only.
The ADC1005 is a CMOS 10-bit successive approximation A/
D converter. The 20-pin ADC1005 outputs 10-bit data in a
two-byte format for interface with 8-bit microprocessors.
The ADC1005 has differential inputs to permit rejection of
common-mode signals, allow the analog input range to be
offset, and also to permit the conversion of signals not re-
ferred to ground. In addition, the reference voltage can be
adjusted, allowing smaller voltage spans to be measured with
10-bit resolution.
