ADC1005 General Description
The ADC1005 is a CMOS 10-bit successive approximation A/D converter. The 20-pinADC1005 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.
