LTC1291
1291fa
The LTC
1291 is a data acquisition system that contains
a serial I/O successive approximation A/D converter. It
uses LTCMOS
TM switched capacitor technology to per-
form a 12-bit unipolar A/D conversion. The input multi-
plexer can be configured for either single-ended or differ-
ential inputs. An on-chip sample-and-hold is included on
the “+” input. When the LTC1291 is idle, it can be powered
down in applications where low power consumption is
desired. An external reference is not required because the
LTC1291 takes its reference from the power supply (VCC).
All these features are packaged in an 8-pin DIP.
The serial I/O is designed to communicate without external
hardware to most MPU serial ports and all MPU parallel
I/O ports allowing data to be transmitted over three or four
wires. Given the accuracy, ease of use and small package
size, this device is well suited for digitizing analog signals
in remote applications where minimum number of inter-
connects, small physical size, and low power consump-
tion are important.
