The LTC
®
1292/LTC1297 are data acquisition systems that
contain a 12-bit, switched-capacitor successive approxi-
mation A/D, a differential input, sample-and-hold on the
(+) input, and serial I/O. When the LTC1297 is idle between
conversions it automatically powers down reducing the
supply current to 5µA, typically. The LTC1292 is capable
of digitizing signals at a 60kHz rate and with the device’s
excellent AC characteristics, it can be used for DSP appli-
cations. All these features are packaged in an 8-pin DIP
and are made possible using LTCMOS
TM
switched-capaci-
tor technology.
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 wires.
Because of their accuracy, ease of use and small package
size these devices are well suited for digitizing analog
signals in remote applications where minimum number of
interconnects and power consumption are important.

How can I expand external large-capacity SRAM via EMI interface of STR912?
I looked at the data sheet: 8-bit non-multiplexed mode has only 16-bit address, which means it can only expand 64KB. And 16-bit data/address multiplexing mode has 24-bit address, which means it can ex...
