12-Bit, 50kHz, Complete
Data Acquisition Systems
GENERAL DESCRIPTION
Using thin and thick-film hybrid technology, Murata Power Solutions offers
complete low-cost data acquisition systems with superior performance and
reliability.
The HDAS-8 (with 8 differential input channels) and the HDAS-16 (with
16 single-ended input channels) are complete, high-performance, 12-bit data
acquisition systems in 62-pin packages. Each HDAS may be expanded up to
32 single-ended or 16 differential channels by adding externalmultiplexers.
Internal channel address sequencing is automatic after each conversion,
or the user may supply external channel addresses.
Internal HDAS circuitry includes:
Analog input multiplexer (16 S.E. or 8 diff.)
Resistor-programmable instrumentation amplifier
Sample-and-hold circuit complete with MOS hold capacitor
10 Volt buffered reference
12-bit A/D converter with three-state outputs and control logic
