10-Channel 12-Bit Data Acquisition System
The VECANA01 consists of three 12-bit Analog-to-digital converters preceded by five simultaneously operating sample-hold Amplifiers and multi 6855 plexers for 10 differential inputs. The ADCs have simultaneous serial outputs for high speed data transfer and data processing.
The VECANA01 also offers a Programmable Gain Amplifier with programmable gains of 1.0V/V, 1.25V/V, 2.5V/V, and 5.0V/V. Channel selection and gain selection are selectable through the serial input control word. The high through put rate is maintained by simultaneously clocking in the 13-bit input control word for the next conversion while the present conversions are clocked out.
The part also contains an 8-bit digital-to-analog converter whose digital input is supplied as part of the input control word.
