描述The VECANA01 consists of three 12-bit analog-to-digital converters preceded by five simultaneously operating sample-hold amplifiers, and multiplexers 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.特性10 FULLY DIFFERENTIAL INPUTS 5 SIMULTANEOUS SAMPLED CHANNELS PLUS 2 SYNCHRONIZED SAMPLING CHANNELS 3 SYNCHRONIZED 12-BIT ADCs 12.8us THROUGHPUT RATE DIGITALLY SELECTABLE INPUT RANGES ±5V POWER SUPPLIES SERIAL DIGITAL INPUT/OUTPUTS 7 SIGN AND 3 DIGITALLY PROGRAMMABLE WINDOW COMPARATOR APPLICATIONS AC MOTOR SPEED CONTROLS THREE PHASE POWER CONTROL UNINTERRUPTABLE POWER SUPPLIES VIBRATION ANALYSIS
