应用须知
- Boost ISO120 Bandwidth to More Than 100kHzPDF, 55 Kb, 档案已发布: Sep 27, 2000
There has been considerable demand for high-bandwidth isolation amplifiers. The highest bandwidth Burr-Brown ISO amps are the ISO100 and the ISO120/121/122 family with bandwidths of about 50kHz. The ISO120/121 bandwidth can be boosted to more than 100kHz by adding gain in the feedback. - Single Supply 4-20mA Current Loop ReceiverPDF, 29 Kb, 档案已发布: Sep 27, 2000
Many industrial current-loop data acquisition systems operate on a 24V or 28V single supply. You can make a single-supply current loop receiver with the RCV420 by using its 10V reference as a pseudo ground. The RCV420 will convert a 4-20mA loop current into a 0 to 5V output voltage with no external components required. The current loop can be sourcing or sinking and can be referenced to either the - Single-Supply Operation of Isolation AmplifiersPDF, 46 Kb, 档案已发布: Sep 27, 2000
For simplicity, many systems are designed to operate from a single external power supply. In battery powered systems such as aircraft and automotive, it's often a requirement. Isolation amplifiers such as the ISO120 and ISO122 can be easily modified for input side single-supply operation with the addition of an INA105 difference amplifier. With ISO amps, it's the isolated input side power supply w - IC Building Blocks Form Complete Isolated 4-20mA Current-LoopPDF, 72 Kb, 档案已发布: Sep 27, 2000
Current loops have become the standard for signal transmission in the process control industry. Current loops are insensitive to noise and are immune to errors from line impedance. Adding isolation to the 4-20mA current loop protects system electronics from electrical noise and transients. It also allows transducers to be electrically separated by hundreds of volts. - Simple Output Filter Eliminates ISO Amp Output Ripple And Keeps Full BandwidthPDF, 186 Kb, 档案已发布: Sep 27, 2000
The ISO120/121/122 isolation amplifiers (ISO amps) have a small (10-20mVp-p typ) residual demodulator ripple at the output. A simple filter can be added to eliminate the output ripple without decreasing the 50kHz signal bandwidth of the ISO amp. - Noise Sources In Applications Using Capacitive Coupled Isolated AmplifierPDF, 101 Kb, 档案已发布: Sep 27, 2000
Noise is a typical problem confronting many isolation applications. Isolation products such as analog isolation amplifiers, optocouplers, transformers and digital couplers, are used in applications to transmit signals across a high voltage barrier while providing galvanic separation between two grounds. - Isolated RS-485 Reference DesignPDF, 80 Kb, 档案已发布: Oct 28, 2009
This design note presents the reference designs of isolated RS-485 nodes, using bus voltages of 3.3 V and 5 V. Various transceivers are used to satisfy the requirements for low, medium, and high data rates, as well as to accommodate the need for half- and full-duplex operation.
