Application Notes
- Partial Discharge Testing: What It Is and What It MeansPDF, 24 Kb, File published: Sep 27, 2000
What follows is information about the older test method and what it accomplished, partial discharge, how we test for it, and a comparison of similar products tested using the different methods. Some of this material appears in the ISO120/121 PDS, but bear repeating to give you the whole story. - Synchronization Of ISO120/121 Isolation AmplifierPDF, 29 Kb, File published: Sep 27, 2000
Internal clock circuitry in the ISO120/121 precision isolation amplifier (ISO amp) can be synchronized to an external clock signal. Synchronization to an external clock can be used to eliminate beat frequencies in multichannel systems or for rejection of specific AC signals and their harmonics. - Boost ISO120 Bandwidth to More Than 100kHzPDF, 55 Kb, File published: 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 Operation of Isolation AmplifiersPDF, 46 Kb, File published: 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 - Isolated RS-485 Reference DesignPDF, 80 Kb, File published: 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.
