Broadcom Inc. Hermetically Sealed Analog Isolation Amplifier 5962-9755701HPC

The 5962-9755701HPC is a high reliability DSCC SMD Class H isolation amplifier that provides accurate, electrically isolated and amplified representations of voltage and current. When used with a shunt resistor to monitor the motor phase current in a high speed motor drive, the device will offer superior reliability compared with the traditional solutions such as current transformers and Hall-effect sensors. This device consists of a sigma-delta analog-to-digital converter optically coupled to a digital-to-analog converter in a hermetically sealed 8-Pin ceramic DIP package with gold plated leads. Solder dipped leads and various lead form options are also available. See the datasheet for details. The products are capable of operation and storage over the full military temperature range and may also be purchased as commercial grade. The 5962-9755701HPC is manufactured and tested on a MIL-PRF-38534 cerified line and included in the DSCC Qualified Manufacturers List, QML-38534 for Hybrid Microcircuits. Superior performance in design critical specifications such as common-mode rejection, offset voltage, nonlinearity, and operating temperature make this product an excellent choice for designing reliable products such as motor controllers and inverters. Common-mode rejection of 8 kV/micro-second makes the HCPL-7850/7851 suitable for noisy electrical environments such as those generated by the high switching rates of power IGBTs. Low offset voltage together with a low offset voltage temperature coefficient permits accurate use of auto-calibration techniques. Gain tolerance of 5% with 0.1% nonlinearity further provide the performance necessary for accurate feedback and control.
