Description

The HCPL-7840 isolation amplifier provides accurate, electrically isolated and amplified representations of voltage and current.

When used with a shunt resistor in the current path, the HCPL-7840 offers superior reliability, cost effectiveness, size and autoinsertability compared withthe traditional solutions such as current transformers and Halleffect sensors.

The HCPL-7840 consists of a sigma-delta analog-to-digital onverter optically coupled to a digital-to-analog converter. Superior performance in design criticalspecifications such as common-mode rejection, offset voltage, nonlinearity, operating temperature range and regulatory compliance make the HCPL7840 the clear choice for designing reliable, lower-cost, reduced-size products such as motor controllers and inverters.

Common-mode rejection of 15 kV/ms makes the HCPL-7840 uitable 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.A wide operating temperature range with specified performance allows the HCPL-7840 to be used in hostile industrial environments.
