HCPL7860 - Optically Isolated Sigma-Delta (S-D) Modulator

Download the HCPL7860 datasheet PDF. This datasheet also covers the HCPL-7860 variant, as both devices belong to the same optically isolated sigma-delta (s-d) modulator family and are provided as variant models within a single manufacturer datasheet.

Description

The HCPL-7860/HCPL-786J Optically Isolated Modulator and HCPL-0872 Digital Interface IC or digital filter together form an isolated programmable two-chip analog-to-digital converter.

The isolated modulator allows direct measurement of motor phase currents in power inverters.

Features

  • 12-bit Linearity.
  • 200 ns Conversion Time (Pre-Trigger Mode 2 with HCPL-0872).
  • 12-bit Effective Resolution with 5 µs Signal Delay (14-bit with 102 µs) (with HCPL-0872).
  • Fast 3 µs Over-Range Detection (with HCPL-0872).
  • ± 200 mV Input Range with Single 5 V Supply.
  • 1% Internal Reference Voltage Matching.
  • Offset Calibration (with HCPL-0872).
  • -40°C to +85°C Operating Temperature Range.
  • 15 kV/µs Isolation Transie.

HCPL-7860/HCPL-786J Optically Isolated Sigma-Delta (S-D) Modulator Data Sheet Lead (Pb) Free RoHS 6 fully compliant RoHS 6 fully compliant options available; -xxxE denotes a lead-free product Description The HCPL-7860/HCPL-786J Optically Isolated Modulator and HCPL-0872 Digital Interface IC or digital filter together form an isolated programmable two-chip analog-to-digital converter. The isolated modulator allows direct measurement of motor phase currents in power inverters. In operation, the HCPL-7860/HCPL-786J Isolated Modulator converts a low-bandwidth analog input into a highspeed one-bit data stream by means of a Sigma-Delta (Σ−∆) over-sampling modulator. This modulation provides for high noise margins and excellent immunity against isolation-mode transients.
