Agilent HCPL-7860/HCPL-786J

Optically Isolated Sigma-Delta (Σ−∆) Modulator

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 (optocoupler with 3750 VRMS dielectric withstand voltage rating) converts a lowbandwidth analog input into a high-speed 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. The modulator data and on-chip sampling clock are encoded and transmitted across the isolation boundary where they are recovered and decoded into separate high-speed clock and data channels.

Features

• 12-bit Linearity

• 200 ns Conversion Time (PreTrigger 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 Transient Immunity

• Safety Approval: UL 1577, CSA and IEC/EN/DIN EN 60747-5-2

Applications

• Motor Phase and Rail Current Sensing

• Data Acquisition Systems

• Industrial Process Control

• Inverter Current Sensing

• General Purpose Current Sensing and Monitoring
