Agilent HCPL-7860/HCPL-786J

Optically Isolated

Sigma-Delta (Σ−∆) Modulator

Data Sheet

In operation, the HCPL-7860/

HCPL-786J Isolated Modulator

Features

• 12-bit Linearity

(optocoupler with 3750 V

RMS

• 200 ns Conversion Time (Pre-

dielectric withstand voltage

rating) converts a low-

Trigger Mode 2 with HCPL-0872)

bandwidth 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.

• 12-bit Effective Resolution with 5

µs Signal Delay (14-bit with 102

µs) (with HCPL-0872)

Description

• Fast 3 µs Over-Range Detection

(with HCPL-0872)

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.

•

200 mꢀ Input Range with Single

5 ꢀ Supply

• 1% Internal Reference ꢀoltage

Matching

• Offset Calibration (with HCPL-

0872)

• -40°C to +85°C Operating

Temperature Range

• 15 kꢀ/µs Isolation Transient

Immunity

• Safety Approval: UL 1577, CSA
