com Agilent HCPL-7560 Optically Isolated Sigma-Delta (Σ-∆) Modulator Data Sheet Features • 8-bit Linearity Description The HCPL-7560 Optically Isolated Modulator and HCPL0872 Digital Interface IC or digital filter together form an isolated programmable twochip analog-to-digital converter.
The isolated modulator allows direct measurement of motor phase currents in power inverters.
In operation, the HCPL-7560 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.
• 200 ns Conversion Time (PreTrigger Mode 2 with HCPL-0872) • 8-bit Effective Resolution with 5 ìs 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 • 5% Internal Reference Voltage Matching • Offset Calibration (with HCPL0872) • -40°C to +85°C Operating Temperature Range • 15 kV/µs Isolation Transient Immunity 1 8 • Safety Approval: UL 1577, CSA and IEC/EN/DIN EN 60747-5-2 HCPL-0872 or Digital Filter MCU or DSP 2 Input Curr ent 3 SIGMADELTA MOD.
