Optically Isolated Sigma-Delta Modulator

www.DataSheet4U.com Agilent HCPL-7560 Σ∆ 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 µ 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./ ENCODE 7 DECODE 6 Applications • Motor Phase and Rail Current Sensing • Data Acquisition Systems • Industrial Process Control • Inverter Current Sensing • General Purpose Current Sensing and Monitoring 4 5 HCPL-7560 - A 0.1 µF bypass capacitor must be connected between pins VDD and Ground CAUTION: It is advised that normal static precautions be taken in handling and assembly of this component to prevent damage and/or degradation, which may be induced by ESD.
