HCPL2630M

HCPL-2630M is an optically isolated amplifier (isolation amplifier) from Avago/Broadcom. It provides galvanic isolation between input and output, letting you sense or transfer an analog signal across a barrier without a direct electrical connection.
How it works: the input side uses an LED; the light is detected on the output side by a photoreceiver and an on‑chip amplifier, producing an output voltage proportional to the input with a fixed gain. The device requires separate supply rails on each side (Vcc1 for input, Vcc2 for output) to maintain isolation.
Typical strengths: robust isolation ratings, good common‑mode transient immunity, wide bandwidth for an isolation amplifier, and good linearity/accuracy for analog sensing and control loops.
Common applications: isolated data acquisition, motor‑control feedback, power‑electronics sensing, and instrumentation requiring galvanic isolation.
Note: check the datasheet for exact isolation voltage, gain, bandwidth, input/output ranges, and package variant details for HCPL-2630M.

Concise features of HCPL2630M:
- High-speed optically isolated digital optocoupler (logic-gate output)
- TTL/CMOS-compatible input and output
- Isolation voltage: typically 2.5 kV RMS between input and output
- Data rate in the tens of Mbps range (high-speed logic isolation)
- Low input LED drive current (low-power input)
- Outputs capable of sourcing/sinking a few milliamps (totem-pole)
- Wide operating temperature range (typical -40°C to +125°C)
- Available in compact packages (DIP8/SOIC/MSE variants)
Note: Always check the latest datasheet for exact electrical specs and packaging variants.

HCPL2630M comes in an 8-pin molded DIP (DIP-8) package (through-hole).

- Pin count: 8 pins (8-pin package).
- Function: Dual high‑speed optocoupler. It provides two isolated channels: each channel has an input LED (two LEDs total) and an isolated output transistor (open-collector) on the output side, powered by a common Vcc2 and GND2. Outputs require pull-up resistors to Vcc. The M suffix indicates the RoHS/Pb‑free version.

- Manufacturer: Broadcom Inc. (the HCPL2630M lineage comes from Avago Technologies, now part of Broadcom)
- What kind of company: Global semiconductor company that designs and manufactures a wide range of integrated circuits and related products.

Applications of HCPL-2630M include:
- High-speed galvanic isolation for digital signals between hosts (MCUs/DSPs/FPGA) and noisy environments
- Isolated I/O and data links in industrial automation and PLCs
- Automotive and medical equipment requiring safety-critical isolation
- Control/sensing interfaces in power electronics (SMPS, inverters, motor drives)
- Isolated sensor interfaces for measurement and instrumentation
- Isolated communications interfaces for data buses in harsh environments
