ADN4650BRWZ-RL7

ANALOG DEVICES  ADN4650BRWZ-RL7  Digital Isolator, 5KV, 2 Channel, 4 ns, 3 V, 3.6 V, WSOIC, 20 Pins 新

Product Details

The ADN4650 is a signal isolated, low voltage differential signaling LVDS buffers that operate at up to 600 Mbps with very low jitter.

The devices integrate Analog Devices, Inc., iCoupler® technology, enhanced for high speed operation, to provide galvanic isolation of the TIA/EIA-644-A compliant LVDS drivers and receivers. This technology allows drop-in isolation of an LVDS signal chain.

For high speed operation with low jitter, the LVDS and isolator circuits rely on a 2.5 V supply. An integrated on-chip low dropout regulator LDO can provide the required 2.5 V from an external 3.3 V power supply. The devices are fully specified over a wide industrial temperature range and are available in a 20-lead, wide body SOIC package with 5 kV rms isolation or a 20-lead SSOP package with 3.75 kV rms isolation.
