AD8145 is a high speed triple differential receiver with comparator functions from Analog Devices.
The AD8145 is a high‑speed, triple differential receiver designed for RGB video, KVM, and UTP applications. It offers up to 500 MHz bandwidth, low input‑referred noise, and configurable gain of 1 or 2. The device includes two auxiliary comparators for video sync decoding or general‑purpose comparison.
Key specifications include a –3 dB bandwidth of 500 MHz (2 V p‑p output), input voltage noise of 13 nV/√Hz above 10 kHz, and operation over a temperature range of –40 °C to +105 °C. The part is supplied in a 32‑lead 5 mm × 5 mm LFCSP package with a maximum supply voltage of 12 V and typical quiescent current of 48.5 mA on the positive supply.
