AD8145 is a high-speed differential receiver with comparator function from Analog Devices. It has a speed of 500 MHz, 2000 V/μs of fast response, 0.1 dB of flatness, 69 dB of CMRR, 1MΩ input impedance, ±3.5V input voltage range, 15 ns of fast settling time, 13nV/√Hz of input noise, and a small 32-lead package. It is suitable for RGB video receivers, YPbPr video receivers, keyboard, video, mouse (KVM) receivers, unshielded twisted pair (UTP) receivers, automotive driver assistance (AD8145W) and automotive infotainment (AD8145W) applications.
The AD8145 is a high‑speed, triple differential receiver designed for RGB video and other analog signal applications. It converts three differential inputs to single‑ended outputs and includes two auxiliary comparators for sync‑pulse extraction or general‑purpose comparison.
The document provides detailed specifications such as 500 MHz 3‑dB bandwidth, 2100 V/µs slew rate, 13 nV/√Hz input noise, and 69 dB CMRR at 10 MHz, as well as pin‑out tables, thermal data, absolute maximum ratings, and automotive‑grade (AD8145W) information.
| Slew Rate (Vout = 2 V p‑p) | 2100 V/µs |
|---|---|
| Input Voltage Noise (f > 10 kHz) | 13 nV/√Hz |
| Common‑Mode Rejection (Vem = 1 V p‑p, f = 10 MHz) | 69 dB |
| Power‑Supply Operating Range | 4.5 V to 11 V |
The gain can be set to 1 or 2 by connecting each channel’s GAIN_x pin to its output for gain 1, or to a reference voltage (normally ground) for gain 2.
The AD8145W is the automotive‑grade version, qualified per AEC‑Q100 for use in automotive applications.
The maximum supply voltage rating is 12 V.
The exposed underside pad must be connected to ground and thermally coupled to a PCB copper plane to achieve the specified thermal resistance.
