AD8045ACPZ-REEL GENERAL DESCRIPTION

The AD8045 is a unity-gain stable voltage feedback amplifierwith ultralow distortion, low noise, and high slew rate. With aspurious-free dynamic range of −90 dBc at 20 MHz, the AD8045 isan ideal solution in a variety of applications, including ultrasound,automated test equipment (ATE), active filters, and analog-to-digital converter (ADC) drivers. The Analog Devices, Inc.,proprietary next generation XFCB process and innovativearchitecture enable such high performance amplifiers.The AD8045 features a low distortion pinout for the LFCSP,which improves second harmonic distortion and simplifies thelayout of the circuit board.The AD8045 has a 1 GHz bandwidth, a 1350 V/µs slew rate, andsettles to 0.1% in 7.5 ns. With a wide supply voltage range (3.3 Vto 12 V) and a low offset voltage (200 µV), the AD8045 is anideal candidate for systems that require high dynamic range,precision, and high speed.The AD8045 amplifier is available in a 3 mm × 3 mm LFCSPand the standard 8-lead SOIC. Both packages feature an exposedpaddle that provides a low thermal resistance path to theprinted circuit board (PCB). This enables more efficient heattransfer and increases reliability. The AD8045 works over theextended industrial temperature range (−40°C to +125°C).04814-0-079FREQUENCY (MHz)1000.1110HARMONIC DISTORTION (dBc)–20–30–40–50–60–70–80–90–100–120–110HD3 LFCSPHD2 LFCSPG = +1VS = ±5VVOUT = 2V p-pRL = 1kΩRS = 100ΩFigure 3.
