ADI launches differential amplifier for high speed data converters
Analog Devices has introduced a new differential rf/if amplifier for driving high speed, 12 to 18bit a/d converters.
The ADL5565 is optimised for wide bandwidth, low distortion and low noise. It is targeted at applications in which high linearity and low noise are critical, including IF sampling receivers in wireless infrastructure applications, industrial instrumentation and defence electronics.
The differential amplifier features 3dB bandwidth of 5GHz and achieves distortion, noise and IP3/IP2 performance of 300MHz. ADI claims it delivers the industry's best HD3 and OIP3 distortion levels (–103dB and 51dBm at 100 MHz; –95dB and 47dBm at 200MHz).
The device is pin programmable using internal gain resistors, which allows for fixed gains of 6, 12 or 15.5dB. It has two external input resistors, which allows any gain between 0 and 15.5dB to be realised. Output noise level is rated at 5.5nV/rt-Hz, while nominal operating power supply is said to be 3.3V.
