5-GHz differential amplifier from ADI to drive ADC signals

Analog Devices has introduced the 5-GHz differential amplifier able to drive ADC (analog-to-digital converter) signals from DC to 1 GHz. ADI says the ADA4960-1 differential amplifier is a high-performance, low-distortion, ultra-high-speed differential amplifier effective for a wide variety of high-speed ADCs with 10-bit linearity to 500 MHz and 8-bit linearity up to 1 GHz. This amplifier can drive ADCs such as AD9626 12-bit ADC and the AD9211 10-bit ADC.

The ADA4960-1 differential amplifier (data sheet) consumes just 60 mA of quiescent current when operating up to 1 GHz. The amplifier features a 8,700 V/µs (volts per microsecond) slew rate (AV = 6 dB, 2-V step) and wideband, low-distortion performance for frequencies up to and beyond 1 GHz. It is therefore suggested for RF (radio frequency) and IF (immediate frequency) wired communications applications in industrial and instrumentation, defense electronics and aerospace designs. ADI says the ADA4960-1 is suitable for line driver and channel equalization applications.

Other key features of ADA4960-1 are:

--Single resistor programmable gain: 0 dB to 18 dB

--Low harmonic distortion (HD2/HD3 @ AV = 6 dB)
-88/-69 dBc @ 250 MHz
-77/-66 dBc @ 500 MHz
-73/-72 dBc @ 1 GHz
-63 dBc IMD3 @ 1 GHz

--Fast settling time of 1 ns to 1% and overdrive recovery of 10 ns.
