ANALOG DEVICES ADA4960-1ACPZ-R2 Operational Amplifier, Low Distortion, 1 Channels, 5 GHz, 8700 V/µs, 4.75V to 5.25V, LFCSP, 16 Pins

ADA4960-1ACPZ-R2 is a high-performance, differential amplifier optimized for RF and IF applications. It achieves better than 63dB IMD3 performance for frequencies up to and beyond 1GHz, making it an ideal driver for 8-bit to 10-bit giga-sample analogue-to-digital converters (ADCs). The buffered inputs of the ADA4960-1 isolate the gain-setting resistor (RG) from the signal inputs, maintaining a constant 10Kohm input resistance, easing matching and input drive requirements. The ADA4960-1 has a nominal 150 ohm differential output impedance. The ADA4960-1 is optimized for wideband, low-distortion performance for frequencies up to and beyond 1GHz. It is used in applications such as differential ADC drivers for giga-sample ADCs GBPS line drivers with pre-emphasis, high-speed data acquisition, electronic surveillance countermeasures, pulse capture and conditioning, oscilloscopes, satellite communications, single-ended-to-differential converters, RF/IF gain blocks.
