GENERAL DESCRIPTION

The ADA4960-1 is a high performance differential amplifier

optimized for RF and IF applications. It achieves better than

63dB SFDR performance at frequencies up to 500 MHz, and

52dB up to 1GHz, making it an ideal driver for high speed 8-bit

to 10-bit giga-sample analog-to-digital converters (ADCs).

The device also includes a unity gain buffer, for the buffering of

DC signals such as the common-mode-input to the amplifier.

This buffer is found between pins 6 (input) and pin5 (output).

If this buffer is not used, the output can be left disconnected

and the input can be grounded.

Unlike other wideband differential amplifiers, the ADA4960-1

has buffered inputs that isolate the gain-setting resistor (RG)

from the signal inputs. As a result, the ADA4960-1 maintains a

constant 10 kΩ differential input resistance for gains of 6 dB to

15 dB, easing matching and input drive requirements. The

ADA4960-1 has a nominal 150 Ω differential output resistance.

It is ideally suited for driving not only ADCs, but also mixers,

pin diode attenuators, SAW filters, and multi-element discrete

devices, as well as buffering high frequency DACs. The device

will be available in a single channel version in 3 mm ×3 mm,

16-lead LFCSP package or a dual channel version in 4 mm x 4

mm, 24-lead LFSCP. The device operates over a temperature

range of −40°C to +105°C.

The device is optimized for wideband, low distortion performance

at frequencies up to and beyond 1 GHz. These attributes,

together with its wide gain adjust capability make this device

the amplifier of choice for general-purpose IF and broadband

applications where low distortion, noise, and power are critical.
