Analog Devices' differential high-speed amplifiers are designed to deliver a combination of low noise, low distortion and wide dynamic range - suitable for driving high-speed, analog-to-digital converters (ADCs). The AD8139 and AD8137 are designed to address the performance required to drive 12- to 18-bit ADCs that are critical in high-bandwidth instrumentation, communications, military, and industrial applications. With The AD8139 has 1.9 nV/rt-Hz input referred noise, 115 dBc SFDR (spurious-free dynamic range) at 1 MHz, and 370 MHz bandwidth. Rail-to-rail output allows the amplifier's dynamic range to be used without headroom constraints, enabling the device to drive 16-bit and higher resolution ADCs on a 5 V supply. The AD8137 provides a rail-to-rail output stage, 110 MHz bandwidth, and a 450 V/us slew rate, while consuming 2.3 mA of quiescent current. The device is suitable for battery-operated applications and 10- to 14-bit data acquisition systems. The AD8137 offers a supply-voltage range from 3 to 12 V.
