The AD8034 and AD8065 combine wide supply voltage range, low input bias current and noise, low distortion, low voltage noise, low offset voltage and drift and rail-to-rail output. In addition, both products come in very small packaging, for use on even the most space-constrained boards. These performance levels at low cost are possible using Analog Devices’ proprietary XFCB high-speed complementary bipolar process.

The AD8065 is a very high performance single voltage-feedback amplifier with FET inputs, with a dual version in development.

The AD8065 is noteworthy for its very low noise, at 6.5nV/rtHz and 5fA/rtHz, and very low distortion, -91dB SFDR at 1MHz.

The device operates at 150MHz with a slew rate of 180V/us.

The AD8065 also has superior DC performance, with an IB of 1pA typical, an offset voltage of 6uV typical, and a drift of less than 1mV/C.

The differential gain and phase errors are 0.01% and 0.02deg, with 0.1-dB flatness out to 7MHz, making the part ideal for video applications.

The AD8065 consumes 6.5mA supply current.

The AD8034 is a dual voltage feedback amplifier with FET inputs, with a single version in development.

The AD8034 is a lower priced version of the AD8065 offering similarly high performance while consuming only 3.3mA supply current maximum per amplifier.

With 80MHz bandwidth, slew rate of 80V/us, and low DC errors of 6mV offset voltage and 11nV/rtHz noise, the AD8034 offers significant performance improvements over other low-cost FET amplifiers.

A wide operating supply voltage range of 5 to 24V with rail-to-rail output add to the general usefulness of these amplifiers.

The AD8034 and AD8065 are sampling now and are available in very small SOIC-8, SOT23-5 and micro-SOIC packages.
