The ADA4807-1/ADA4807-2 are low power, low noise, rail-to-rail voltage feedback amplifiers with exceptionally high performance. They are designed to have the lowest input noise (3.1 nV/√Hz and 0.7 pA/√Hz) among high speed, rail-to-rail amplifiers in the industry while operating on only 1 mA or less of quiescent supply current, making them ideal for a wide range of applications from battery-powered, portable instrumentation to high speed systems where component density requires lower power dissipation. The ADA4807 operate over a wide range of supply voltages from ±1.5 V to ±5 V, as well as from 3 V to 10 V single supplies, and include a disable feature that allows reduction of the typical quiescent supply current to 2.4 μA or less when asserted.For systems with high dynamic range signals, the output voltage swings to within 50 mV of each rail, maximizing the output cdynamic range, and the full, rail-to-rail input stage permits input operation up to and beyond the supply rails.The ADA4807 feature high speed performance of 180 MHz small signal −3 dB bandwidth, a 225 V/μs slew rate, and a settling time of 47 ns to 0.1% (4 V step) with a low input offset voltage of ±20 μV and 0.7 μV/°C drift. For ±5 V supplies, the HD2 is −112 dBc and HD3 is –115 dBc for a 2 V p-p, 100 kHz output signal driving a 1 kΩ load. The low distortion and fast settling time make these amplifiers ideal for driving high speed single-supply precision ADCs with up to 18-bit resolution. The ADA4807 deliver this excellent performance while consuming 1 mA or less of quiescent current.The ADA4807-1 (single) is available in space-saving 6-lead SC70 and 6-lead SOT-23 packages. The ADA4807-2 (dual) is available in 10-lead LFCSP and 8-lead MSOP packages.

The AD8072 (dual) and AD8073 (triple) are low cost, current feedback amplifiers intended for high volume, cost sensitive applications. In addition to being low cost, these amplifiers deliver solid video performance into a 150 (ohm) load while consuming only 3.5 mA per amplifier of supply current. Furthermore, the AD8073 is three amplifiers in a single 14-pin narrow-body SOIC package. This makes it ideal for applications where small size is essential. Each amplifier’s inputs and output are accessible providing added gain setting flexibility.These devices provide 30 mA of output current per amplifier, and are optimized for driving one back terminated video load (150 (ohm)) each. These current feedback amplifiers feature gain flatness of 0.1 dB to 10 MHz while offering differential gain and phase error of 0.05% and 0.1°. This makes the AD8072 and AD8073 ideal for business and consumer video electronics.Both will operate from a single +5 V to +12 V power supply. The outputs of each amplifier swing to within 1.3 volts of either supply rail to accommodate video signals on a single +5 V supply.The high bandwidth of 100 MHz, 500 V/µs of slew rate, along with settling to 0.1% in 25 ns, make the AD8072 and AD8073 useful in many general purpose, high speed applications where a single +5 V or dual power supplies up to ±6 V are needed. The AD8072 is available in 8-pin plastic DIP and SOIC packages while the AD8073 is available in 14-pin plastic DIP and SOIC packages. Both operate over the commercial temperature range of 0°C to +70°C.

Theyare designed for balanced data transmission and comply with EIA Standards RS-485 and RS-422. The ADM4850 / ADM4851 / ADM4852 / ADM4853 are half-duplex transceivers that sharedifferential lines and have separate enable inputs for the driver and receiver. The full duplex ADM4854 / ADM4855 / ADM4856 / ADM4857 transceivers have dedicated differential line driveroutputs and receiver inputs.The devices have a 1/8-unit load receiver input impedance, which allows up to 256 transceivers on one bus. Because only onedriver must be enabled at any time, the output of a disabled or powered down driver is three-stated to avoid overloading the bus.The receiver inputs have a true fail-safe feature, which ensures a logic high output level when the inputs are open or shorted.This guarantees that the receiver outputs are in a known state before communication begins and when communication ends.The driver outputs are slew rate limited to reduce EMI and data errors caused by reflections from improperly terminated buses.Excessive power dissipation caused by bus contention or by output shorting is prevented with a thermal shutdown circuit.The devices are fully specified over the commercial and industrial temperature ranges and are available in 8-lead SOIC (ADM4850through ADM4857), 8-lead LFCSP (ADM4850 / ADM4852 / ADM4853), and 8-lead MSOP (ADM4850 only) packages.Applications Low power RS-485 applications EMI sensitive systems DTE to DCE interfaces Industrial control Packet switching Local area networks Level translators
