AD847:  High Speed, Low Power Monolithic Op Amp

Product Details


The AD847 represents a breakthrough in high speed amplifiers offing superior ac & dc perfomance and low power, all at low cost. The excellent dc performance is demonstrated by its ±5 V specifications which include an open-loop gain of 3500 V/V (500 Ohm load) and low input offset voltage of 0.5 mV. Common-mode rejection is a minimum of 78 dB. Output voltage swing is ±3 V into loads as low as 150 Ohm. Analog Devices also offers over 30 other high speed amplifiers from the low noise AD829 (1.7nV/(root)Hz) to the ultimate video amplifier, the AD811, which features 0.01% differential gain and 0.01° differential phase.

AN-417: Fast Rail-to-Rail Operational Amplifiers Ease Design Constraints in Low Voltage High Speed Systems  (pdf, 228 kB)
Movement towards lower power supply voltages is driven by the demand that systems consume less and less power coupled with the desire to reduce the number of power supply voltages in the system. The following applications are discussed: Single-Ended and Differential Input ADC Input Circuits, Video Line Driver, Active Filter, HDSL Transceiver, and Transformer Drive Circuits.
