Linear Technology announces the LT6220, LT6221 and LT6222 single, dual and quad rail-to-rail input and output precision op amps. Drawing less than 1mA per channel, these 60 MHz op amps increase the operation time of wide bandwidth battery-powered systems without compromising performance. The LT6220/21/22 can operate from supplies as low as 2.3V and up to 12.6V, while the entire supply range is available because of the devices' rail-to-rail inputs and outputs. The devices have a maximum input offset voltage of 350uV, maximum input bias current of 150nA, CMRR of 82dB and voltage gain of 90dB. Output current capability is 50mA for driving heavier loads, even with a low supply current of less than 1mA/amplifier. Fully specified over the commercial temperature range of 0°C to 70°C and industrial temperature range of 40°C to 85°C, the LT6220 single is offered in the 5-pin SOT23 and 8-pin SOIC packages. The LT6221 dual is available in the 8-pin SOIC and 3 × 3 mm DFN package. The LT6222 quad is available in the 16-pin SSOP, which has the same footprint of an SO-8 package.
