(LT6001 / LT6002) Rail-to-Rail Op Amps

www.DataSheet4U.com LT6001/LT6002 Dual and Quad, 1.8V, 13µA Precision Rail-to-Rail Op Amps FEATURES ■ DESCRIPTIO ■ ■ ■ ■ ■ Ideal for Battery-Powered Applications – Low Voltage: 1.8V Operation – Low Current: 16µA/Amplifier Max – Small Packages: DFN, MSOP, SSOP – Shutdown to 1.5µA Max (LT6001DD) Low Offset Voltage: 500µV Max Rail-to-Rail Input and Output Fully Specified on 1.8V and 5V Supplies Operating Temperature Range: –40°C to 85°C Available in 10-Lead and 16-Lead DFN, 8-Lead MSOP and 16-Lead SSOP Packages APPLICATIO S ■ ■ ■ ■ ■ The LT®6001/LT6002 are dual and quad precision rail-torail input and output operational amplifiers. Designed to maximize battery life in always-on applications, the devices will operate on supplies down to 1.8V while drawing only 13µA quiescient current. The low supply current and low voltage operation is combined with precision specifications; input offset is guaranteed less than 500µV. The performance on 1.8V supplies is fully specified and guaranteed over temperature. A shutdown feature in the 10lead dual version can be used to extend battery life by allowing the amplifiers to be switched off during periods of inactivity. The LT6001 is available in the 8-Pin MSOP package; a 10-lead version with the shutdown feature is available in a tiny, dual fine pitch leadless package (DFN). The quad LT6002 is available in the 16-pin SSOP package and the 16-pin DFN package. These devices are specified over the commercial and industrial temperature range. , LTC and LT are registered trademarks of Linear Technology Corporation.
