3 Description
The TLV27L2-Q1 single-supply operational amplifiers provide rail-to-rail output capability. The TLV27L2-Q1 device takes the minimum operating supply voltage down to 2.7 V over the extended industrial temperature range, while adding the rail-to-rail output swing feature. The TLV27L2-Q1 device also provides 160-kHz bandwidth from only 7 µA. The maximum recommended supply voltage is 16 V, which allows the devices to be operated from (±8-V supplies down to ±1.35 V) two rechargeable cells.
The rail-to-rail outputs make the TLV27L2-Q1 device good upgrades for the TLC27Lx family of devices which offers more bandwidth at a lower quiescent current. The TLV27L2-Q1 offset voltage is equal to that of the TLC27LxA variant. Their cost effectiveness makes them a good alternative to the TLC225x and TLV225x families of devices, where offset and noise are not of premium importance.
The TLV27L2-Q1 device is available in the commercial temperature range to enable easy migration from the equivalent TLC27Lx.
The TLV27L2-Q1 device is available in an 8-pin SOIC (D) package.
