TS1852A

TS185x, TS185xA 1.8 V input/output, rail-to-rail, low power operational amplifiers Features ■ Operating range from VCC = 1.8 to 6 V ■ Rail-to-rail input and output ■ Extended Vicm (VCC- - 0.2 V to VCC + + 0.2 V) ■ Low supply current (120 μA) ■ Good accuracy (1 mV max for A version) ■ Gain bandwidth product (530 kHz) ■ High unity gain stability (able to drive 500 pF) ■ ESD tolerance (2 kV) ■ Latch-up immunity ■ Available in SOT23-5 micropackage Applications ■ Two-cell battery-powered systems ■ Battery-powered electronic equipment ■ Cordless phones ■ Cellular phones ■ Laptops ■ PDAs Description The TS185x (single, dual and quad) can operate with voltages as low as 1.8 V. They feature both input and output rail-to-rail (1.71 at VCC = 1.8 V, RL = 2 kΩ), 120 μA current consumption and 530 kHz gain bandwidth product. With this low consumption and a sufficient GBP for many applications, these operational amplifiers are well-suited to all kinds of battery supplied and portable applications. The TS1851 is housed in the space-saving 5-pin SOT23-5 package, which simplifies board design (outside dimensions are 2.8 mm x 2.9 mm).
