Features ■ Operating range from Vcc = 1.8 to 6 V ■ Rail-to-rail input and output ■ Extended V^ (Vcc- - 0.2 V to Vcc + + 0.2 V) ■ Low supply current (120 pA) ■ 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 kQ), 120 pA 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). Table 1. Device summary

TS185x, TS185xA Absolute maximum ratings and operating conditions Table 2. Absolute maximum ratings 1. All voltage values, except differential voltages, are with respect to network terminal. 2. Differential voltages are the non-inverting input terminal with respect to the inverting input terminal. If Vid > ±1 V, the maximum input current must not exceed ±1 mA. When Vjd > ±1 V, add an input series resistor to limit the input current. 3. Short-circuits can cause excessive heating. Destructive dissipation can result from simultaneous short-circuits on all amplifiers. 4. Human body model: a 100 pF...
