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 V CC = 1.8 V, RL =2k Ω), 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). Table 1. Device summary

  1. Machine model: a 200 pF capacitor is charged to the specified voltage, then discharged directly between

connected pin combinations while the other pins are floating.

  1. Charged device model: all pins and package are ch arged together to the specified voltage and then

discharged directly to ground through only one pin. This is done for all pins.

  1. Short-circuits from the output to V CC can cause excessive heating. The maximum output current is

simultaneous short-circuits on all amplifiers.
