Overview
TS187x, TS187xA 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 (400 µA) ■ Gain bandwidth product (1.
6 MHz) ■ High unity gain stability ■ ESD tolerance (2 kV) ■ Latch-up immunity ■ Available in – SOT23-5 micropackage – MiniSO-8, SO-8, SO-14 – TSSOP8, TSSOP14 package Applications ■ Battery powered applications (toys) ■ Portable communication devices (cell phones) ■ Audio drivers (headphone drivers) ■ Laptop/notebook computers Description The TS187x (single, dual and quad) device can operate with voltages as low as 1.
8 V.
They feature both input and output rail-to-rail.
The common mode input voltage extends 200 mV beyond the supply voltages at 25 °C, while the output voltage swing is within 100 mV of each rail with a 600 Ω load resistor.
The devices consume typically 400 µA per channel while offering 1.
6 MHz of gain bandwidth product.
The amplifiers provide a high output drive capability at typically 65 mA loads.
These features make the TS187x family ideal for sensor interface, battery supplied and portable applications.
