Description
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.
