DESCRIPTION

The TS187x (Single, Dual & Quad) is operational

amplifier able to operate with voltages as low as

1.8V and features both I/O Rail to Rail.

The common mode input voltage extends 200mV

@25

°C beyond the supply voltages while the out-

put voltage swing is within 100mV of each Rail for a

600

Ω load resistor. This I/O Rail to Rail configura-

tion gives the chance to the user to have the entire

supply voltage range available. Offering 20mA

min., 65mA typ. value and exhibiting an excellent

speed-power ratio, 1.6MHz GBP & 400

µA supply

current, this Op-Amp is very well-suited for bat-

tery-supplied and portable applications.

Stability and minimum overshoot with capacitive

loads is maintained by 53

° typ. of phase margin

with 100pF load capacitor @ 1.8V.
