1.8V INPUT/OUTPUT RAIL TO RAIL
LOW POWER OPERATIONAL AMPLIFIERS
s OPERATING AT VCC = 1.8V to 6V
s RAIL TO RAIL INPUT & OUTPUT
s EXTENDED Vicm (Vee - 0.2V to VCC + 0.2V)
s LOW SUPPLY CURRENT (400µA)
s GAIN BANDWIDTH PRODUCT (1.6MHz)
s HIGH STABILITY
s ESD TOLERANCE (2kV)
s LATCH-UP IMMUNITY
s AVAILABLE IN SOT23-5 MICROPACKAGE
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 600W load resistor. This I/O Rail to Rail configu-
ration gives the chance to the user to have the en-
tire supply voltage range available. Offering 20mA
min., 65mA typ. value and exhibiting an excellent
speed-power ratio, 1.6MHz GBP & 400µA 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.
APPLICATION
s Battery-powered applications
s Portable communication devices (cell phone)
s Active filters
s Audio driver
