General Description

G1244  is  a  input/output  rail-to-rail  Operational  Ampli-fier. It can be operated from +3V to +5.5V single sup-ply  or  from  ±1.5V  to  ±2.75  dual  supply.  G1244  can  drive 66mA into resistor loads to within 10% power rail each  amplifier.  AC  performance  is  very  excellent  with  2.5MHz bandwidth, 6V/μs Slew Rate, 95dB open loop gain, 60 degree phase margin and low distortion.

Supply current of G1244 is only 500μA per Amplifier. It is  very  suitable  for  low  current  consumption  applica-tions to control high current loads. Applications include audio  amplification  for  computers,  sound  ports,  sound  cards and set-top boxes.  

G1244 is available in 14-pins TSSOP package.
