G1214 致新代理商 功放系列 运算放大器

General Description
致新G1214  is  a  input/output  rail-to-rail  Operational  Ampli-fier. It can be operated from +2.2V to +7V single sup-ply  or  from  ±1.1V  to  ±3.5  dual  supply.  G1214  can  drive 66mA into resistor loads to within 10% power rail. AC  performance  is  very  excellent  with  6.5MHz  band-width,  6.5V/μs  Slew  Rate,  95dB  open  loop  gain,  60  degree phase margin and low distortion. Supply current of G1214 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.   G1214  is  housed  in  a  5-pin  small  SOT-23-5  and  SC-70-5 (SOT-353) package.
