■GENERAL DESCRIPTION
The XC221A1200MR is an input / output rail to rail CMOS Op
Amp.
With rail to rail functions, operation is guaranteed from power
supplies as low as 1.2V. Moreover, since the XC221A series
comes in an ultra small SOT-25 package, the series is
particularly suited for use with various types of portable
phones. Bandwidths of 550kHz and slew rates of 0.5V can be
achieved even with power consumption as low as 100μA.
Even with large capacitance levels of CL = 200pF (unity gain
connection), the XC221A series will not be susceptible to
oscillation.
