Operating Voltage Range (Single Cell) 1.2V to 10V Input / Output Rail To Rail Operation Gain Bandwidth 550kHz Slew Rate 0.5V / S Low Power Consumption 100A SOT - 25 Ultra Small Package
Applications
Palmtop computers, PDAs Cellular and portable phones Portable audio systems Various battery powered systems
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 XC221 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 100A. Even with large capacitance levels of CL = 200pF (unity gain connection), the XC221 will not be susceptible to oscillation.
