■PIN CONFIGURATION ■FEATURES Operating Voltage Range:1.2 ~ 10V (single cell) : ±0.6 ~ 5V (+ve/-ve supply) Output Signal : 0.1~2.9V (3V single cell, RL=2kΩ) Gain Bandwidth : 550kHz (15μA: 210kHz) Slew Rate : 0.5V/μs High Capacitance Load : CL=200pF Low Supply Current : 100μA, 15μA Input / Output Rail To Rail Operation Package : SOT-25 Environmentally Friendly:EU RoHS Compliant, Pb Free ■APPLICATIONS

  • Palmtop computers, PDAs
  • Cellular and portable phones
  • Portable audio systems
  • Various battery powered systems ■PIN ASSIGNMENT ■GENERAL DESCRIPTION The XC221A series 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 partic ularly 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 gai n connection), the XC221A series will not be susceptible to oscillation. ETR1201_002
