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 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.
The XC221A series is a rail‑to‑rail CMOS operational amplifier designed for low‑voltage, battery‑powered applications. It operates from 1.2 V to 10 V supply and offers rail‑to‑rail input and output with low supply current.
The device is supplied in an ultra‑small SOT‑25 package, supports up to 200 pF load capacitance, and provides a gain‑bandwidth of 550 kHz with a 0.5 V/µs slew rate. Typical applications include portable computers, phones, audio systems and other battery‑driven equipment.
