XC221A Series ETR1201_001 1.2V Input / Output Rail To Rail CMOS Op Amp ■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 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. ■APPLICATIONS ■FEATURES ●Palmtop computers, PDAs Operating Voltage Range:1.2 ~ 10V (single cell) :±0.6 ~ 5V (+ve/-ve supply) ●Cellular and portable phones ●Portable audio systems ●Various battery powered systems 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 Ultra Small Package ■PIN CONFIGURATION :SOT-25 ■PIN ASSIGNMENT PIN NUMBER 1 SYMBOL FUNCTION VOUT Output Pin 2 VDD Positive Power Supply Pin 3 IN+ Positive Input 4 IN- Negative Input 5 VSS Negative Power Supply Pin 1/9 XC221A Series ■PRODUCT CLASSIFICATION ●Ordering Information XC221A①②③④⑤⑥ DESIGNATOR DESCRIPTION SYMBOL DESCRIPTION ① The Number of Channels 1 : One channel ② Supply Current 1 : 15μA 2 : 100μA ③ Internal Standard Number 0 : Fixed ④ Load Capacitance 0 : 200pF ⑤ Package M : SOT-25 (SOT-23-5) ⑥ Device Orientation R : Embossed tape, standard feed L : Embossed tape, reverse feed ■ABSOLUTE MAXIMUM RATINGS Ta = 25℃, VSS = 0V PARAMETER SYMBOL RATINGS UNITS VDD Pin Voltage VDD -0.3 ～ 12.0 V OUT Pin Voltage IN Pin Voltage VOUT VIN+ -0.3 ～ 12.0 -0.3～VDD+0.3 V V IN/ Pin Voltage VIN- -0.3～VDD+0.3 V OUT Pin Current IOUT ±100 mA Power Dissipation Pd 150 mW Operating Temperature Range Topr -30 ～ +80 ℃ Storage Temperature Range Tstg -40 ～ +125 ℃ RAIL-TO-RAIL is a trademark of Motorola. 2/9 XC221A Series ■ELECTRICAL CHARACTERISTICS XC221A1100 PARAMETER IDD =15μA SYMBOL CONDITIONS Ta = 25℃ UNITS MIN.
