The CXAS42244 CXAS42245 CXAS42246 consists of one independent, high gain, internally frequency compensated operational amplifiers which was designed to operate from a single power supply over a wide range of voltages. Operation from split power supplies is also possible. The input common mode range of the CXAS42244 CXAS42245 CXAS42246 can be beyond the rails, and the CXAS42244 CXAS42245 CXAS42246 is with rail-to-rails output voltage swing. The quiescent current is 5.5mA, typically. The CXAS42244 CXAS42245 CXAS42246 also feature fast slewing and settle-times, as well as high output drive capability of 1300mA (source/sink). These features make this amplifier ideal for use as reference buffers for TFT-LCD. Other applications include battery power, portable devices, and anywhere low power consumption is important. The CXAS42244 CXAS42245 CXAS42246 is housed in a TDFN3X3-8 package.
