2 / 12 page UC2838, UC2838A UC3838, UC3838A SLUS221A – APRIL 2000 – REVISED MAY 2001 2 www.ti.com description (continued) The UC3838/A contains a precision 2.5-V reference, two uncommitted high-gain operational amplifier and a high-gain PNP-equivalent current source which can deliver up to 100 mA of magnetic amplifier reset current and with –120-V capability. These devices are available in a plastic batwing DIP (N), wide body SOIC (DW), and PLCC (Q) package for operation over a –20 °C to 85°C temperature range. 19 20 1 32 17 18 16 15 14 13 12 11 9 10 5 4 6 7 8 RESET N/C N/C GND VM C/L INV.IN GND N/C N/C E/A INV.IN Q PACKAGE (TOP VIEW) 1 2 3 4 5 6 7 8 16 15 14 13 12 11 10 9 C/L OUT C/L N.I.

These are stress ratings only, and functional operation of the device at these or any other conditions beyond those indicated under “recommended operating conditions” is not implied. Exposure to absolute-maximum-rated conditions for extended periods may affect device reliability. ‡ All voltages are with respect to ground pins. All currents are positive into the specified terminal. Consult packaging section of data book for thermal limitations and considerations of package. |
