The combination of high slew rate, 1.0A output drive and ±15V operation enables the device to deliver significant power at frequencies in the 1MHz to 2MHz range. Shortcircuit protection ensures the device’s ruggedness. The LT1210X is stable with large capacitive loads, and can easily supply the large currents required by the capacitive loading. A shutdown feature switches the device into a high impedance and low supply current mode, reducing dissipation when the device is not in use. For lower bandwidth applications, the supply current can be reduced with a single external resistor. 80mils × 134mils, 12mils thick. Backside metal: TiNiAg Backside potential: V+ 1. V+: Positive Supply Voltage. V+ and V– must be chosen so that 10V ≤ (V+ – V–) < 36V. Both Pad 1 and Pad 4 must be connected to V+. 2. OUT: Amplifier Output. The output can source/sink a minimum of 1A. Both Pad 2 and Pad 3 must be connected to OUT. 3. OUT: Amplifier Output. The output can source/sink a minimum of 1A. Both Pad 2 and Pad 3 must be connected to OUT. 4. V+: Positive Supply Voltage. V+ and V– must be chosen so that 10V ≤ (V+ – V–) < 36V. Both Pad 1 and Pad 4 must be connected to V+. 5. –IN: Inverting Input of Amplifier. Valid input range is ±12V on ±15V supplies. 6. +IN: Noninverting Input of Amplifier. Valid input range is ±12V on ±15V supplies. 7. SHUTDOWN: If the shutdown feature is not used, the SHUTDOWN pin must be connected to Ground or V–. The SHUTDOWN pin can be used to either turn off the biasing for the amplifier, reducing the quiescent current to less than 200μA, or to control the quiescent current in normal operation. 8. COMP: Adding a 0.01µF capacitor between the output and the COMP pin greatly reduces peaking when driving capacitive loads. To disconnect the optional compensation, leave the COMP pin open. 9. V–: Negative Supply Voltage. V+ and V– must be chosen so that 10V ≤ (V+ – V–) < 36V. This is a double pad (shared with Pad 10). 10. V–: Negative Supply Voltage. V+ and V– must be chosen so that 10V ≤ (V+ – V–) < 36V. This is a double pad (shared with Pad 9). 1 LT1210X DICE/DWF ABSOLUTE MAXIMUM RATINGS Supply Voltage ...................................................... ± 18V Input Current........................................................ ±15mA Output Short-Circuit Duration (Note 2)...........................................Thermally Limited ELECTRICAL CHARACTERISTICS otherwise noted.
