They feature a low distortion rail-to-rail output stage, 700V/µs slew rate and a minimum output current drive of 75mA. n L, LT, LTC, LTM, Linear Technology and the Linear logo are registered trademarks and C-Load and ThinSOT are trademarks of Linear Technology Corporation. All other trademarks are the property of their respective owners. Typical Application The LT6210/LT6211 operate on supplies as low as a single 3V and up to either 12V or ±6V. The ISET pin allows for the optimization of quiescent current for specific bandwidth, distortion or slew rate requirements. Regardless of supply voltage, the supply current is programmable from just 300µA to 6mA per amplifier with an external resistor or current source. The LT6210 is available in the low profile (1mm) 6-lead TSOT-23 package. The LT6211 is available in the 10-lead MSOP and the 3mm × 3mm × 0.8mm DFN packages.
