The proprietary circuit topology of this amplifier gives excellent slew rate at low quiescent power dissipation without compromising precision or settling time. In addition, unique input stage circuitry allows the input impedance to remain high during input voltage steps as large as 5V. The combination of preci - sion specs along with fast settling makes this part ideal for MUX applications. The low quiescent current of the LT6020 along with its ability to operate on supplies as low as 3V make it useful in portable systems. The LT6020-1 features a shutdown mode which reduces the typical supply current to 1.4μA. The LT6020 is available in the small 8-lead DFN and 8-lead MSOP packages. The LT6020-1 is available in a 10-lead DFN package. 16-Bit DAC with ±10V Output Swing

Exposure to any Absolute Maximum Rating condition for extended periods may affect device reliability and lifetime. Note 2: Guaranteed by design. Note 3: The slew rate of the LT6020 increases with the size of the input step. At lower supplies, the input step size is limited by the input common mode range. This trend can be seen in the Typical Performance Characteristics.

Normally an amplifier with higher supply current would be required to achieve this combination of slew rate and precision. Special care must be taken to ensure that the low power operation is preserved. The choice of feedback resistor values impacts several op-amp parameters as noted in the feedback compo - nents section. It should also be noted that the output of the amplifier must drive this network. For example, in a gain of two with a total feedback resistance of 10kΩ and an output voltage of 14V, the amplifier’s output will need to supply 1.4mA of current. This current will ultimately come from a supply.
