The low input offset voltage holds over temperature and input common mode range: TCVOS is 0.5 μV/°C maximum and CMRR is 124 dB minimum. Open loop gain is typically 142 dB, enabling the device to achieve less than 1 ppm nonlinearity.
The amp has 15 MHz gain-bandwidth product and employs slew enhancement circuitry to achieve up to 30 V/µsec slew rate. The part draws 7.2 mA, which can be reduced during periods of non-use to 6.2 μA using its shutdown pin.
The LT6018 is specified for operation from 8V to 33V supplies, for industrial (–40°C to 85°C) and extended (–40°C to 125°C) temperature ranges. It is available in SO-8E with exposed centre pad for enhanced heat dissipation, and space-saving 4 x 3 mm DFN packages. It is priced starting at $3.25 (1000).
