Linear Technology has extended its line of low noise, precision operational amplifiers with the addition of the LTC6258/59/60 and LTC6261/62/63 single/dual/quad op amps. The new devices operate on 1.8V to 5.25V supply, feature rail-to-rail inputs and outputs, and include versions with shutdown mode, according to the company.

The devices are fully specified over the industrial (I) (–40°C to 85°C) and extended (H) (–40°C to 125°C) temperature ranges. Input offset voltage is just 400µV max.

With supply current of only 20µA per amplifier, the LTC6258/59/60 achieves 1.3MHz gain bandwidth product and 240V/µs slew rate. They include input EMI filters that provide 45dB rejection at 1GHz. They are stable for any gain and with any capacitive load.

Meanwhile, the LTC6261/62/63 achieves 30MHz GBW product and 7V/µs slew rate, drawing just 240µA per amplifier. Wideband voltage noise is just 13nV/√Hz. They are stable for any gain and for capacitive loads up to 1nF, according to Linear.

The single LTC6258 and LTC6261 are available in 2mm x 2mm DFN package like the dual LTC6259 and LTC6262 as well as 8-lead SOT-23, MSOP-8, and MSOP-10 with shutdown mode. The quad LTC6260 and LTC6263 are available in the MSOP-16 package.
