The single / dual / four rail to rail operational amplifiers ltc6252 / 3 / 4 and ltc6255 / 6 / 7 from linear technology corporation provide unparalleled speed power efficiency in a slim package. Ltc6252 / 3 / 4 achieves 720MHz gain bandwidth (GBW) product and 280v / US conversion rate, and consumes only 3.3ma power supply current. Ltc6255 / 6 / 7 provides 6.5mhz gain bandwidth product and 1.8v/us conversion rate, consuming only 65ua power supply current. These devices, combined with the ltc6246 / 7 / 8 with 180mhz gain bandwidth and 1mA supply current, provide a series of high efficiency operational amplifiers suitable for various applications.

720MHz, 3.3maltc6252 / 3 / 4, low input reference broadband noise of 2.75nv / √ Hz and 280v / μ s conversion rate. This high-speed performance combines dc accuracy: the input offset voltage is 350uv (maximum) at room temperature and 1mV (maximum) at – 40 ° C to 125 ° C. The device uses 2.5V to 5.25V power supply, and has rail to rail input and output as well as fast output over drive recovery function.

The 6.5mhz, 65ua ltc6255 / 6 / 7 also has rail to rail inputs and outputs. These devices are unity gain stable and can drive capacitive loads up to 100nF. These devices are guaranteed to work in the supply voltage range of 1.8V to 5.25V. The maximum input offset voltage is 350 UVs at 25 ° C and 700 UVs at – 40 ° C to 125 ° C. Applications include portable instruments, battery and solar power systems, and automotive electronics.

The dual ltc6253 and ltc6256 are packaged in 2mmx2mm DFN and 8-Lead SOT-23. You can also choose MSOP package, including 8-Lead and 10 lead versions with shutdown function. The single channel ltc6252 and ltc6255 also have shutdown function and adopt SOT-23 package. The four way ltc6254 and ltc6257 are packaged in 16 lead MSOP. These amplifiers are fully specified for operation in the commercial (0oC to 70oC), industrial (- 40oC to 85oc) and high temperature industrial H-class (- 40oC to 125oC) temperature ranges. They are purchased in batches of 2500 pieces, and the price of each ltc6255cs6? Trpbf is $1.24. For more information, please login and.
