Voltage Reference draws only 5.6 µA.

Press Release Summary:




Model LT6650 features built-in, rail-to-rail output buffer amplifier and ±1% accuracy from -40 to 85ºC. Operating over 1.4-18 V supply range, unit consumes less than 6 µA with supply levels up to 18 V. Using external gain resistors, output voltage can be adjusted from 400 mV up to positive supply rail using on-chip buffer amp. Device can be configured to operate in shunt or series mode, and output buffer is capable of sourcing or sinking up to 200 µA.

Flexible 400mV Reference Draws Only 5.6uA



MILPITAS, CA - June 28, 2004 - Linear Technology Corporation introduces the LT6650, the lowest voltage series reference available. The device features a built-in rail-to-rail output buffer amplifier and ±1% guaranteed accuracy from -40ºC to 85ºC. The LT6650 is ideally suited for portable industrial and medical equipment, plus low power instrumentation.

Operating over a wide 1.4V to 18V supply range, the LT6650 consumes less than 6uA with supply levels up to 18V. Using external gain resistors, the output voltage can be adjusted from 400mV up to the positive supply rail using the on-chip rail-to-rail buffer amp. The device can be configured to operate in either shunt or series mode, and the output buffer is capable of sourcing or sinking up to 200uA.

Three temperature grades cover the commercial (0ºC to 70ºC), industrial (-40ºC to 85ºC) and automotive (-40ºC to 125ºC) ranges. All grades are in full production. Pricing starts at $1.25 each in 1,000-piece quantities.
