STMicroelectronics has introduced two families of rail-to-rail high gain-bandwidth product (GBP) op-amps that feature an excellent speed-to-current consumption ratio and are housed in space-saving packages to address sensor signal conditioning as well as battery-supplied and compact portable applications.

The TSV911/2/4 family provides an 8 MHz gain-bandwidth product and is unity-gain stable for capacitive loads up to 200 pF. The second family, the TSV991/2/4, exhibits a 20 MHz gain-bandwidth product for a gain of 3 or above.

Operating from 2.5 V to 5.5 V, the devices consume only 780 microamperes at a 2.5 V supply voltage. The low power requirements, together with their improved precision and reduced die size, make the devices well suited for battery-powered applications where low circuit board real estate and low current consumption are major priorities.

Other key features of these op-amps include an ultralow input bias current of 1 picoampere and 5 kV or better internal protection that guards against electrostatic discharge (ESD), minimizing handling and assembly risks.

All of the amplifiers are characterized over a -40 to +125 degree C temperature range and are available in SOT23-5, SO8, MSO8, TSSOP14, and SO14 ECOPACK packages.

In production now, in quantities of 1000 pieces, the unit prices for the TSV911/TSV991, TSV912/TSV992, and TSV914/TSV994 are $ 0.36, $ 0.62, and $ 0.96, respectively.
