TSX7192 Low-power, precision, rail-to-rail, 9.0 MHz, 16 V operational amplifiers Datasheet - production data Description The TSX7192 dual, operational amplifier (op amp) offers high precision functioning with low input offset voltage down to a maximum of 200 V at 25 C. In addition, its rail-to-rail input and output functionality allows this product to be used on full range input and output without limitation. This is particularly useful for a low- voltage supply such as 2.7 V that the TSX7192 is able to operate with. Features Thus, the TSX7192 has the great advantage of offering a large span of supply voltages, ranging Low input offset voltage: 200 V max. from 2.7 V to 16 V. It can be used in multiple Rail-to-rail input and output applications with a unique reference. Low current consumption: 850 A max. Gain bandwidth product: 9 MHz Low input bias current performance makes the Low supply voltage: 2.7 to 16 V TSX7192 perfect when used for signal Stable when used with Gain 10 conditioning in sensor interface applications. In Low input bias current: 50 pA max. addition, low-side and high-side current High ESD tolerance: 4 kV HBM measurements can be easily made thanks to rail- to-rail functionality. The TSX7192 is a Extended temp. range: -40 C to 125 C decompensated amplifier and must be used with Automotive qualification a gain greater than 10 to ensure stability. Related products High ESD tolerance (4 kV HBM) and a wide temperature range are also good arguments to See the TSX7191 for single op amp version use the TSX7192 in the automotive market See the TSX712 for lower speeds with segment. similar precision See the TSX562 for low-power features See the TSX632 for micro-power features See the TSX922 for higher speeds Applications Battery-powered instrumentation Instrumentation amplifier Active filtering High-impedance sensor interface Current sensing (high and low side) March 2015 DocID027196 Rev 1 1/25 www.st.com This is information on a product in full production.
