Difference Amp Uses Unique Level Shifting

Debuting as a unique level-shifting difference amplifier, the INA159 delivers a gain of 0.2 and interfaces ±10V signals to single-supply a/d converters, particularly those with 4.096V or 5V references. The device's amplifier drives converters with resolutions up to 14 bits. Overall specifications include a bandwidth of 15 MHz, slew rate of 15 V/µs, operating voltage from 2.7V to 5V, a maximum offset voltage of 500 µV, maximum gain accuracy of 0.024%, maximum quiescent current of 1.5 mA, and an operating temperature range from -40°C to 125°C. Available in an MSOP8 package, price is $1.59 each/1,000. TEXAS INSTRUMENTS INC., Dallas, TX. (800) 477-8924.
