TI Introduces Unique Level-Shifting Difference Amplifier for Data Acquisition, Industrial Control and Test Equipment
DALLAS (October 6, 2005) - Texas Instruments Incorporated (TI) (NYSE: TXN) today announced a unique level-shifting difference amplifier from the company's Burr-Brown product line. Featuring a gain of 0.2, the INA159 is designed to interface +/-10V signals to single supply analog-to-digital converters (ADCs), especially those with 4.096V or 5V references. When combined with an economical single supply ADC, the INA159 provides a high accuracy, easy-to-use, cost competitive solution compared to a +/-10V input ADC. Targeted applications for this device include data acquisition, industrial process control and test equipment. (See www.ti.com/sc05212.)
Prior to the introduction of the INA159, functionality was achieved using complicated and expensive precision resistor networks and a high performance op amp. The amplifier in the INA159 is especially suited for driving up to 14-bit ADCs, such as TI's ADS8324, with its 1.5MHz bandwidth and 15V/us slew rate, along with low output impedance. A split reference connection simplifies biasing at one half supply or reference and eliminates the need for an additional op amp.
Single supply voltage range is from 2.7V to 5.5V. The device features low offset (500uV maximum), high gain accuracy (0.024 percent maximum), low quiescent current (1.5mA maximum) and specification over a -40C to +125C temperature range.
Available Today
The INA159 is available now from TI and its authorized distributors. The device is available in a space-saving MSOP8 package and is priced from $1.59 in 1,000 piece quantities (suggested resale pricing).
