Texas Instruments Incorporated (TI) (NYSE: TXN) today introduced the industry's first zero-drift, 36-V operational amplifier (op amp). Compared to the competition, the dual-channel OPA2188 provides a 4x improvement in offset voltage drift, 60 percent improvement in initial offset voltage and twice the bandwidth at the same power consumption. The OPA2188 can be used in high- and low-voltage supply applications requiring ultra-high precision, such as test and measurement equipment, electronic weigh scales, medical instrumentation and flow meters.

"Our design teams have achieved leading performance levels for ultra-low noise, EMI and RFI input filtering, and low power consumption. These efforts will help our customers achieve higher efficiencies in applications like control and automation, and higher accuracy in portable medical designs." Key features and benefits Zero drift architecture, 0.03 uV/degree C, reduces the need for future system calibration. Initial offset voltage of 25 uV enables the highest-resolution sensor measurement in its class. Provides 2 MHz of bandwidth while consuming only 475 uA of quiescent current, which will enable portable medical applications to provide even higher levels of accuracy. Low noise of 8.8 nV/rtHz for high system precision. Input common mode range extending from negative rail to within 1.5 V of the positive rail saves additional circuitry and enables 5-V, single-supply operation. Tools and support TI offers a variety of tools and support to speed development with the OPA2188, including:
