CMOS operational amplifiers offer precision performance at competitive prices

Texas Instruments’ OPA317-Q1 series of CMOS operational amplifiers offer precision performance at a very competitive price. These devices are members of the Zerø-Drift family of amplifiers that use a proprietary autocalibration technique to simultaneously provide low offset voltage (90µV maximum) and near-zero drift over time and temperature at only 35µA (maximum) of quiescent current. The device family features rail-to-rail input and output in addition to near flat 1/f noise, making this amplifier ideal for many applications, and much easier to design into a system. These devices are optimised for low-voltage operation as low as 1.8V (±0.9V) and up to 5.5V (±2.75V). The single version is available in the SOT23-5 package. The dual version is offered in the VSSOP-8 package. It is also offered in the TSSOP-14 package. All versions are specified for operation from -40C to +125C.
