Texas Instruments introduced an operational amplifier (op-amp) it claims is the first to offer both zero-drift and zero-crossover technology. The OPA388 maintains high precision across the entire input range for a variety of industrial applications, including test and measurement, medical and safety equipment, and high-resolution data acquisition systems.
The unique architecture of the IC produces a combination of ultra-high input linearity and precision. TI’s zero-drift technology eliminates temperature drift and flicker noise to attain the highest DC precision and dynamic error correction, while its zero-crossover topology eliminates offset errors caused by common-mode limitations to achieve linear output and true rail-to-rail input operation.
The device’s zero-crossover topology eliminates the input offset transition region of traditional complementary metal-oxide semiconductor (CMOS) op-amps, assuring maximum linearity and minimal distortion across the entire common-mode input range. Its zero-drift technology delivers a low maximum offset voltage of 5 µV, a typical offset voltage drift of 0,005 V/°C and a maximum input bias current of 700 pA over the extended industrial temperature range of -40°C to 125°C. This eliminates the need for costly over-temperature calibration and increases DC precision.
With a 10 MHz gain bandwidth product (GBW), the OPA388 enables high gain configurations and makes it possible to acquire a wide range of signal types and frequencies to support equipment from precision weigh scales to heart-rate monitors. The ultra-low total harmonic distortion of -132 dBc and voltage noise of 7 nV/Hz help produce a high-resolution signal chain for specialised applications such as programmable logic controllers, precision field transmitters and motion control equipment.
