STMicroelectronics boosts all-round performance in op amps for industrial and automotive environments

STMicroelectronics is simplifying designers’ search for high-performing operational amplifiers (op amps) by introducing three new 6MHz rail-to-rail devices with strong all-round parameters including a wide operating-voltage range and low noise.

The TSB511, TSB512, and TSB514 are single, dual, and quad op amps, respectively. They can operate from a single supply in the range from 2.7V to 36V, and with dual supplies from ±1.35V to ±18V. This wide voltage range and flexibility let engineers benefit from applying a familiar op-amp type across various applications and different power domains. The rail-to-rail input and output help ensure suitable dynamic range when operating close to the minimum supply voltage.

Input noise density of 12nV/√Hz allows use in circuits where signal integrity is a priority, particularly with weak or wideband signals. In addition, the fast slew rate of 3V/µs saves trading signal amplitude and frequency range in filter and amplifier circuits. The maximum offset voltage of 1.5mV ensures good accuracy and precision for control and measurement applications (more info).
