Three op amps ensure dynamic range at minimum supply voltage
Three op amps, the TSB511, TSB512 and TSB514 are single, dual, and quad op amps, respectively. They are designed to boost performance for industry and automotive environments, said the company.
The 6MHz rail-to-rail devices have strong all-round parameters including a wide operating voltage range and low noise.
They can operate from a single supply in the range from 2.7 to 36V and with dual supplies from ±1.35 to ±18V. The voltage range and flexibility of all three op amps are a familiar format that can be applied 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 per microsecond 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, added ST.
The TSB511, TSB512, and TSB514 are suitable for use in filters, power supply controls, motor controls, actuator drivers, and resistive transducers such as strain gauges and pressure, temperature and position sensors. They are also chosen for high side and low side current sensing, Hall effect sensors, test and measurement equipment, industrial process controllers, and signal conditioning circuits.
The -40 to +125 degrees C operating temperature range allows for operation in industrial and automotive environments. Automotive-qualified variants are available.
The op amps are part of ST’s 10-year longevity program. The TSB511, TSB512, and TSB514 are in production now. They are available in Mini SO8, SO8, SOT23-5, TSSOP14, and SO14 package options with standardised pin assignments.
