ST’s precision operational amplifier portfolio includes several series covering different voltage ranges, as well as many possible combinations of power consumption and gain bandwidth, allowing customers to get the best performance for the appropriate accuracy.
ST’s precision op amp solutions include zero drift amplifiers and amplifiers with a low offset drift over temperature. Thus the precision op amps from ST are a perfect fit for use with any sensor, including gas, temperature, pressure, and position sensors. Moreover, the rail-to-rail input and output feature allows easy and accurate high-side and low-side sensing.
TSZ chopper operational amplifiers
The TSZ zero drift CMOS amplifier series covers the highest precision op amps featuring very low offset voltages with virtually zero drift over time and temperature.
The TSZ single, dual and quad devices offer a maximum input offset voltage of 5 µV, with a maximum dVIO/dt of 30nv/°C, and moreover a very stable offset voltage whatever the common-mode voltage. The devices also feature rail-to-rail input and output, an excellent speed/power consumption ratio, and 400 kHz gain bandwidth product, while consuming less than 40 μA at 5 V.
These features make the TSZ series ideal for sensor interfaces, driving analog-to-digital converters (ADCs) in battery-powered applications and portable applications.
