New op amps bring high-accuracy sensing to industrial and automotive applications

The TSZ151 operational amplifiers from STMicroelectronics, which offer low offset and zero drift, provide wide gain bandwidth in, sensor interfacing, signal conditioning and power conversion circuits.

The AEC-Q100-qualified TSZ151 from STMicroelectronics is a single operational amplifier which provides very accurate signal conditioning due to very low offset voltage and high temperature stability.

Producing almost zero drift over the operating-temperature range, this op amp is ideal for high-accuracy sensor interfaces.

Offering an excellent speed/power consumption ratio, the TSZ151 features a 1.6 MHz gain-bandwidth product while drawing just 210 µA at 5 V. The op amp also features an ultra-low input bias current.
