The TSZ151 op amps have very low offset voltage with minimal temperature drift, offering high accuracy and stability to circuits for sensor interfacing, signal conditioning, and current measurement.
With gain-bandwidth of 1.6 MHz and drawing just 210 μA at 5 V, the TSZ151 sits between ST’s 400 kHz TSZ121 and 3MHz TSZ181, giving designers more choice and flexibility to optimize speed and power consumption. The TSZ151 combines its excellent speed-to-power ratio with ultra-low maximum input bias current of 300 pA.
Having a minimum operating voltage of 1.8 V, the TSZ151 can be powered from the same rail as other ICs in the system, such as a low-voltage microcontroller. The rail-to-rail input and output help maximize dynamic range. The op amp also has very low power consumption, drawing just 210 μA at 5 V, while the low supply-voltage capability permits extended runtime with a discharged battery.
Leveraging its wide operating temperature range, from -40 to +125°C, designers can use the TSZ151 in equipment to be deployed in harsh environments and in applications with long mission profiles. Typical uses include feedback circuitry in power supplies for industrial, server and telecom-infrastructure applications, and automotive high-accuracy signal conditioning and power conversion. The TSZ151 is AEC-Q100 qualified and is covered by ST’s rolling 10-year longevity plan that guarantees long-term product support.
Currently in mass production, the TSZ151 is offered in compact SC70-5 and SOT23-5 packages.
