STMicroelectronics announces the release of its new range of operational amplifiers. The new high-accuracy TSZ151 operational amplifiers from ST are touted to have very low offset voltage with minimal temperature drift.
The new operational amplifiers from ST bring enhanced accuracy and stability to circuits for sensor interfacing, signal conditioning, and current measurement.
An extremely low input offset voltage (Vio) is the defining parameter of a high-accuracy operational amplifier (op amp).
With gain bandwidth of 1.6MHz and drawing just 210?A at 5V, the TSZ151 sits between ST’s 400kHz 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 an ultra-low maximum input bias current of 300pA.
Having a minimum operating voltage of 1.8V, the TSZ151 operational amplifiers 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?A at 5V, while the low supply-voltage capability permits extended runtime with a discharged battery.
Leveraging its wide operating temperature range, from -40°C to +125°C, designers can use the TSZ151 in equipment to be deployed in harsh environments and in applications with long mission profiles.
Applications Include
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.
Availability, Packaging and Pricing
The TSZ151 is in mass production now and available in a choice of tiny SC70-5 and SOT23-5 packages. Free samples are available at ST’s eStore and pricing starts at $0.58 for 1000 units.
