STMicroelectronics TSB952 dual operational amplifier

STMicroelectronics has introduced the TSB952 dual operational amplifier (op amp) with 52 MHz gain-bandwidth and a supply current of 3.3 mA per channel at 36 V, delivering high performance for power-conscious designs.

With its wide supply voltage range of 4.5–36 V, the operational amplifier provides design flexibility and can operate from diverse power sources including industry-standard voltage rails. In addition, the wide supply range helps the system withstand large transient spikes and voltage drops. Also featuring rail-to-rail output swing, the op amps fulfil applications that demand a wide dynamic range, such as signal conditioning for power supplies.

The operational amplifier can operate from -40 to 125°C, enabling designers to use the devices in industrial and automotive environments. ST will release AEC-Q101 qualified parts for automotive use later in 2024. All devices have 4 kV ESD tolerance (human body model) and are EMI hardened.

The TSB952 is available in a 3 x 3 mm DFN8 package with wettable flanks that saves space and allows economical PCB designs. It is also available in the SO8 package with standardised pin assignments to facilitate upgrading existing designs for increased performance.

The industrial-grade versions in DFN8 and SO8 are in production now. The automotive-qualified devices are also available now, with free samples of the TSB952 available from ST eStore. The TSB952 is included in ST’s 10-year longevity program, for long-term product availability.
