STMicroelectronics has added the TSV782 high-performance dual op-amp to its 5-V family, with 30-MHz gain bandwidth (GBW) and 50-µV (typical) input offset voltage for high-speed, high-accuracy signal conditioning.
Able to function with a supply as low as 2.0 V, the TSV782 can operate from a deeply discharged battery and so extend the runtime of equipment such as smoke alarms. In addition, the operating current of just 3.3 mA/channel helps designers maximize the application energy budget to power richer functions and capabilities such as innovative smart features and wireless connectivity. Operating down to 2.0 V also lets the op-amp use the same power rail as low-voltage logic devices to simplify system design and lower the bill of materials.
With rail-to-rail input and output and maximum slew rate of 20 V/µs, the TSV782 joins similar rail-to-rail devices in ST’s high-performance family. These include the TSV772, which has GBW of 20 MHz and maximum slew rate 13V/µs, and the 50 MHz TSV792 that operates at 5.5 mA per channel. Further op-amps in the portfolio include the TSV7722 and related products. These have a low-rail input stage optimized for low-side current measurements in power conversion systems.
The high accuracy of ST’s 5-V op-amp family lets designers create circuits that require no trimming or calibration during production, saving expensive external components such as precision resistors and potentiometers. The newly added TSV782 op-amp has maximum input bias current of 300 pA up to 125°C, enabling accurate signal conditioning with high-impedance sensors or in transimpedance configuration.
The TSV782 dual op-amp is in volume production now. Package options include SO-8, MiniSO-8, and a 2- x 2-mm DFN8, which is the smallest package in the industry for this class of op-amp. Free samples are available now and automotive-grade devices in SO-8 and MiniSO-8 will be in full production by the end of 2022.
