Suitable for measurement applications such as biosignal monitors and industrial sensors
Can reduce board space and requires no adjustment during the production process

STMicroelectronics (hereinafter ST) has launched the dual precision op-amp TSZ182.

The TSZ182 combines very low and stable input offset voltage, 3MHz gain bandwidth, and rail-to-rail input/output, offered in an ultra-compact 2mm x 2mm DFN8 or small SO8 package option.

The new chopper-stabilized TSZ182, launched to complement ST's existing op-amps, is suitable for measurement applications such as biosignal monitors, blood glucose meters, industrial sensors, factory automation, and low-side current sensing.



ST explained that the TSZ182 provides high measurement resolution and accuracy with an offset voltage of 25µV at 25°C without requiring external trimming components, thereby reducing board space and eliminating the need for adjustment during the production process.

Additionally, with an offset drift below 100nV/°C, accuracy is maintained over a wide temperature range, and by periodically storing auto-calibration values, the design is simplified and focus is placed on user convenience.

Compared to competing products, the TSZ182 features an operating voltage of 2.2V to 5.5V and rail-to-rail input/output capability, maximizing the available dynamic range. With a 3MHz gain bandwidth, it guarantees consistent frequency response across a wide range, and with a maximum operating current of only 1mA at 5V, it maximizes runtime for battery-powered devices. It operates across a temperature range of -40°C to 125°C, enabling use in external environments.
