STMicroelectronics – 5V CMOS op amp offers very high accuracy and fast signal conditioning

STMicroelectronics’ TSZ182 is a dual operational amplifier which features a very low input-offset voltage and almost no temperature drift.

The offset voltage is a maximum 25μV at 25°C, just 35μV over the full operating-temperature range of -40°C to 125°C. Offset voltage drift is a tiny 0.1μV/°C (maximum).

The TSZ182, which has a 3MHz gain-bandwidth product and 4.7V/μs slew rate, offers an excellent ratio of speed to power consumption, and draws just 1mA at 5V.

Input bias current is also very low: 300pA maximum over the full operating-temperature range.

These features make the TSZ182 ideal for sensor interfaces that require high accuracy and high bandwidth.
