TP27-SR

Overview

The TP27-SR is a high supply voltage operational amplifier from the TP27 series, manufactured by 3PEAK. It features a maximum offset voltage of ±50 μV at 25°C and operates within a supply voltage range of 4.5 V to 36 V. The device provides a gain-bandwidth product of 6 MHz and a slew rate of 5 V/μs. It supports rail-to-rail output and input common-mode voltage extending to the negative supply rail (−VS). Key electrical characteristics include low noise density of 8 nV/√Hz at 1 kHz, excellent EMI suppression performance of 85 dB at 1 GHz, and over-temperature protection. The component is housed in an SOP-8 package and is rated for operation across a temperature range of −40°C to 125°C.

Feature Summary

• High supply voltage capability with differential input voltage range extending to the supply rails, allowing operation as a comparator.
• Input common-mode voltage range extends to the negative supply rail (−VS) while maintaining rail-to-rail output swing.
• Capable of driving any capacitive load without stability issues.
• Features robust EMI suppression performance and integrated over-temperature protection.
