HXY MOSFET OPA2335AIDR-HXY

The OPA2335AIDR series amplifiers employ a patented fast-settling chopper stabilization technique to provide input offset voltage correction, achieving ultralow offset and drift. This approach continuously measures and compensates for input offset, eliminating drift over time and temperature as well as 1/f noise. This design breakthrough delivers a 1.5 MHz gain-bandwidth product and a high slew rate of 1.2 V/μs, while consuming only 125 μA of supply current. These devices are unity-gain stable and offer excellent power supply rejection ratio and common-mode rejection ratio. This series is ideal for applications requiring precision amplification of low-level signals where error sources cannot be tolerated, even when high bandwidth and fast transient response are required. Rail-to-rail input and output swing makes both high-side and low-side sensing straightforward. The series operates from a single supply voltage as low as 1.8 V, making it suitable for two-cell battery applications. These op-amps feature enhanced EMI protection to minimize interference from external sources, along with high ESD protection. All versions are specified over the extended industrial temperature range of -40 to +125°C.
