TheTexas Instruments OPA2227U is a high-performance operational amplifier. The op amp is packaged in SOIC-8 and has a dual-channel design, which is suitable for a variety of high-precision, low-noise circuit applications. Its wide operating temperature range from -55 ° C to 125 ° C (or -40 ° C to 85 ° C, depending on application conditions) ensures stable operation in different environments.

OPA2227U features

High accuracy and low noise: The OPA2227U is known for its high accuracy and low noise characteristics, and the input voltage noise density is only 3.5nV /√Hz, which is ideal for noise sensitive applications.
Wide bandwidth and high conversion rate: The op amp has a gain bandwidth product of 8MHz and a conversion rate of 2.3V/μs to meet the needs of high-speed signal processing.
High common-mode rejection ratio: its common-mode rejection ratio is up to 120dB (some data mention up to 138dB), which effectively inhibits the interference of common-mode signals and improves the purity of signals.
Wide power supply voltage range: The OPA2227U supports single or dual power supply, and the power supply voltage range is between ±2.5V and ±18V, providing designers with flexible power supply options.
Low input bias current: the input bias current is only 2.5nA (some data mention 10nA, the specific value may vary depending on the test conditions), which helps to reduce the offset error of the input circuit.
