The OPA2227 operational amplifier combines low noise and wide bandwidth with high precision to make it the ideal choice for applications requiring both ac and precision dc performance.

The OPA2227 is unity-gain stable and features high slew rate (2.3 V/µs) and wide bandwidth (8 MHz).

The OPA2227 operational amplifier is ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applications requiring high precision.

The OPA2227 operational amplifier is a pin-for-pin replacement for the industry standard OP-27 with substantial improvements across the board. The dual and quad versions are available for space savings and perchannel cost reduction.

The OPA2227 is available in an SOIC-8 package. Operation is specified from –55°C to 125°C.
