OPA227UAG4 Datasheet

Operational Amplifiers - Op Amps


The OPA227UAG4 series op amps combine low noise and wide bandwidth with high precision to make them the ideal choice for applications requiring both ac and precision dc performance. The OPA227UAG4 is unity-gain stable and features high slew rate] (2.3V/µs) and wide bandwidth (8MHz). The OPA227UAG4 series op amps are ideal for professional audio equipment. In addition, low quiescent current and low cost make them ideal for portable applications requiring high precision. OPA227UAG4 Features • low noise: 3nv/√hz• wide bandwidth: opa227: 8mhz, 2.3v/µs opa228: 33mhz, 10v/µs• settling time: 5µs(significant improvement over op-27)• high cmrr: 138db• high open-loop gain: 160db• low input bias current: 10na max• low offset voltage: 75µv max• wide supply range: ±2.5v to ±18v• opa227 replaces op-27, lt1007, max427• opa228 replaces op-37, lt1037, max437• single, dual, and quad versions OPA227UAG4 Applications • data acquisition• telecom equipment• geophysical analysis• vibration analysis• spectral analysis• professional audio equipment• active filters• power supply control
