描述 Description

DESCRIPTION
The OPA827 series of JFET operational amplifiers combines outstanding dc precision with excellent ac performance. It offers 100μV of offset, very low drift (1μV/°C) over temperature, low bias currents, and very low flicker noise of 400nV PP (0.1Hz to 10Hz). It operates over a very wide supply voltage range of ±4V to ±18V on a low 4.5mA supply current. A dual version is also available for the OPA827 family.FEATURES
• OFFSET: 250μV (max)
• DRIFT: 1μV/°C
• LOW NOISE: 4.5nV/√Hz at 1kHz
• BANDWIDTH: 18MHz
• SLEW RATE: 22V/μs
• BIAS CURRENT: 3pA
• QUIESCENT CURRENT: 4.5mA/Ch
• WIDE SUPPLY RANGE: ±4V to ±18V
• SINGLE PACKAGES: MSOP-8, SO-8
• DUAL PACKAGES: SO-8 PowerPAD
