Devices have specified temperature range of –40°C to +125°C. This performance isavailable in very small, 8-pin MSOP packaging.400nV PP0.1Hz to 10Hz NoiseApplications• Precision ±10V input front-ends• Transimpedance amplifiers• Active filters• ADC drivers• DAC output buffer• High-performance audio200nV PP /Div+15V+5V3.6mA I Q250µVOPA827ADS8505±10VInput1600nV PPClosest Competition–15V1s/Div Frequency (Hz)OPA827 features extremely low noise for data acquisition.*Expected Release Date 4Q 2007.Low Input Bias Current Operational Amplifiers (I B ≤ 10pA)I Q Per Slew V OS V OS V N atV S V S Ch.
