ADA4691-4ACPZ-R2

ADA4691-4 is a rail-to-rail output, single-supply amplifier featuring low power, wide bandwidth, and low noise. This amplifier is ideal for a wide variety of applications. Audio, filters, photodiode amplifiers, and charge amplifiers, all benefit from this combination of performance and features. Additional applications for this amplifier include portable consumer audio players with low noise and low distortion that provide high gain and slew rate response over the audio band at low power. Industrial applications with high impedance sensors, such as pyroelectric and IR sensors, benefit from the high impedance and low 0.5pA input bias, low offset drift, and enough bandwidth and response for low gain applications. It is used in applications such as photodiode amplifiers, sensor amplifiers, portable medical and instrumentation, portable audio: MP3s, PDAs, and smartphones, communications, low-side current sense, ADC drivers, active filters, sample-and-hold.
