The AD8608ARUZ-REEL from Analog Devices is a precision, low noise, CMOS, rail to rail input/output quad operational amplifier in 14 lead TSSOP package. This amplifier uses a Analog Devices patented DigiTrim trimming technique which achieves superior precision without laser trimming. The combination of low offsets, low noise, very low input bias currents, low input voltage, current noise, wide signal bandwidth and high speed makes this amplifier useful in a wide variety of applications. Filters, integrators, photodiode amplifiers and high impedance sensors all benefit from the combination of performance features. Audio and other AC applications benefit from the wide bandwidth and low distortion. The AD8608 has current noise density of0.01pA/√Hz at f = 1KHz, VS = 5V. Applications for these amplifiers include optical control loops, portable and loop powered instrumentation, audio amplification for portable devices, sensors, barcode scanners and multipole filters.
