AD8605ARTZ-REEL7 vs OPA340MDBVTEP vs AD8615AUJZ-REEL7 Comparison

The AD8605ARTZ-REEL7 is a single input and output, single-supply Operational Amplifier IC, features very low offset voltage, low input voltage and current noise and wide signal bandwidth. They use the Analogue Devices, Inc. patented DigiTrim® trimming technique, which achieves superior precision without laser trimming. The combination of low offsets, low noise, very low input bias currents and high speed makes these amplifiers 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. This device supports extended industrial temperature range.

The OPA340MDBVTEP is a single CMOS Operational Amplifier optimized for low-voltage and single-supply operation. Rail-to-rail input/output and high-speed operation make it ideal for driving sampling analog-to-digital (A/D) converters. The OPA340 is also well-suited for general purpose and audio applications as well as providing current/voltage conversion at the output of digital-to-analog (D/A) converters. The OPA340 operates on a single supply as low as 2.7V with an input common-mode voltage range that extends 500mV below ground and 500mV above the positive supply. Output voltage swing is to within 1mV of the supply rails with a 100kR load. It offers excellent dynamic response (BW=5.5MHz, SR=6V/µs), yet quiescent current is only 750µA.
